*FAQ: Such a huge project makes it impossible to cover everything in one video, so here's a bit more information about why we did things the way we did!* - The biggest challenge in this project was integrating and tuning our system, because big hydraulics, heavy frames, and tons of sensors have a lot of variability that needs to be checked. We used an open-source hexapod library to control how it walks, which has been used on much smaller hexarobots, and works great. Once the mechanical system is more reliable, it will be able to walk easily. - A lot of people asked why we didn't make a scale model, and the answer is quite simple. When you get to multi-ton mechs, scale models provide almost no benefit, because you can't build a scale model the same way you have to build a giant steel machine. A toy version using motors wouldn't teach us anything. And if we built a 1/4 or 1/2 scale version, the cost would almost be the same as the full-size megahex -- because all the components required cost approximately the same, small or large (valves, sensors, even hydraulic cylinders don't change -too- much in size). - This leads into another common fallacy when it comes to science fiction -- Movies like Transformers, or Pacific Rim... simply aren't possible. Doesn't matter how far technology advances, when you get to literal skyscraper sized robots... there's not any materials on earth strong enough to withstand the forces of such a big mech! Everyone's familiar with the common saying "The Bigger They Are, The Harder They Fall". And that really sums it up. Why is it you can drop a cat from a few stories up and it's fine, but it's certain death for humans? Because force multiplies with mass. - Why flat feet? We had planned on designing different feet attachments for it (you can see the holes in the plates for mounting), but for the base foot, we went with a large flat foot with rubber pads on the bottom, as the initial goal is just walking on flat ground. Having a big flat foot helps ensure the foot remains parallel to the frame, and the leg perpendicular to the ground. A pointy or rounded foot would increase the risk of the robot "twisting it's ankle" which is the weakest link in the excavators. They aren't designed for angular forces. - Why didn't we do more FEA calculations? FEA calculations are great, but sometimes are just theoretical for best-case scenarios. For the excavators, we didn't design or manufacture them, which makes them an unknown variable that makes it really hard to calculate things for! - Are we going to revisit it? *yes* but it might be a while. We want at the very minimum for it to be able to stand up on display, and walk one leg at a time (the slowest, but most stable hexapod gait)
I’m not 100% sold on the idea that larger ‘mechs are “impossible” due to the force multiplication of their immense weight. It’s really a matter of current materials research not being on par with the physical requirements of such a colossal machine. That being said, even IF we had the materials and technology to build such machines, you’re still putting up a MASSIVE target in a combat environment with significant stability challenges. And then firing massive weapons from said platform. It’s just downright infeasible in any theoretical combat environment we’ve ever devised.
I am studying Robotics and I am blown away by how far you were able to get with this thing. I was implementing a closed loop walking algorithm for Hexapod as part of my thesis and I know how hard it is in simulation let alone irl. You have my biggest respect. I hope people will see how much time and love is needed for things around us to work robustly. Thank you for what you are doing.
As an AutoCAD and Graphic Tech student who loves machinery and engineering but started a little late in life, I’m blown away by not only the patience/knowledge required to step up to this kind of project, but the passion/friendships through this monotonous adventure. Biggest amount of respect to you all, and I wish I could donate to your channel. However, I have followed for more content. You guys are BADAZZ!!! ❤️ 💪
12 E dei a escritura da compra a Baruque, filho de Nerias, filho de Maaséias, na presença de Hanameel, filho de meu tio e na presença das testemunhas, que subscreveram a escritura da compra, e na presença de todos os judeus que se assentavam no pátio da guarda. 13 E dei ordem a Baruque, na presença deles, dizendo: 14 Assim diz o Senhor dos Exércitos, o Deus de Israel: Toma estas escrituras, este auto de compra, tanto a selada, como a aberta, e coloca-as num vaso de barro, para que se possam conservar muitos dias. 15 Porque assim diz o Senhor dos Exércitos, o Deus de Israel: Ainda se comprarão casas, e campos, e vinhas nesta terra. 16 E depois que dei a escritura da compra a Baruque, filho de Nerias, orei ao Senhor, dizendo: 17 Ah Senhor DEUS! Eis que tu fizeste os céus e a terra com o teu grande poder, e com o teu braço estendido; nada há que te seja demasiado difícil; 18 Tu que usas de benignidade com milhares, e retribuis a maldade dos pais ao seio dos filhos depois deles; o grande, o poderoso Deus cujo nome é o Senhor dos Exércitos; 19 Grande em conselho, e magnífico em obras; porque os teus olhos estão abertos sobre todos os caminhos dos filhos dos homens, para dar a cada um segundo os seus caminhos e segundo o fruto das suas obras;
I'm so here for projects like this. Seeing the engineering work, the pride when it was working, the enthusiasm and effort. Yes, it was expensive, and I'm hoping beyond hope that, in the balance, it doesn't leave you in the red.
The sheer amount of dedication, resilience, and tenacity this took was remarkable. It's always painful when the idea in your head takes longer than anticipated. But have to say, the result is one of a kind. Your team pretty much did the impossible! I love the result, or at least the result that was temporary!
@@hacksmith yes, it most certainly was. We put a piece of ourselves into every project, and the project leaves of little piece of itself, in our hearts. Even on unsuccessful projects. Basically, I’m sure your team learned so much from this- and you’ll walk away with an even broader knowledge base that will only benefit you going forward. Keep it up all. We should chat plasma thrust some time.
It looks like the feet need more grip maybe some spikes on the bottom of the feet would help and probably rounding the edges of the feet as to minimise the chance of the feet to get caught just some ideas to help so keep up the great work you guys are doing
As an engineering student myself it was really awesome seeing you guys highlight not just the successes, but the learning opportunities too! I loved having Bogdan walk us through the thought process and emotions at each step, as it gives us a very valuable insight into what truly goes into these videos. Personally this is probably my favourite video you guys have done, kudos to everyone involved! I hope you do more of these mini documentary-style videos instead of the flashier reaction-based videos, so long as they're fun for you guys to produce as well :-) Small side note, seeing you guys just dragging it back and forth on the concrete like that made me laugh as much as it made me grimace 😂
9 Que cada um despedisse livre o seu servo, e cada um a sua serva, hebreu ou hebréia; de maneira que ninguém se fizesse servir deles, sendo judeus, seus irmãos. 10 E obedeceram todos os príncipes, e todo o povo que havia entrado na aliança, que cada um despedisse livre o seu servo, e cada um a sua serva, de maneira que não se fizessem mais servir deles; obedeceram, pois, e os soltaram, 11 Mas depois se arrependeram, e fizeram voltar os servos e as servas que haviam libertado, e os sujeitaram por servos e por servas. 12 Veio, pois, a palavra do Senhor a Jeremias, da parte do Senhor, dizendo: 13 Assim diz o Senhor, Deus de Israel: Eu fiz aliança com vossos pais, no dia em que os tirei da terra do Egito, da casa da servidão, dizendo: 14 Ao fim de sete anos libertareis cada um a seu irmão hebreu, que te for vendido, e te houver servido seis anos, e despedi-lo-ás livre de ti; mas vossos pais não me ouviram, nem inclinaram os seus ouvidos. 15 E vos havíeis hoje arrependido, e fizestes o que é reto aos meus olhos, apregoando liberdade cada um ao seu próximo; e fizestes diante de mim uma aliança, na casa que se chama pelo meu nome; 16 Mudastes, porém, e profanastes o meu nome, e fizestes voltar cada um ao seu servo, e cada um à sua serva, os quais já tínheis despedido libertos conforme a vontade deles; e os sujeitastes, para que se vos fizessem servos e servas. 17 Portanto assim diz o Senhor: Vós não me ouvistes a mim, para apregoardes a liberdade, cada um ao seu irmão, e cada um ao seu próximo; pois eis que eu vos apregôo a liberdade, diz o Senhor, para a espada, para a pestilência, e para a fome; e farei que sejais espanto a todos os reinos da terra.
