Building Humanoid Robot Arm (part 2)
HTML-код
- Опубликовано: 9 фев 2025
- I have finished the build of the affordable 3D printed robot arm. It has 7DoF, brushless motors and quasi direct drive actuation on all axis. It is highly back-drivable. The size of this arm is similar to the human size, thus it should be great arm for the humanoid robot. So should we build a humanoid with it?
The CAD and 3D printer files will be available through my Patreon page: / skyentific

Open source humanoid robot?
Yes of course we should do this!
Yes please. Cant wait to see open sourced full HR on your channel.
I missed your posts! Keep going and good luck with your projects !
Thank you!
Thank you. Don't stop.
Awesome seeing you again and... If Terminator teaches us anything is that the distance between the shoulders is never to wide.
Ahahaha... Is that what will be built, a Terminator?
really happy to see a video from you! congratulations on 100,000 subs!
Thank you a lot! And thanks for following me!
Thanks for bringing so many talented people together! The comments are a knowledge base on its own already!
Congrats and keep up the good work! 😊
Oh yes. If i had the Engineering skills I'd totally devote my free time to this. I barely started getting into modifying and building 3d printers but I'd happily follow along. Thank you for your work.
Ps : It would be funny if the robot could at any given time drop on the floor and use its 4 appendages with 4 toolheads.
Speaking of which, would this kind of arm be precise enough to be used for 3d printing in space?
Amazing, keep up the good work. I've subscribed via Patreon. Thank you
Thank you a lot.
ayy congratulations on the play button!
Thank you!! 😁
Glad to see you are still active!
good to see you back!
Hello, you are an inspiration! What you propose is the holy grail of the open-source technology world! I have watched your videos for a couple of years now, and I have often wondered if your current path would lead you to this precipice. I say yes, lets dive in!!! I will gladly follow you into this great endeavor!!! Love the content, love your approach!!!
Congrats on the 100k subs. You earned it, great job.
Thank you a lot!
Yes of course we should do this!
Поздравляю с наградой!🎉
Thank you!
Glad you're back! Would be super cool to see this integrated with something like huggingface/lerobot. So far they're only doing pick and place on small objects on a table, but maybe you could pick and place the table instead with that beefy arm 😂
Did you ever get LeRobot to work? Its on my bucket list! 😊
I am a CAD designer who would love to help design the robot. 6+ years of design experience in Fusion 360. Also, have some knowledge of coding robots using ROS.
How's you get ros and cad training? Ros tutorials suck
Ros tutorials do suck, you eventually develop programming and peripheral skills sufficiently to be able to navigate past that hurdle
If you are interested, I have made a discord (I am not sure that we will stay there, but I think it is a good place to start). Please send me an email (you can find it in the RUclips channel description), I will reply to you with a discord link.
@@Hoenhighn1 Self-taught on both. A few guys on RUclips teach ROS, but you will need some understanding of Python, coding, and Linux. Check out Articulated Robotics. I started with reading books on ROS1 years ago and it took me years of fiddling with it on and off to understand any of it. I suggest The Constructs ROS tutorials. You do have to pay for it monthly. But, the classes introducing you to Python for robotics were beneficial for me.
For CAD there are so many tutorials out there. Just pick something you want to design and start. Once you run into an issue, google it and there will 100% be a tutorial showing you how to do it. Keep just plowing your way through it. That's the best way to learn.

Fantastic new designs... Just a little bulky but, I understand strength of material as well. Great Job and thank you for sharing. 😲🙏🤔
Another great robot design video.🎉🎉🎉🎉.
Open-source!!! Obviously is a good idea among makers and tinkerer. I am working with industrial automation system designing & Embedded IOT design field i vote for opensource. And obviously wish to support.

