Awesome bot Angus - it's just a pity we didn't fight (except in the rumble)! Even seeing it in person I didn't appreciate how you did the lifting mechanism - that's a nifty design, and a great video as always
I can barely remember the rumble but looks like we had a few good engagements! Great to catch up and I definitely need to try those brushless drill conversions some time, I have so many old gearmotors...
@@MakersMuse I have a question. I'm trying to build my own robot and I have fairly powerful 12V 0.5A motors. I'm trying to find corresponding esc to remote control it, but I can't find any that fit the 12V 0.5A parameters? Do you have a god website to recommend for ESCs?
3rd place is nothing to sneeze at. Building robots to fight each other is a whole new level of engineering difficulty and you tackled that challenge wonderfully! Also mad props for HAND grinding those splines!
This was *such* a fun video to watch! I loved hearing about all the details of your build and the competition. PCBWAY has so many things to offer to help makers these days. Just a fantastic video to watch. I can’t wait for the next installment!
It was honestly great to hear your legit thoughts about PCBway in the video instead of just being sponsored and giving an ad read, it might actually be something I will use in the future, thankyou!
Can't believe you ground that spline shaft by hand & it not only worked, it held up the whole way through too! Really impressive! Excellent work & congrats on 3rd place!
Love seeing videos on this topic!!!!! Please continue to create and share them! After so much time and hinting of your enthusiasm for robot combat, we finally got to see a propper video on it, hope to see more, and any details you improve or move in a new direction with. Enjoy the Sin City Slug Fest, its been great so far! always hoped to get involved in robot combat, its great to see a grassroots bots and see how they were conceived and implemented as the problems are ironed out.
I was there when you fought this thing and I really enjoyed watching it! (So honoured to have my ant make a cameo appearance! Big vert, pink wheels, purple eyes. Can't miss it!)
Looks like lots of fun. Thanks for sharing your adventure with us. It was fun to see the Band Saw too, that is the same one we have in our High School Robotics Lab. One recommendation concerning the bent arm and bolt holes. Fusion 360 has an amazing stress analysis tool. I had to design a robotic gripper at work and weight was a major concern and using a the tool, I could determine exactly where I needed material and where I didn't.
Loved robot wars growing up. Never made it to the live shows but years later managed to go to a touring event and it was amazing. Really enjoyed watching your journey and hope to see more
Seeing amazing walkers and very complex commercial grade robots get obliterated by small DIY machines at these events always seems like a waste but at the same time is super satisfying. I guess everyone knows what they're getting into, but imagine putting weeks or months into a build and then it's destroyed in a way that can't be repaired in the first fight
Great to see some robot videos again, have missed them a lot.. WOW you created a beast there, thanks for the extensive breakdown on the build and techniques used, that was really interesting stuff.. Those battles looked epic and congrats on the 3rd place 👌
A tip from an experienced spanner swinger when you have a slightly loose id for a bearing a few center punch hits will help tighten the bore and hold the bearing tight
That's actually how the bearing in my truck's A/C clutch pulley is retained from the factory--a series of punched divots around the circumference of the bore it sits into in the pulley.
This was really cool! Had no idea that Sportsman category exists, that's really cool. The KE weapon meta was getting pretty sweaty, so seeing some alternatives opening up is great to see.
It's why we started it here, the barrier to entry for the unrestricted class was becoming way too high sadly. You either made a boring brick / wedge or invested thousands into a robot that would be potentially obliterated in its first fight. Sportsman fights last longer and still have plenty of entertainment value!
@@moremakersmuse as an australian i'm seriously interested in joining something like this, but i cant seem to find any info online about battle bots here. do you know where i can find more info?
@@the_donz What state are you in? SA, Qld and Victoria have groups with regular events for smaller (150g and 1.3kg) bots, all have groups on F-book. Bigger events with combatants Australia-wide like this used to happen 1-2 times a year but it's been 3 years till this recent one - my bots were getting restless! (sorry if duplicate replies, my first one seemed to get eaten by the algorithms)
That spline shaft! Tedious work, I know from experience, you must be an artist!! I enjoy art and craft projects that take patience and problem solving like that.
I like the lifter Saw Combo, pretty unique take on the saw bot concept. Fun idea (though probably not as practical as the spike), what if added a spatula as the lifter to further add to the Hash Slinging Slasher theme
Great work and thank you for sharing! For the anti tip feet, if you were to put a bearing under each, you wouldn’t end up stuck in place and you could use that mobility to move your opponent to a place they don’t want to be. Cheers!