I actually really like the fact that you're ok with showing how a project failed, because not only is it a very interesting story on its own, but it also gives us a great look at what working on stuff like this is really like. The fact that no project is guaranteed success makes the ones that do succeed all the more impressive.
@@mkisner8060 Yes. Obviously making money is part of the reason they uploaded this, but that's true for any of their videos. It doesn't change the fact that the concept of a documentary style video showing how a project failed is interesting and novel.
You guys are really doing what nobody else could conceive of accomplishing. The existence of this channel is a huge inspiration for people wanting to get into engineering!
Except there's a guy called Matt Denton that goes on tour with the rideable hexapod that he made over a decade ago. So this isn't exactly unheard of. It's just a rehash of someone else's work.
The level of endurance you guys have for these big projects, and the sheer amount of programming and engineering is amazing to see! Too bad this didn’t work out, but I can’t wait to see what you all having coming up next!
10 Leu, pois, Baruque naquele livro as palavras de Jeremias, na casa do Senhor, na câmara de Gemarias, filho de Safã, o escriba, no átrio superior, à entrada da porta nova da casa do Senhor, aos ouvidos de todo o povo. 11 E, ouvindo Micaías, filho de Gemarias, filho de Safã, todas as palavras do Senhor, daquele livro, 12 Desceu à casa do rei, à câmara do escriba. E eis que todos os príncipes estavam ali assentados, a saber: Elisama, o escriba, e Delaías, filho de Semaías, e Elnatã, filho de Acbor, e Gemarias, filho de Safã, e Zedequias, filho de Hananias, e todos os outros príncipes. 13 E Micaías anunciou-lhes todas as palavras que ouvira, quando Baruque leu o livro, aos ouvidos do povo. 14 Então todos os príncipes mandaram Jeudi, filho de Netanias, filho de Selemias, filho de Cusi, a Baruque, para lhe dizer: O rolo que leste aos ouvidos do povo, toma-o na tua mão, e vem. E Baruque, filho de Nerias, tomou o rolo na sua mão, e foi ter com eles. 15 E disseram-lhe: Assenta-te agora, e lê-o aos nossos ouvidos. E leu Baruque aos ouvidos deles. 16 E sucedeu que, ouvindo eles todas aquelas palavras, voltaram-se temerosos uns para os outros, e disseram a Baruque: Sem dúvida alguma anunciaremos ao rei todas estas palavras.
Wow. What a job! You all inspire me to no end. I'm a solo experimenter and get so frustrated at failure after failure after working on it so much then another failure. I have to just walk away. I stayed away from doing ANY of my ideas and experiments because of the failures over and over. When you're by yourself it does a REAL number on you. You all inspired me back to going for it. I have no sponsors or much money so I catch when I can, so to speak. I could feel the frustration and the hope from your project. Thanks for all the hard work. You DO inspire others a lot. Cheers.
20 Tu puseste sinais e maravilhas na terra do Egito até ao dia de hoje, tanto em Israel, como entre os outros homens, e te fizeste um nome, o qual tu tens neste dia. 21 E tiraste o teu povo Israel da terra do Egito, com sinais e com maravilhas, e com mão forte, e com braço estendido, e com grande espanto, 22 E lhes deste esta terra, que juraste a seus pais que lhes havias de dar, terra que mana leite e mel. 23 E entraram nela, e a possuíram, mas não obedeceram à tua voz, nem andaram na tua lei; tudo o que lhes mandaste que fizessem, eles não o fizeram; por isso ordenaste lhes sucedesse todo este mal. 24 Eis aqui os valados; já vieram contra a cidade para tomá-la, e a cidade está entregue na mão dos caldeus, que pelejam contra ela, pela espada, pela fome e pela pestilência; e o que disseste se cumpriu, e eis aqui o estás presenciando. 25 Contudo tu me disseste, ó Senhor DEUS: Compra para ti o campo por dinheiro, e faze que o confirmem testemunhas, embora a cidade já esteja entregue na mão dos caldeus. 26 Então veio a palavra do Senhor a Jeremias, dizendo: 27 Eis que eu sou o Senhor, o Deus de toda a carne; acaso haveria alguma coisa demasiado difícil para mim? 28 Portanto assim diz o SENHOR: Eis que eu entrego esta cidade na mão dos caldeus, e na mão de Nabucodonosor, rei de babilônia, e ele a tomará.
I am a retired engineer from one of the major automobile companies. I spent an equal amount of time in product testing and software design over a 30-year period. There is NO better way to learn than through application. No book will ever teach you all that you learned by doing this project. I have a BSEE and that got me into a company and started with the basics, but it wasn't until I was in the field that my real education started. I can not begin to tell you how amazed I am that you got as far as you did. There are SO many variables to consider. You guys are absolutely amazing and exactly what engineering is about. Do NOT be disappointed in the fact that the frame didn't stand up to durability testing (which is what you ultimately did when trying to figure out how to get it to function). All of those who worked on this project represent who we need driving to a better and more interesting life. Keep up the great work!!
Holy CRAP! That was a hell of a Journey you guys went on to build this thing, and while it's unfortunate that you ultimately had to scrap it; thank you for making this video and showing us what it takes to be an engineer. I'm looking forward to your future projects!
My favorite part was how you solved problems when they arose. Very impressed with your problem solving skills. There's no doubt, with enough resources it would have been a viable product. Well done!
As an engineering student (that has a control theory exam in 2 days), I couldn't ask for a better motivation boost than this video. Being familiar with the subject gives perspective on the immense complexity and scale of this project it truly is insane! So much respect for the team!
perhaps in the future hydraulics will be powerful enough to have full on Metal gear solid esc. mechs/Jak II Blast bots/Gundams…but for now it’s not meant to be ; ( Great effort though! you guys made a definite advancement in robotics right there!
@@user-jf4lt4uk7u There are actually some hydraulics that can support things like the hexapod mech very well but they are EXTREMELY expensive and needing to get six of them will cost more than what its worth
29 E os caldeus, que pelejam contra esta cidade, entrarão nela, e pôr-lhe-ão fogo, e queimarão, as casas sobre cujos terraços queimaram incenso a Baal e ofereceram libações a outros deuses, para me provocarem à ira. 30 Porque os filhos de Israel e os filhos de Judá não fizeram senão mal aos meus olhos, desde a sua mocidade; porque os filhos de Israel nada fizeram senão provocar-me à ira com as obras das suas mãos, diz o Senhor. 31 Porque para a minha ira e para o meu furor me tem sido esta cidade, desde o dia em que a edificaram, e até ao dia de hoje, para que a tirasse da minha presença; 32 Por causa de toda a maldade dos filhos de Israel, e dos filhos de Judá, que fizeram, para me provocarem à ira, eles e os seus reis, os seus príncipes, os seus sacerdotes, e os seus profetas, como também os homens de Judá e os moradores de Jerusalém. 33 E viraram-me as costas, e não o rosto; ainda que eu os ensinava, madrugando e ensinando-os, contudo eles não deram ouvidos, para receberem o ensino. 34 Antes puseram as suas abominações na casa que se chama pelo meu nome, para a profanarem. 35 E edificaram os altos de Baal, que estão no Vale do Filho de Hinom, para fazerem passar seus filhos e suas filhas pelo fogo a Moloque; o que nunca lhes ordenei, nem veio ao meu coração, que fizessem tal abominação, para fazerem pecar a Judá. 36 E por isso agora assim diz o SENHOR, o Deus de Israel, acerca desta cidade, da qual vós dizeis: Já está dada na mão do rei de babilônia, pela espada, pela fome, e pela pestilência: 37 Eis que eu os congregarei de todas as terras, para onde os tenho lançado na minha ira, e no meu furor, e na minha grande indignação; e os tornarei a trazer a este lugar, e farei que habitem nele seguramente.
I mean... the collective engineering work that went into this is insane. The project is an amazing fusion of different disciplines, and really is a fantastic case study in appreciating just how incredibly complex so much of the machinery we take for granted in the modern world is. Thank you for the incredible work on this, and you should all be incredibly proud of what you accomplished.
0 feet per hour. Absolute freedom units. Bruh, this channel is one of the biggest reasons as to why I'm still interested in doing projects outside of computer science. Absolutely marvelous job guys.