yes , I can build and program the head
Cool idea
Thank you.
YES!!! We should absolutely strive to develop an open source general purpose humanoid. With the number of companies that have almost fully realized that goal, we have plenty of inspiration and reverse engineering to do. I'm confident an open source humanoid is possible, but it would greatly benefit us as makers to have a standard to work off of. If we can all collectively agree on a standardized set of parameters for devloping a humanoid, I'm sure it's a feasible task
This is a great point. I think it would be hard to agree on all parameters, but we can start with something. And if necessary we can always change these parameters during development.
@@Skyentific Yes, the hardest problem with open source projects is that people isn't properly educated to collaborate. For example there are many other robotic arm projects out there but you decide to make yours instead of collaborate with them. Your arm design is too heavy, have too much torque, drains too much energy to work, is too bulky, so in resume is completely inadequate for a humanoid robot. Congrats, you have your OWN project.
yes we should do it
It should be done.
Yes!!!
I like the colour choice , would be perfect at Ikea 😉
Exactly!
Open-source = NOT locked behind a paywall. K-Scale Labs, Anthrobotics, and PointBlankLLC are all truly open-source humanoid projects.
My robot arm is not yet open source. I spent more than 3 month to build it. With zero investors. Spending my own money on this. Now I have exactly zero savings left. And still, I am ready to make it open source if enough people would find the idea interesting and will help.
At least right now everyone can get my design for only 10USD. I looked at the project that you mentioned and I have only found CAD file for K-Scale, and only for there small robot. If I am wrong, please send me the link, I would be glad to check them (you can find my email in the channel description).
Hey, could you give more info on this? Because I did not know any of these yet! I found K-Scale Labs but the other ones do not seem to have a website and or are registered with multiple domains! 😊
I finde your idea to make open source humanoid robot very interesting but also challenging. And I'd like to participate in the project as mechanical designe/production & embedded systems engineer. And I love the colours, they are my favourite! 👍😉

Whats your field? I am also working in automation as a software developer for PLCs 😊
Hello, great ideea. I will be interested in this project. I’ve followed along since you started making gears.
I would be able to help to project on the software side. 5+ years of experience in embedded software.
Good job, and keep up the good work.
Perfect! Software side is something where I need a lot of help. I have made a discord (I am not sure that we will stay there, but I think it is a good place to start). If you are interested please send me an email (you can find it in the RUclips channel description), I will reply to you with a discord link.
Whats your field? And how would you drive the arm? Some embedded real time Linux system might be good, although I guess any up to date laptop will be able to keep up with sending stuff thru the serial or can bus?
Totally agree with you. I can help :)

Let's do it!
top, complimenti! 🦾
yes. you should proceed
OF COURSE WE SHOULD DO IT. I would like to work on the hand part! I think that you/we should start thinking about topology optimization in order to reduce weight and spend less money.

Great idea! I'm in for the project! Actually I already started to do something, I am already tinkering with 3D printed or CNC prototypes, I am trying to do something very easy and cheap, using ESP32, STM32, Rpi etc, with ROS2 and MicroROS. I'm also experimenting with Liquid Neural Networks for the AI part, I have a beefy cluster for training at my disposal. If you are interested let me know! I am 100% willing to release in a free open source, will make some video tutorial too!
This is great! I've heard a lot interesting things about Liquid Neural Networks. It would be interesting to see how it works with robot arm manipulation.

Any website on your project? This sounds super interesting! 😊
I'm very interested in helping to make an open source humanoid robot. Actually it's very exciting to find someone else interested in the same goal. I would be interested in working on the software for the robot's motion.
I’ll build too! Let’s open source it!