Having done Vex robotics for a good like 5 years now, this build made a lot of sense to me and I liked how you made it. When you showed how the arm works I was like "yup that's how I'd do it"
Really fun bot and a cool design! My own Beetleweight bot Shrapnel Mine has a similar concept but rather than a rear hinged lifting arm it uses front hinged forks to try and expose the underside of opponents to my saw weapon. I have the same control issues as you though. I just bought a Radiomaster Zorro TX which has potentiometer dials to set the speed of the saw and I can then use a switch to turn it off and on and the 'throttle' to control the arm position (since mine is a servo it's way easier to handle the arm though). For your needs the Zorro has four momentary buttons that may make controlling your arm easier even if it's bang-bang style and you could use a dial for the arm speed as well.
Thank you for making this video! The idea of hand grinding splines... wow. I agree with you that the belt has no defense. So, yea, that needs something to prevent it from being rendered useless after 1 hit. If you must stick with the saw blade design with a "lifter", you should consider a lifter that has at least 2 parallel lifters, perhaps like a fork lift, or maybe upside U shaped (joined at the ends) for more rigidity. I suspect, that 1 lifter, tilts the enemy bots more than it "pulls it up" into the blade., whereas a parallel lifter might give you better leverage. The Locked Rotor Amps / Stalled Amps of a motor tend to be 6 to 10 times more than full load (100% RPM). So, one reason why the controller may be dying might be related to the Amperes being drawn with rapid "on" / "off" cycling. Because that's basically like several 6 to 10 time Max Current hits in a row.
Definitely agree on more of a "fork" design for stability. I was originally going to have a spatula kind of scoop, hence the name, but went with the spike due to time restrictions.
I forgot to mention... that DC motors with big armatures tend to have pretty big spike voltages due to the commutation. Consider adding flyback protection.
@@marcfruchtman9473 Yeah, we suspect that's what killed the esc but it wasn't doing any heavy lifting at the time. I'll most certainly swap to a smaller brushless outrunner for next time if only to save several KG of weight.
@@marcfruchtman9473 . "Flyback protection"? A term I've never heard before. Granted my electronics schooling is 40 years old. I think I understand what you are talking about. When you power any wire coil it builds a magnetic field of energy. (Solenoid or motor winding). Take away that feed to it, the collapsing magnetic field around the coil wants to dump current/voltage to somewhere. You don't want it to go back into the driving circuitry. So you add components to direct it away from there. In the case of solenoids, it's simple, a diode/rectifier to ground. DC motors I can see being tricky because it's not a one way deal like solenoids. Did I get it right?
Thanx a lot showing so much fun stuff. 😂 I mill ~ 8 ton/year of 7075, also called AlZnMgCu1,5 a good choice for max stable parts. 7075 is 550N/squareMM and you never need threaded inserts. I also like in this alloy there in no silicium, so milling cutters last 10 times longer.
When you mentioned how hard it was to control, oh man did I relate to that! I did a lot of FIRST robotics (FTC and FRC) and they can get really complicated to figure out. Normally we set up for two drivers, but once or twice we had to drop to one for some reason or another. And man, did that suck to do!
Angus this rules. Dunno if you remember, but you helped me make a sawblade wedge using a direct drive car fan motor that got obliterated by a vert spinner way back in the day. So glad to see you still kicking arse and scaring off mormon doornockers!
@@MakersMuse yeah mate! Stoked you spotted this! I’m doing great, working in web development, still in Sydney, although the most I’m building these days is a mechanical keyboard haha! Always stoked to see you drop a video :)
Dear Angus and if that's not your name I apologize I saw one of your older videos a while back about g10 as a build plate and I just wanted to thank you for turning me on to the material and it has saved me a lot of heartache in my 3D printing projects PS I love your channel keep up the good work
Wonderful practical examples of when to print and when to CNC with examples. You might want to consider finding out how the current limiting works and design your own as the back EMF might have caused the controller to brick. On the robot, you might want to see if you have a spare channel open so you can add 1 servo to expressly lock the cutting arm and the spike at the lowest setting so you can pinch and lift during combat. It could be as simple as a cam rotated to press a spring loaded pin into the blade arm since you use a U shape around it already. Best of luck with the next round of Combat robot fights.
Well done Angus. I like your way of thinking about modifying the robot. When my wife heard the video playing she thought that you were making a "Wombat Robot" not "Combat Robot"! However as Wombats are tough animals it might not be such a bad idea.
You can make your own HDPE sheets using milk bottles and shampoo bottles. And if you laminate it with aluminium or steel as you said it would be quite a lot stronger and thinner. Great video. Keep up the good work.