To be honest, as an engineer I watched this from the beginning to the end since the video format was quite good, and another reason to support you on a project like this one since I know how hard it could be.
Hopefully way down the line this project can be revisited. But this is definitely a lesson in asking and understanding the important questions before beginning building. Shear stress during turns was definitely something that was majorly underestimated! Don’t let this failure take away from what you built and how close you came to success! We’re all proud of how far this team has come and how ambitious they remain!
I'm a machinist, and while I'm not familiar with creating accurate stress analysis reports, some simple math, and individual destructive testing of critical points to confirm the stress analysis they did do, could have at least proofed out the concept.
We learn the most from our failures. The fact that it was able to walk and turn is a feat of engineering that you guys should be proud of. You figured out how to make it move steadily, adjusted things as needed and over-all made a very solid platform. We won't be seeing mechs anytime soon, but taking little steps like this are a great way forward. As much as I would love to see you guys make a working 6-legged mech, don't kill yourselves over it. Do what you can and keep testing. Isn't that the entire point of the Scientific Method?
An 6 legged mech that could work a bit better would be trying to make another OSU adaptive suspension vehicle , that one is a rather old mech that was hydraulic but it could go to up 30° degree inclines , "run" at 12 kmh , carry an operator and 200 kg of payload , that mech was finished in the 80' so i think a modernized versión could work the same or better
1 A palavra que do SENHOR veio a Jeremias, nos dias de Jeoiaquim, filho de Josias, rei de Judá, dizendo: 2 Vai à casa dos recabitas, e fala com eles, e leva-os à casa do Senhor, a uma das câmaras e dá-lhes vinho a beber. 3 Então tomei a Jazanias, filho de Jeremias, filho de Habazinias, e a seus irmãos, e a todos os seus filhos, e a toda a casa dos recabitas; 4 E os levei à casa do Senhor, à câmara dos filhos de Hanã, filho de Jigdalias, homem de Deus, que estava junto à câmara dos príncipes, que ficava sobre a câmara de Maaséias, filho de Salum, guarda do vestíbulo; 5 E pus diante dos filhos da casa dos recabitas taças cheias de vinho, e copos, e disse-lhes: Bebei vinho. 6 Porém eles disseram: Não beberemos vinho, porque Jonadabe, filho de Recabe, nosso pai, nos ordenou, dizendo: Nunca jamais bebereis vinho, nem vós nem vossos filhos; 7 Não edificareis casa, nem semeareis semente, nem plantareis vinha, nem a possuireis; mas habitareis em tendas todos os vossos dias, para que vivais muitos dias sobre a face da terra, em que vós andais peregrinando. 8 Obedecemos, pois, à voz de Jonadabe, filho de Recabe, nosso pai, em tudo quanto nos ordenou; de maneira que não bebemos vinho em todos os nossos dias, nem nós, nem nossas mulheres, nem nossos filhos, nem nossas filhas; 9 Nem edificamos casas para nossa habitação; nem temos vinha, nem campo, nem semente.
10 Mas habitamos em tendas, e assim obedecemos e fazemos conforme tudo quanto nos ordenou Jonadabe, nosso pai. 11 Sucedeu, porém, que, subindo Nabucodonosor, rei de babilônia, a esta terra, dissemos: Vinde, e vamo-nos a Jerusalém, por causa do exército dos caldeus, e por causa do exército dos sírios; e assim ficamos em Jerusalém. 12 Então veio a palavra do Senhor a Jeremias, dizendo: 13 Assim diz o Senhor dos Exércitos, o Deus de Israel: Vai, e dize aos homens de Judá e aos moradores de Jerusalém: Porventura nunca aceitareis instrução, para ouvirdes as minhas palavras? diz o Senhor. 14 As palavras de Jonadabe, filho de Recabe, que ordenou a seus filhos que não bebessem vinho, foram guardadas; pois não beberam até este dia, antes obedeceram o mandamento de seu pai; a mim, porém, que vos tenho falado, madrugando e falando, não me ouvistes. 15 E vos tenho enviado todos os meus servos, os profetas, madrugando, e insistindo, e dizendo: Convertei-vos, agora, cada um do seu mau caminho, e fazei boas as vossas ações, e não sigais a outros deuses para servi-los; e assim ficareis na terra que vos dei a vós e a vossos pais; porém não inclinastes o vosso ouvido, nem me obedecestes a mim. 16 Visto que os filhos de Jonadabe, filho de Recabe, guardaram o mandamento de seu pai que ele lhes ordenou, mas este povo não me obedeceu, 17 Por isso assim diz o Senhor Deus dos Exércitos, o Deus de Israel: Eis que trarei sobre Judá, e sobre todos os moradores de Jerusalém, todo o mal que falei contra eles; pois lhes tenho falado, e não ouviram; e clamei a eles, e não responderam.
That's honestly one of the coolest things I've seen on RUclips. You guys created something truly amazing and even though it's not complete, maybe a few years down the line it will be possible. Great job guys!
I can't believe how much effort and ressources went into this video when I remember Jame's garage. This isn't much but I'll feel like I contributed to help keep making these projects possible for you guys! Amazing work!
This is what Boston Dynamics has been perfecting over the past three decades since 1992, so it's not as easy to make as it is to imagine. Awesome work, lesson learned, and cool mech!
I am genuinely so proud of Bogdan in being able to sit here and walk us through his project knowing he has to give in in the end. It’s an extreme showing of his strength of character.
if you get anywhere close to that i think it would be an achievement for anyone. thats not giving up actually. its just stopping. time money etc. they actually taught they can do it easy hehe.
Let's be honest. When I first saw the little thumbnail and read the title, I was sure it was some kind of CGI showcase. But no, you guys actually built a huge spider mech and walked with it. My words can't describe how blown away I am. Crazy good work!
This looks like something straight out of Scrap Mechanic! The commitment and perseverance you guys have for your projects, and for us the audience is truly unreal
I am really saddened that this project was put to rest even if it had the real potential of becoming something so much bigger... But I suppose I shouldn't request too much. The fact that the Megahex project carried out this far to begin with is a miracle of its own, and the fact that ya'll cared this much about your passion project that you were working on it despite it making you loose money, to the point that it almost pushed you to bankruptcy... That's wholesome, man! An inspiration to all the aspiring engineers or any other artists at that matter, and a textbook definition of ''Step by step goes a long way.''
I wonder if it would be possible to make it completely analog. Like rather than computer programing to make the legs move just right, it maybe could theoretically be possible to have that all controlled by a gearbox, and the 'pilot' could control the direction with a stick connected to the gears?
As an automation engineer, this is nuts. If I had to program/do wiring and testing this beast, not to mention debugging. The effort to make it moving is insane.
Your team did an incredible job with this. It's amazing to see a RUclips team go at these major projects that seem so advanced, that you'd only expect major government-funded corporations throwing millions of dollars to develop. Very well done
@@Unkn0.n Yes, government crazier things is to how spend all these tons of money for nothing and keep draining them like everything is ok. Only such enthusiasts like Hacksmith industries and others around the world can spend money in proper way. Just because they spend their own money on their own ideas.
I believe that in order for the machine to move naturally and smoothly...we must return to nature and place sensors on the spider’s feet while walking in order to measure the movement of its limbs compared to its abdomen and measure the rise and fall between the legs to discover the correct matrix for the correct walk.
Some ideas: soft foam "shoes" for the metal feet to get acceptance from gardeners. All connector fields are to be oriented downwards and are not soldered but clamped. Restructure the feet so you have raised lever-points to be pistons for the movement of the legs, or at least give them more height, its trying to carry itself around crouched which eats up much of its lifting capability. Remove any cockpit/seating and do it remote controlled with drone cams. Whatever the laptop does automatically should go to an arduino or similar microcomputer. ( more sustainable regarding power consumption )... anyways, super-nice work folks.

The thing I learned here is,,,,,, that There are so many things to take care of even after the machine is build. .. Literally opened my eyes it's crazy and amazing Btw appreciate ur efforts guys
This was a fantastic project. If you guys were to continue tinkering on her, I would recommend automotive frames. Scrapped cars would be perfect even. Large single engine for the whole thing, half inch plates on weak points for reinforcement. But you guys did say that's the end of her, and while sad, I understand completely. Wishing you all the best!
I've done industrial automation and robotics competitions for years. It was really nice to see you all struggle with the same things I struggle with. I can't believe you all got a pid system to control those legs. PWM servos controlling budget hydraulic valves, powering pistons with backlash, on wiggly joints just sounds plain impossible. It's amazing that you all made it look like only a minor hurdle in this whole project.
This will be my very first donation to anyone ever on any platform, but feel like this is the right time to show my thanks in your time of need as a thank you for inspiring me to pursue a career in engineering. Thanks Hacksmith!!!
@@andrewfullington9777 hey ! everyone donates what they can! we cant all have the same job in this life so some will earn more than others, respect those who dont earn as much as you are suggesting that you earn.
I think as an engineer that this project became incredibly difficult because they used existing technology, the arms of excavators and gasoline engines, to create a spider robot. There are many variables that need to be considered for a system like this to work, but they really did an amazing job. I congratulate them, and I loved it
The pain and joy of working on a project and seeing the successes and failures is something I can really relate to. You guys should be insanely proud of the effort around this project. Seeing that first rise gave me goosebumps! Awesome work lads! Keen to see more content (success or failure) :)
Awesome video. I would love to see a detailed breakdown of the software side of this project. This was obviously a huge undertaking to export the model from Solidworks (URDF?), to then manage the joint locations so you could get the nice real-time graphics in RViz and feedback to help config your PID controllers. Awesome job all around, really showed how difficult integration of robotics systems can be.
This just gives me that much more respect for the Factorio devs when they created the Spidertron. Granted you don't have to deal with physical and structural limitations in a video game, but just the control logic by itself is impressive.
@@DFPercush Not trying to undermine the Factorio devs as they have done some amazing work, but admittedly writing the code for a video-game hex-walker type thing is really not very difficult. I say this as a professional software developer who has spent a lot of hobbyist time working in game dev/studying the kinda math that's used to do this stuff. Let me explain further, though so I don't come across as a 'WELL ACKSHUALLY' type asshole lol (sorry if I still do!!): What makes making something like this so insanely difficult (specifically the thing in the video) is as you mentioned the fact that your computer model needs to PERFECTLY match the real world object. That means EVERYTHING needs to be made within incredibly precises parameters. Then on top of that, your sensors need to be incredibly accurate. They can't have any slippage, they can't drift, they can't be noisy. And then even further you need to account for all kinds of mechanical processes in the software that only begin to emerge after testing. For example, the legs flexing under load/stress but not while idled. The feet bending after heavy hits, the sensors slipping due to a sudden unexpected load, etc. In the world of a video game, ALL of that is gone. Making a little spider mech in a video game is genuinely high school level geometry and algebra (for the most part). As a final clarification, I'm not downplaying the Factorio devs. The work they've done to optimize that game to make it run so well, is truly incredible. The amount of shit that's happening in the game every frame is obscene, and to have that all work so smoothly and cleanly is fantastic. I think that's where the admiration should be given, they have quite a few dev blogs written about how they got conveyor belts working (efficiently) for example lol. Also, in case you want 'proof' read about Inverse Kinematics. It's exactly how you accomplish this type of thing. It's the field of math devoted to "I have a robotic arm and it needs to put it's 'hand' here. What angles do all of the joints need to be?". It's an incredibly powerful and fascinating area of math! Anyway, I hope I'm not coming across as an ass here. This is an area of math/engineering I am personally very passionate about so I just love to talk about it!
i cant believe how far this channel has come. i've been a sub for nearly 6 years now and i remember when strapping jets to james's arms was a crazy thing to see. now we're at something as intricate as this? holy crap dude, i cannot even fathom the time, thought, and money that went into this. this channel is one of a kind
18 E entregarei os homens que transgrediram a minha aliança, que não cumpriram as palavras da aliança que fizeram diante de mim, com o bezerro, que dividiram em duas partes, e passaram pelo meio das suas porções; 19 A saber, os príncipes de Judá, e os príncipes de Jerusalém, os eunucos, e os sacerdotes, e todo o povo da terra que passou por meio das porções do bezerro; 20 Entregá-los-ei, digo, na mão de seus inimigos, e na mão dos que procuram a sua morte, e os cadáveres deles servirão de alimento para as aves dos céus e para os animais da terra. 21 E até o rei Zedequias, rei de Judá, e seus príncipes entregarei na mão de seus inimigos e na mão dos que procuram a sua morte, a saber, na mão do exército do rei de babilônia, que já se retirou de vós. 22 Eis que eu darei ordem, diz o Senhor, e os farei voltar a esta cidade, e pelejarão contra ela, e a tomarão, e a queimarão a fogo; e as cidades de Judá porei em assolação, de sorte que ninguém habite nelas.
I showed my 9 yesr old son this to inspire him and show him just what is possible. And as a millwright/electrician showing him that all this is learnable. Amazing stuff guys just amazing
Kyle, this means you need to upgrade the ones in your facility. Big ones like this are way cooler. Might help with whatever ... something ... they are doing at the moment.
Thank you for showing this! As an engineering student who had to abort, what would hopefully have been a world record-setting launch attempt this year, even though we thought tooth and nail to make it. I could relate to every moment of this video
Y'all this thing is a childhood dream come to life! I cannot imagine how much time the team combined sunk into this project, but I think it's totally worth it. At the very least, you can show it off as a non-moving statue in (or near) the showroom. Do we think it's time to revisit the spy car series?
that would be cool, yes. maybe try and give the spy car retractable shields, just came up with that one on the spot but I'm sure you could do something much cooler with it
Very inspiring to see how you achieve a remarkable prototype in a self-organized way. Brilliant! Major companies are well advised to have you on board for brainstorming and problem-solving sessions.
Love your guys' videos. Been watching for years, and I've seen all the ups and downs and changes to the channel. Really impressed with everything you all have been able to do.
I appreciate the strength it took you guys to admit the failure of a project. I didn't feel it was a failure at all. You have crafted a feat of engineering. You proved the concept you were trying to prove. The only failure you are really guilty off is not having an endless supply of resources. And that is really not even worth considering in a reflection on the project IMO. Keep doing what you're doing. May your creativity keep ever flowing!
Holy cow. What an awesome jobs guys! That was amazing. I’m becoming a Patron right now to support these bigger projects. Annnnd I have to admit it makes me feel so lucky that I only have to record my screen in my videos and there’s minimal costs to start projects. That budget had to have been wild. Even better reason to support. EDIT: Just noticed they consolidated mainly to YT memberships over Patreon. So I’m becoming a member!
This is the best project I have even seen before, you guys are crazy and telented, I love you so much. I'd love see more, Just Don't give up for new mech-buildings and I am looking forword to.
I loved this format for videos! Being able to see all the ups and downs of the project made it super enjoyable to watch. You guys are an example of great role models and serve as inspiration to many. Love it!!!
@@hacksmith If you guys EVER have the funding, PLEASE continue this and finish the project!! I love the mech builds and i think so many others do as well. Keep doing what you do, much love
Going through the design process and not achieving the main objective makes you appreciate all the engineers and builders who came before you. My mind re-explodes when I see the SR-71 and think of all the setbacks and obstacles Kelly Johnson and skunk works over came to make that thing fly. Hold your head up high, I’m sure you learned so much during this project.
Seriously, continue, it's something very nice and you are so close to achieving it, you already have all the necessary knowledge, disassemble the legs and motors and place it on a new sturdy frame if you can.
You should take what you've learned from this project to make a smaller project from the ground up. Rather than use existing parts that were manufactured for a specific purpose, get individual pieces that can withstand the stresses involved. That way, you can perfect the design with far lower costs and scale up for a second or third iteration.
I wouldnt do that, as a robotics engineer you want to use prefab modules. There are many things that went wrong here but indeed making a "scaled" version first would have helped identify the control issues. If you try to design/manufacture everything you spend much more time and money. You are better off breaking a few parts instead. In the end it looks as though the machine was creating incredible impulses when dropping the legs, proper non-linear controllers designed for each leg and different feet design would have probably been enough to make it work. Ie, spring dampers to lower the impact, force control with grabity compensation instead of velocity control and a ball joint at the feet would have probably saved it. But none the less this is an incredibly difficult project and the fact they got so far is a massive win. Great work everyone who was involved, absolutely insane stuff!
Okay it might have not gone to plan. But dude that was so cool. And it actually walked. I’ve been wanting to build or see something like this for years. That’s so cool. And the possibility of it being possible if we find strongest material is just so exciting to think about.
and this is just a small company compared to other mechanics giants out there imagine if the Hacksmith had a big budget like 25 million $ that would be even crazier
Yeah. I imagine this project will likely help someone build a similar mech in the future. Maybe not now, maybe not 5 years, but having the knowledge of the problems that could arise helps massively. Imagine there would be further problems further into development but at least these ones are known now.
I am in awe of the wild and wacky projects you've managed to pull off! I don't know how you do it, but keep it up, because you're making the world a more interesting place one project at a time.
Enjoyed the documentary style filming on this one - the sit down and explain things, talking to the camera and narrating, is a great way to tell a story. Keep em coming. .
This project was 100% a success in my eyes tbh. You smashed it Bogdan and everyone involved! For such a small team and such high ambitions you done a bang up job. You should be proud you got it to where it is! But hey maybe in time you can re-visit and perfect the craft. Keep up the amazing work lads. We’re watching and supporting!
I don’t normally comment on videos often, but I thought that the amount of work and dedication that went into this deserves to be know and apparently comments help the algorithm. It was extremely interesting and amazing that you could pull off this no matter how well it did!
"My grandpa made that suggestion...like 6 months ago". There is something so cool about that comment. Love the enthusiasm with these young guys, and the old timer still has excellent ideas. Very cool!
Love your videos and I love seeing you guys make things that can seem impossible, but be able to make them possible. One failed project can still lead to a successful project later down the line.
"Failures are the pillars to succes ." The hardworking, dedication, efforts , minds all are the products coupled with luck and engineering has finally paid of . Not saying this whole so sick project was a walk in the park , but the final product was worth it . Hacksmith industry guy , you guys are awesome. Enjoy it man . Spider mech is crawling baby !
The amount of perseverance it took to continue working on this despite all of the failures is amazing. I really admire you all for continuing to work on it and getting it to the point where it could walk how it did. I love this channel and all of the amazing engineering feats you achieve.
mad respect not just releasing the first 3 parts of this video to try to gain revenue, but to make a great video show-placing the ups and downs of what something like this takes. Big resepect.
I really dig that you aren’t skipping over the failures, but showing how you persevere and learn from them. So often we’re only shown perfect end results and it sets up unrealistic expectations. Showing the hard work and determination is so important
Absolutely thank you for posting this video and don't ever think of it as a failure. Failure isn't making mistakes, it's continuing to make the same mistakes. This project you learned and grew in experience. That is an invaluable lesson to teach our youth. Don't ever give up!
This kind of project is just amazing to me. The persistence and effort you guys put into these videos are really what set you above. Keep it up guys much love
Thank you so much for everything you do, your channel got me into engineering, and thanks to y’all, I had the drive to get my ass into a good engineering college. thank you so much.
In a world where kids want to grow up and be internet famous now, these kinds of videos will keep those real thinkers’ heads above the water. Thanks for being so innovative in todays world! I’m scared we will lose passionate thinkers like you guys in the next generations.
This was incredible! I'm so glad this did get green lit because inspiring engineers need to see this kind of effort and what you get out of it, even if it doesn't work out as expected. I'm also sure there was a lot of take aways that will transfer to future projects. Please keep up the great work!
*FAQ: Such a huge project makes it impossible to cover everything in one video, so here's a bit more information about why we did things the way we did!*
- The biggest challenge in this project was integrating and tuning our system, because big hydraulics, heavy frames, and tons of sensors have a lot of variability that needs to be checked. We used an open-source hexapod library to control how it walks, which has been used on much smaller hexarobots, and works great. Once the mechanical system is more reliable, it will be able to walk easily.
- A lot of people asked why we didn't make a scale model, and the answer is quite simple. When you get to multi-ton mechs, scale models provide almost no benefit, because you can't build a scale model the same way you have to build a giant steel machine. A toy version using motors wouldn't teach us anything. And if we built a 1/4 or 1/2 scale version, the cost would almost be the same as the full-size megahex -- because all the components required cost approximately the same, small or large (valves, sensors, even hydraulic cylinders don't change -too- much in size).
- This leads into another common fallacy when it comes to science fiction -- Movies like Transformers, or Pacific Rim... simply aren't possible. Doesn't matter how far technology advances, when you get to literal skyscraper sized robots... there's not any materials on earth strong enough to withstand the forces of such a big mech! Everyone's familiar with the common saying "The Bigger They Are, The Harder They Fall". And that really sums it up. Why is it you can drop a cat from a few stories up and it's fine, but it's certain death for humans? Because force multiplies with mass.
- Why flat feet? We had planned on designing different feet attachments for it (you can see the holes in the plates for mounting), but for the base foot, we went with a large flat foot with rubber pads on the bottom, as the initial goal is just walking on flat ground. Having a big flat foot helps ensure the foot remains parallel to the frame, and the leg perpendicular to the ground. A pointy or rounded foot would increase the risk of the robot "twisting it's ankle" which is the weakest link in the excavators. They aren't designed for angular forces.
- Why didn't we do more FEA calculations? FEA calculations are great, but sometimes are just theoretical for best-case scenarios. For the excavators, we didn't design or manufacture them, which makes them an unknown variable that makes it really hard to calculate things for!
- Are we going to revisit it? *yes* but it might be a while. We want at the very minimum for it to be able to stand up on display, and walk one leg at a time (the slowest, but most stable hexapod gait)
That's really cool. I'm glad you guys stuck with it, I'm sure it was really hard. And thanks for the FAQ!
Ty for faq
I’m not 100% sold on the idea that larger ‘mechs are “impossible” due to the force multiplication of their immense weight. It’s really a matter of current materials research not being on par with the physical requirements of such a colossal machine.
That being said, even IF we had the materials and technology to build such machines, you’re still putting up a MASSIVE target in a combat environment with significant stability challenges. And then firing massive weapons from said platform. It’s just downright infeasible in any theoretical combat environment we’ve ever devised.
How are you guys doing? Dont forgot to take care of you both your mentle and physicale health guy good luck and thank for your hard work
ty for the FAQ and this project was ABSOLUTELY *INSANE*
I am studying Robotics and I am blown away by how far you were able to get with this thing. I was implementing a closed loop walking algorithm for Hexapod as part of my thesis and I know how hard it is in simulation let alone irl. You have my biggest respect.