I used PCB Way to cnc machine part for my custom motorcycle rear spring compressor.. Did 3D printed prototype first.. Superb quality.. Little slow delivery because some holidays at that time. But can reccomend! :)
Blade motor could be down behind lift motor, drive belt could share the lifting axle with a smaller belt going to the blade motor, regardless of lift angle, sharing the same axle as lift would keep belt tension the same.
3D Printing is completely viable for the smaller classes! We even have a 150g "plastic" class which is similar in spirit to the sportsman class with a very low barrier of entry.
Just a tip from someone who spent some time in a machining hall ;) Use steel wires to jam if able, or consider a copper layer on your armour, it will gall and break teeth on saws at high speed and cause them to fail.
I had NO idea pcbway does cnc work... thats amazing. I almost regret buying a 10 foot CNC now.....almost.... except its fekking cool. What might be nice is for you to have a way for your saw to lock and push with the lifting arm instead of just having it lift and stay in position, because thats now how saws are designed to work. They need some force to move them into material. Another addition would be some thin armor for the belt/motor, just something to give it protection against glancing hits from other saws or things. Nothing amazing, even just a chunk of throwaway 3d printed plastic would work, just something to keep an instant cut to it from destroying it.
Was that Paramount Browns ? EDIT : Nope, you're in Sydney. I bought some Ex-Govt PC's from there years ago for $5/kg 😆 Can we have a LOT more Aussie Combat robot content please ? This video was FANTASTIC 👍
Have you looked at slitting saws? It seems they would be a good candidate for saw blades. They can be had in solid HSS, and they are made for cutting metal.
You should try 3d printing jigs to line up the holes correctly. And also learn GD&T to know the correct clearances and how to communicate that to the manufacturer.
Used to watch Robot Wars here in the 🇬🇧. This is great stuff, was even involved in providing parts for some robots that where on the BBC TV program. Planned a bot to take out a house robot, but due to weight limits was unable to build our design, we wanted to destroy the badly positioned hydrolic controller, so it bled all over the arena.
Man the kinda people at that event sound absolutely awesome I wish I knew spaces like this in Vancouver. Not for robot fighting but with people who are cool and make things!
Forky bois are the best! I've had luck with rigidly mounting my forks so my robot rides on their ends instead of the chassis. It makes it so that more of the weight is distributed on the wheels and I get more grip. It could also really help with your lifter.
I've always wanted to get into robot combat. I have several designs for various weight classes already modeled. My favorite is a double drum super heavy weight.
Nice one! I watched a couple of episodes of Robot Wars (UK) a few years ago, but it got boring fast. The engineering choices and how well they worked, really compelling.

Nothing amazing, even just a chunk of throwaway 3d printed plastic would work, just something to keep an instant cut to it from destroying it.
Was that Paramount Browns ?
EDIT : Nope, you're in Sydney.
I bought some Ex-Govt PC's from there years ago for $5/kg 😆
Can we have a LOT more Aussie Combat robot content please ?
This video was FANTASTIC 👍
Have you looked at slitting saws? It seems they would be a good candidate for saw blades. They can be had in solid HSS, and they are made for cutting metal.
You should try 3d printing jigs to line up the holes correctly. And also learn GD&T to know the correct clearances and how to communicate that to the manufacturer.
Used to watch Robot Wars here in the 🇬🇧. This is great stuff, was even involved in providing parts for some robots that where on the BBC TV program. Planned a bot to take out a house robot, but due to weight limits was unable to build our design, we wanted to destroy the badly positioned hydrolic controller, so it bled all over the arena.
This is a really fun video. Love the smaller robot classes.
I’d love to see a launcher and reatractable cable type bot if that’s possible like a cable net launcher that pull them into a dual saw blade set up
for lifting mechanisms it might also be helpful to make a two pronged design or a wider lifter for more support
Man the kinda people at that event sound absolutely awesome I wish I knew spaces like this in Vancouver. Not for robot fighting but with people who are cool and make things!
this is an i did a thing level bad idea, but done with actual safety. love it!
Forky bois are the best!
I've had luck with rigidly mounting my forks so my robot rides on their ends instead of the chassis. It makes it so that more of the weight is distributed on the wheels and I get more grip. It could also really help with your lifter.
That’s so cool! Which robot is yours?
@@brianboxell Its the red and black wide bot at norwalk that got eaten by Lynx and that robot that looks just like Lynx.
I've always wanted to get into robot combat. I have several designs for various weight classes already modeled. My favorite is a double drum super heavy weight.
Nice build. It looks like a lot of fun.
Nice one!
I watched a couple of episodes of Robot Wars (UK) a few years ago, but it got boring fast. The engineering choices and how well they worked, really compelling.