12 E dei a escritura da compra a Baruque, filho de Nerias, filho de Maaséias, na presença de Hanameel, filho de meu tio e na presença das testemunhas, que subscreveram a escritura da compra, e na presença de todos os judeus que se assentavam no pátio da guarda.
13 E dei ordem a Baruque, na presença deles, dizendo:
14 Assim diz o Senhor dos Exércitos, o Deus de Israel: Toma estas escrituras, este auto de compra, tanto a selada, como a aberta, e coloca-as num vaso de barro, para que se possam conservar muitos dias.
15 Porque assim diz o Senhor dos Exércitos, o Deus de Israel: Ainda se comprarão casas, e campos, e vinhas nesta terra.

As an engineering student myself it was really awesome seeing you guys highlight not just the successes, but the learning opportunities too! I loved having Bogdan walk us through the thought process and emotions at each step, as it gives us a very valuable insight into what truly goes into these videos.

9 Que cada um despedisse livre o seu servo, e cada um a sua serva, hebreu ou hebréia; de maneira que ninguém se fizesse servir deles, sendo judeus, seus irmãos.
10 E obedeceram todos os príncipes, e todo o povo que havia entrado na aliança, que cada um despedisse livre o seu servo, e cada um a sua serva, de maneira que não se fizessem mais servir deles; obedeceram, pois, e os soltaram,
11 Mas depois se arrependeram, e fizeram voltar os servos e as servas que haviam libertado, e os sujeitaram por servos e por servas.
12 Veio, pois, a palavra do Senhor a Jeremias, da parte do Senhor, dizendo:
13 Assim diz o Senhor, Deus de Israel: Eu fiz aliança com vossos pais, no dia em que os tirei da terra do Egito, da casa da servidão, dizendo:
14 Ao fim de sete anos libertareis cada um a seu irmão hebreu, que te for vendido, e te houver servido seis anos, e despedi-lo-ás livre de ti; mas vossos pais não me ouviram, nem inclinaram os seus ouvidos.
15 E vos havíeis hoje arrependido, e fizestes o que é reto aos meus olhos, apregoando liberdade cada um ao seu próximo; e fizestes diante de mim uma aliança, na casa que se chama pelo meu nome;
16 Mudastes, porém, e profanastes o meu nome, e fizestes voltar cada um ao seu servo, e cada um à sua serva, os quais já tínheis despedido libertos conforme a vontade deles; e os sujeitastes, para que se vos fizessem servos e servas.
17 Portanto assim diz o Senhor: Vós não me ouvistes a mim, para apregoardes a liberdade, cada um ao seu irmão, e cada um ao seu próximo; pois eis que eu vos apregôo a liberdade, diz o Senhor, para a espada, para a pestilência, e para a fome; e farei que sejais espanto a todos os reinos da terra.

I am a retired engineer from one of the major automobile companies. I spent an equal amount of time in product testing and software design over a 30-year period. There is NO better way to learn than through application. No book will ever teach you all that you learned by doing this project. I have a BSEE and that got me into a company and started with the basics, but it wasn't until I was in the field that my real education started. I can not begin to tell you how amazed I am that you got as far as you did. There are SO many variables to consider. You guys are absolutely amazing and exactly what engineering is about. Do NOT be disappointed in the fact that the frame didn't stand up to durability testing (which is what you ultimately did when trying to figure out how to get it to function). All of those who worked on this project represent who we need driving to a better and more interesting life. Keep up the great work!!
Holy CRAP! That was a hell of a Journey you guys went on to build this thing, and while it's unfortunate that you ultimately had to scrap it; thank you for making this video and showing us what it takes to be an engineer. I'm looking forward to your future projects!
My favorite part was how you solved problems when they arose. Very impressed with your problem solving skills. There's no doubt, with enough resources it would have been a viable product. Well done!

29 E os caldeus, que pelejam contra esta cidade, entrarão nela, e pôr-lhe-ão fogo, e queimarão, as casas sobre cujos terraços queimaram incenso a Baal e ofereceram libações a outros deuses, para me provocarem à ira.
30 Porque os filhos de Israel e os filhos de Judá não fizeram senão mal aos meus olhos, desde a sua mocidade; porque os filhos de Israel nada fizeram senão provocar-me à ira com as obras das suas mãos, diz o Senhor.
31 Porque para a minha ira e para o meu furor me tem sido esta cidade, desde o dia em que a edificaram, e até ao dia de hoje, para que a tirasse da minha presença;
32 Por causa de toda a maldade dos filhos de Israel, e dos filhos de Judá, que fizeram, para me provocarem à ira, eles e os seus reis, os seus príncipes, os seus sacerdotes, e os seus profetas, como também os homens de Judá e os moradores de Jerusalém.
33 E viraram-me as costas, e não o rosto; ainda que eu os ensinava, madrugando e ensinando-os, contudo eles não deram ouvidos, para receberem o ensino.
34 Antes puseram as suas abominações na casa que se chama pelo meu nome, para a profanarem.
35 E edificaram os altos de Baal, que estão no Vale do Filho de Hinom, para fazerem passar seus filhos e suas filhas pelo fogo a Moloque; o que nunca lhes ordenei, nem veio ao meu coração, que fizessem tal abominação, para fazerem pecar a Judá.
36 E por isso agora assim diz o SENHOR, o Deus de Israel, acerca desta cidade, da qual vós dizeis: Já está dada na mão do rei de babilônia, pela espada, pela fome, e pela pestilência:
37 Eis que eu os congregarei de todas as terras, para onde os tenho lançado na minha ira, e no meu furor, e na minha grande indignação; e os tornarei a trazer a este lugar, e farei que habitem nele seguramente.

0 feet per hour. Absolute freedom units. Bruh, this channel is one of the biggest reasons as to why I'm still interested in doing projects outside of computer science. Absolutely marvelous job guys.
To be honest, as an engineer I watched this from the beginning to the end since the video format was quite good, and another reason to support you on a project like this one since I know how hard it could be.

Hopefully way down the line this project can be revisited. But this is definitely a lesson in asking and understanding the important questions before beginning building. Shear stress during turns was definitely something that was majorly underestimated!
Don’t let this failure take away from what you built and how close you came to success! We’re all proud of how far this team has come and how ambitious they remain!
I'm a machinist, and while I'm not familiar with creating accurate stress analysis reports, some simple math, and individual destructive testing of critical points to confirm the stress analysis they did do, could have at least proofed out the concept.
well... if anything they did have a MVP, even if it's a "single test" only MVP that ends in a week of repair...
We learn the most from our failures. The fact that it was able to walk and turn is a feat of engineering that you guys should be proud of. You figured out how to make it move steadily, adjusted things as needed and over-all made a very solid platform. We won't be seeing mechs anytime soon, but taking little steps like this are a great way forward.
As much as I would love to see you guys make a working 6-legged mech, don't kill yourselves over it. Do what you can and keep testing. Isn't that the entire point of the Scientific Method?
An 6 legged mech that could work a bit better would be trying to make another OSU adaptive suspension vehicle , that one is a rather old mech that was hydraulic but it could go to up 30° degree inclines , "run" at 12 kmh , carry an operator and 200 kg of payload , that mech was finished in the 80' so i think a modernized versión could work the same or better
1 A palavra que do SENHOR veio a Jeremias, nos dias de Jeoiaquim, filho de Josias, rei de Judá, dizendo:
2 Vai à casa dos recabitas, e fala com eles, e leva-os à casa do Senhor, a uma das câmaras e dá-lhes vinho a beber.
3 Então tomei a Jazanias, filho de Jeremias, filho de Habazinias, e a seus irmãos, e a todos os seus filhos, e a toda a casa dos recabitas;
4 E os levei à casa do Senhor, à câmara dos filhos de Hanã, filho de Jigdalias, homem de Deus, que estava junto à câmara dos príncipes, que ficava sobre a câmara de Maaséias, filho de Salum, guarda do vestíbulo;
5 E pus diante dos filhos da casa dos recabitas taças cheias de vinho, e copos, e disse-lhes: Bebei vinho.
6 Porém eles disseram: Não beberemos vinho, porque Jonadabe, filho de Recabe, nosso pai, nos ordenou, dizendo: Nunca jamais bebereis vinho, nem vós nem vossos filhos;
7 Não edificareis casa, nem semeareis semente, nem plantareis vinha, nem a possuireis; mas habitareis em tendas todos os vossos dias, para que vivais muitos dias sobre a face da terra, em que vós andais peregrinando.
8 Obedecemos, pois, à voz de Jonadabe, filho de Recabe, nosso pai, em tudo quanto nos ordenou; de maneira que não bebemos vinho em todos os nossos dias, nem nós, nem nossas mulheres, nem nossos filhos, nem nossas filhas;
9 Nem edificamos casas para nossa habitação; nem temos vinha, nem campo, nem semente.
Raiden: Armstrong, impressive little toy you got there!
10 Mas habitamos em tendas, e assim obedecemos e fazemos conforme tudo quanto nos ordenou Jonadabe, nosso pai.
11 Sucedeu, porém, que, subindo Nabucodonosor, rei de babilônia, a esta terra, dissemos: Vinde, e vamo-nos a Jerusalém, por causa do exército dos caldeus, e por causa do exército dos sírios; e assim ficamos em Jerusalém.
12 Então veio a palavra do Senhor a Jeremias, dizendo:
13 Assim diz o Senhor dos Exércitos, o Deus de Israel: Vai, e dize aos homens de Judá e aos moradores de Jerusalém: Porventura nunca aceitareis instrução, para ouvirdes as minhas palavras? diz o Senhor.
14 As palavras de Jonadabe, filho de Recabe, que ordenou a seus filhos que não bebessem vinho, foram guardadas; pois não beberam até este dia, antes obedeceram o mandamento de seu pai; a mim, porém, que vos tenho falado, madrugando e falando, não me ouvistes.
15 E vos tenho enviado todos os meus servos, os profetas, madrugando, e insistindo, e dizendo: Convertei-vos, agora, cada um do seu mau caminho, e fazei boas as vossas ações, e não sigais a outros deuses para servi-los; e assim ficareis na terra que vos dei a vós e a vossos pais; porém não inclinastes o vosso ouvido, nem me obedecestes a mim.
16 Visto que os filhos de Jonadabe, filho de Recabe, guardaram o mandamento de seu pai que ele lhes ordenou, mas este povo não me obedeceu,
17 Por isso assim diz o Senhor Deus dos Exércitos, o Deus de Israel: Eis que trarei sobre Judá, e sobre todos os moradores de Jerusalém, todo o mal que falei contra eles; pois lhes tenho falado, e não ouviram; e clamei a eles, e não responderam.

That's honestly one of the coolest things I've seen on RUclips. You guys created something truly amazing and even though it's not complete, maybe a few years down the line it will be possible. Great job guys!

I am genuinely so proud of Bogdan in being able to sit here and walk us through his project knowing he has to give in in the end. It’s an extreme showing of his strength of character.
if you get anywhere close to that i think it would be an achievement for anyone. thats not giving up actually. its just stopping. time money etc. they actually taught they can do it easy hehe.
Let's be honest. When I first saw the little thumbnail and read the title, I was sure it was some kind of CGI showcase. But no, you guys actually built a huge spider mech and walked with it. My words can't describe how blown away I am. Crazy good work!

I'm not sure if someone already mention it but this project reminds of the Tarantula vehicle from the Hill Climb Racing game
*Collective consciousness starts playing* METALGEAR EXELSUS!
I am really saddened that this project was put to rest even if it had the real potential of becoming something so much bigger... But I suppose I shouldn't request too much. The fact that the Megahex project carried out this far to begin with is a miracle of its own, and the fact that ya'll cared this much about your passion project that you were working on it despite it making you loose money, to the point that it almost pushed you to bankruptcy... That's wholesome, man! An inspiration to all the aspiring engineers or any other artists at that matter, and a textbook definition of ''Step by step goes a long way.''
I wonder if it would be possible to make it completely analog. Like rather than computer programing to make the legs move just right, it maybe could theoretically be possible to have that all controlled by a gearbox, and the 'pilot' could control the direction with a stick connected to the gears?
@@-jank-willson that would be so much stress that it'll probably snap instantly

@@Unkn0.n Yes, government crazier things is to how spend all these tons of money for nothing and keep draining them like everything is ok. Only such enthusiasts like Hacksmith industries and others around the world can spend money in proper way. Just because they spend their own money on their own ideas.
I believe that in order for the machine to move naturally and smoothly...we must return to nature and place sensors on the spider’s feet while walking in order to measure the movement of its limbs compared to its abdomen and measure the rise and fall between the legs to discover the correct matrix for the correct walk.

Some ideas: soft foam "shoes" for the metal feet to get acceptance from gardeners. All connector fields are to be oriented downwards and are not soldered but clamped.
Restructure the feet so you have raised lever-points to be pistons for the movement of the legs, or at least give them more height, its trying to carry itself around crouched which eats up much of its lifting capability. Remove any cockpit/seating and do it remote controlled with drone cams. Whatever the laptop does automatically should go to an arduino or similar microcomputer. ( more sustainable regarding power consumption )... anyways, super-nice work folks.

FAQ: Such a huge project makes it impossible to cover everything in one video, so here's a bit more information about why we did things the way we did!
- The biggest challenge in this project was integrating and tuning our system, because big hydraulics, heavy frames, and tons of sensors have a lot of variability that needs to be checked. We used an open-source hexapod library to control how it walks, which has been used on much smaller hexarobots, and works great. Once the mechanical system is more reliable, it will be able to walk easily.
- A lot of people asked why we didn't make a scale model, and the answer is quite simple. When you get to multi-ton mechs, scale models provide almost no benefit, because you can't build a scale model the same way you have to build a giant steel machine. A toy version using motors wouldn't teach us anything. And if we built a 1/4 or 1/2 scale version, the cost would almost be the same as the full-size megahex -- because all the components required cost approximately the same, small or large (valves, sensors, even hydraulic cylinders don't change -too- much in size).
- This leads into another common fallacy when it comes to science fiction -- Movies like Transformers, or Pacific Rim... simply aren't possible. Doesn't matter how far technology advances, when you get to literal skyscraper sized robots... there's not any materials on earth strong enough to withstand the forces of such a big mech! Everyone's familiar with the common saying "The Bigger They Are, The Harder They Fall". And that really sums it up. Why is it you can drop a cat from a few stories up and it's fine, but it's certain death for humans? Because force multiplies with mass.
- Why flat feet? We had planned on designing different feet attachments for it (you can see the holes in the plates for mounting), but for the base foot, we went with a large flat foot with rubber pads on the bottom, as the initial goal is just walking on flat ground. Having a big flat foot helps ensure the foot remains parallel to the frame, and the leg perpendicular to the ground. A pointy or rounded foot would increase the risk of the robot "twisting it's ankle" which is the weakest link in the excavators. They aren't designed for angular forces.
- Why didn't we do more FEA calculations? FEA calculations are great, but sometimes are just theoretical for best-case scenarios. For the excavators, we didn't design or manufacture them, which makes them an unknown variable that makes it really hard to calculate things for!
- Are we going to revisit it? *yes* but it might be a while. We want at the very minimum for it to be able to stand up on display, and walk one leg at a time (the slowest, but most stable hexapod gait)
Man I love every part of your videos every time they are posted
The thing I learned here is,,,,,, that There are so many things to take care of even after the machine is build. .. Literally opened my eyes it's crazy and amazing

Large single engine for the whole thing, half inch plates on weak points for reinforcement. But you guys did say that's the end of her, and while sad, I understand completely. Wishing you all the best!
I've done industrial automation and robotics competitions for years. It was really nice to see you all struggle with the same things I struggle with. I can't believe you all got a pid system to control those legs. PWM servos controlling budget hydraulic valves, powering pistons with backlash, on wiggly joints just sounds plain impossible. It's amazing that you all made it look like only a minor hurdle in this whole project.

I think as an engineer that this project became incredibly difficult because they used existing technology, the arms of excavators and gasoline engines, to create a spider robot.

@@ctforants6246 same
Awesome video. I would love to see a detailed breakdown of the software side of this project. This was obviously a huge undertaking to export the model from Solidworks (URDF?), to then manage the joint locations so you could get the nice real-time graphics in RViz and feedback to help config your PID controllers. Awesome job all around, really showed how difficult integration of robotics systems can be.
This just gives me that much more respect for the Factorio devs when they created the Spidertron. Granted you don't have to deal with physical and structural limitations in a video game, but just the control logic by itself is impressive.
@@DFPercush same here
@@DFPercush Not trying to undermine the Factorio devs as they have done some amazing work, but admittedly writing the code for a video-game hex-walker type thing is really not very difficult. I say this as a professional software developer who has spent a lot of hobbyist time working in game dev/studying the kinda math that's used to do this stuff. Let me explain further, though so I don't come across as a 'WELL ACKSHUALLY' type asshole lol (sorry if I still do!!):
What makes making something like this so insanely difficult (specifically the thing in the video) is as you mentioned the fact that your computer model needs to PERFECTLY match the real world object. That means EVERYTHING needs to be made within incredibly precises parameters. Then on top of that, your sensors need to be incredibly accurate. They can't have any slippage, they can't drift, they can't be noisy.
And then even further you need to account for all kinds of mechanical processes in the software that only begin to emerge after testing. For example, the legs flexing under load/stress but not while idled. The feet bending after heavy hits, the sensors slipping due to a sudden unexpected load, etc.
In the world of a video game, ALL of that is gone. Making a little spider mech in a video game is genuinely high school level geometry and algebra (for the most part).
As a final clarification, I'm not downplaying the Factorio devs. The work they've done to optimize that game to make it run so well, is truly incredible. The amount of shit that's happening in the game every frame is obscene, and to have that all work so smoothly and cleanly is fantastic. I think that's where the admiration should be given, they have quite a few dev blogs written about how they got conveyor belts working (efficiently) for example lol.
Also, in case you want 'proof' read about Inverse Kinematics. It's exactly how you accomplish this type of thing. It's the field of math devoted to "I have a robotic arm and it needs to put it's 'hand' here. What angles do all of the joints need to be?". It's an incredibly powerful and fascinating area of math!
Anyway, I hope I'm not coming across as an ass here. This is an area of math/engineering I am personally very passionate about so I just love to talk about it!
Looks like ROS2 to me
They used the "KevinOchs/hexapod_ros" repository as a base.

Going through the design process and not achieving the main objective makes you appreciate all the engineers and builders who came before you. My mind re-explodes when I see the SR-71 and think of all the setbacks and obstacles Kelly Johnson and skunk works over came to make that thing fly. Hold your head up high, I’m sure you learned so much during this project.
Seriously, continue, it's something very nice and you are so close to achieving it, you already have all the necessary knowledge, disassemble the legs and motors and place it on a new sturdy frame if you can.
Not the frame -- the legs are the issue
You should take what you've learned from this project to make a smaller project from the ground up. Rather than use existing parts that were manufactured for a specific purpose, get individual pieces that can withstand the stresses involved. That way, you can perfect the design with far lower costs and scale up for a second or third iteration.
absolutely right
Good idea
This what happens when you have a idea on a whim. Bunch of genius people but too optimistic
I wouldnt do that, as a robotics engineer you want to use prefab modules. There are many things that went wrong here but indeed making a "scaled" version first would have helped identify the control issues. If you try to design/manufacture everything you spend much more time and money. You are better off breaking a few parts instead.
In the end it looks as though the machine was creating incredible impulses when dropping the legs, proper non-linear controllers designed for each leg and different feet design would have probably been enough to make it work. Ie, spring dampers to lower the impact, force control with grabity compensation instead of velocity control and a ball joint at the feet would have probably saved it. But none the less this is an incredibly difficult project and the fact they got so far is a massive win. Great work everyone who was involved, absolutely insane stuff!
that's what i was thinking

Okay it might have not gone to plan. But dude that was so cool. And it actually walked. I’ve been wanting to build or see something like this for years. That’s so cool. And the possibility of it being possible if we find strongest material is just so exciting to think about.
Pretty sure the legs were made of steel. If they were made of titanium or carbon fiber, probably wouldn't have broken.
and this is just a small company compared to other mechanics giants out there imagine if the Hacksmith had a big budget like 25 million $ that would be even crazier
How is this cool lol
Yeah. I imagine this project will likely help someone build a similar mech in the future. Maybe not now, maybe not 5 years, but having the knowledge of the problems that could arise helps massively. Imagine there would be further problems further into development but at least these ones are known now.

I really dig that you aren’t skipping over the failures, but showing how you persevere and learn from them. So often we’re only shown perfect end results and it sets up unrealistic expectations. Showing the hard work and determination is so important
Absolutely thank you for posting this video and don't ever think of it as a failure. Failure isn't making mistakes, it's continuing to make the same mistakes. This project you learned and grew in experience. That is an invaluable lesson to teach our youth. Don't ever give up!
Money! Money! Money!
The amount of failures you guys pushed through is EXACTLY why I love this channel! Keep it up!
Afterall, it is through failure that we learn the most.
This kind of project is just amazing to me. The persistence and effort you guys put into these videos are really what set you above. Keep it up guys much love
Thank you so much for everything you do, your channel got me into engineering, and thanks to y’all, I had the drive to get my ass into a good engineering college. thank you so much.
It's looks like money! It's smells like money! It's tastes like money! It's MONEY!
Hyperman Is That You?!?!
Great job guys 👏🏻 You make wanna be a better engineer 😃
In a world where kids want to grow up and be internet famous now, these kinds of videos will keep those real thinkers’ heads above the water. Thanks for being so innovative in todays world! I’m scared we will lose passionate thinkers like you guys in the next generations.

It's not necessarily people not being passionate, it's what they end up being passionate about.
Your patience and resilience paid in the end. Your guys have inspired me as i work on my mini projects.
Thanks for making this, I hope many other people donate and you can make an even better mech at some point! Keep up the good work
I hope you guys recover from the expenses on this project so you can do more like it!
It's looks like money! It's smells like money! It's tastes like money! It's MONEY!
This was incredible! I'm so glad this did get green lit because inspiring engineers need to see this kind of effort and what you get out of it, even if it doesn't work out as expected. I'm also sure there was a lot of take aways that will transfer to future projects. Please keep up the great work!