great, im designing one too, except it goes on your back and straps to your arm
That's cool! What is application? Or just for fun?
I always wanted to do something like that! Kinda like a cybernetic arm!! 🦾
great idea, I want to participate but I am a junior engineer
Designing an advanced robot arm from scratch and then realizing there are issues with the way it would be held in place feels familiar to me. It's like designing a circuit and then realizing that how it gets put inside a box is a whole huge pain on its own.
Wonderful initiative. I am the author of MachinaScript For Robots, a framework to control robots using Multimodal Large Language Models, so anyone can built Ai-powered robots in their garages. It is basically giving the control of a robotic mount to an artificial intelligence. The project is also openly available on github for anyone to try out, under the apache license.
A question: wouldn't it be more effective to use those MIT cheetah-like actuators for these parts, something like the Atlas 2 is using? Or is it too expensive? I believe for a full body robot these are the best ones, no? 3D printed parts would still be super important, as well as reinforcement learning models for walking, picking things, equilibrium as well as some cognitive reasoning capabilities using LLMs.
I would love to help on the development of the project!
How do you know that Atlas 2 use it? I would be interested to know this for sure. If you have reference please send it to me (you can find my email in the RUclips channel description). And if you are interested in this project I can send you discord link.
MIT cheetah-like actuators unfortunately not cheap. They are becoming less and less expensive, but not cheap yet. Plus, most of them have quite bad drivers. Probably this is why most robotics companies build there own actuators.
I would like to check your project! Any website or github page where I can find it? 😊
Found it!! Thanks a lot!! This is awesome!! 😊
@@swannschilling474 hey swan, a quick google search ober Machinascript For Robots will show everything you need! Github and medium/hackernoom posts all there. 😉 Free the robots!!!
I'm making a mobile robotics platform at the moment. Kind of like mobile aloha but much cheaper.
This is really great! One of the first things, which I want to try with such arms is mobile Aloha. This is really promising technology.
@@Skyentific I think your robot arm will lift more weight than the viperX robot arm. This is one reason why I was interested in your design.
Any github project or website I can check? 😊
Any github page or website on your project that I can check? 😊
@@swannschilling474 hi. I will put instructions, code and bill of materials on my GitHub once I’ve finished filming. Should be around two or three weeks. The frame and motors are from gobilda, the arms I’m using at the moment are hiwonder. Then I have an rpi 5 with a USB stereo camera, an ESP32, four cytron motor drivers and some lithium lipo batteries
oh it's interesting, I'm not sure how I could help, but if I see a way I'll reach out, otherwise count me in for the ride!
i want a robot arm in my kitchen that cooks for me
Mannnnn good job tho i WISH you'd show your process for Making these in fusion, i've been trying to do something similar but am Terrible at fusion
It is complicated to show it. As the design takes a lot of time. And most of the designs I start, and at some point I realise, that I should use another approach. So I discard, and start new design. So for each published design I have 3 or 5 attempts, which I discarded for some reason.
I will follow with interest. I don't think I can add anything to the project though. I'm wondering though about scaling it. Like how much can it lift with approx 10 motors like that in it. But interestingly it would still be interesting at a large scale. Like you never know. 🤔
Hello, I am a college student who is making a robot dog by watching your video. I am currently trying to use odrive v3.6, tle5012b encoder sensor, and steadywin giim8108-8 motor, but I am having trouble with motor calibration. Could you give me some advice on calibration?
My advice would be not to use tle5012b. I had so much trouble with it. Unless, you know exactly what you are doing. I spend too much time trying to make it work. It finally works. But as5048 or as5047p is way simpler.
@Skyentific thank you! I will try it asap
I could not even setup the the as encoder! Is there any tutorial on how to do this? The ODrive 3.6 is pretty outdated but I am also still using it because it us reliable and there are good quality clones out there! 😊
Я думаю, надо добавить вторую руку и научить их завтрак готовить.
This would be perfect.
I love the idea of the open source project, any telegram, discord, slack or any other channel to connect for this?

one practical application for cheap robot arm, yes cheap, easy to make, is to make a two-angle solar tracker, on a arm pole, up high. and needs to be fraction of the cost of the panel itself, say 100bucks for 400W panel. so at most 25bucks to the mounting assembly. or even less say 10bucks. or even less like 5bucks.
Out of curiosity, how much time it took you to design and finish the affordable 3D robot?
For this arm it took around two month for design and around 1 month to assemble.
I think we can keep this crude style for the first prototype of opensource and later optimize more of the stuff, because we want something that we actually have and can call open source humanoid robots instead of just a highly optimized arm. also how do i contribute to it?

какие моторы использовали и какое передаточное число необходимо было добиться? Какой крутящий момент должен быть у двигателя и на конце вала?
I'm concerned on the arrangement of the Noctua fans. They are "facing" each other and they're very close. They're basically fighting themselves. If you flip one around they will work together pulling from one inlet and blowing out the other.
Year, but in this case they would not cool drivers. Right now they blow air through the motors to the drivers. I hope like this they will cool both of them.
Why not use large reduction like harmonic drive?
Im a engineer spezialized on power electronics and software for drives. Im able to design our own open source power electronics to drive each axis of the arm to replace the odrive. We implement open source software for field orientated control, the kinematic model, axis interpolation, path planning,...
If you are interested im available for this Project
Hey, I am still working on figuring out the kinematics of my SPM because I would like to switch to an embedded solution...would you mind taking a look at the project? 😊
How are you going to program the arms ?
Pleas let me know if you have any git library..... As I am also working on arms like this but at a small scale.
First, I would like to do the telepresence demo. This would alllow to check the capability of the arm, without complicated software.
I am in , how do we do this:)
What are the models of these main base engines?
If you ask about brushless motors, these are Multistar 9235 from HobbyKing.

@@Skyentific thanks
I would love to participate
3D printed gears seem kind of silly to me. Isn't it possible to find cheap commercial-off-the-shelf gears with less play and better longevity? Even injection molded plastic gears should be a big step up, and maybe even cheaper than 3D-printed? I also like the idea of using simple sheets of carbon fiber or aluminium in some places (you have used that in some other designs if I remember correctly), they shouldn't be expensive and can greatly increase stiffness I think.
Do it! Upload your design
Your watermark doesn't match your channel name Skyentific!=Skynetific. But maybe that was on purpose? Funny how you check the spelling on the plaque... Anyway, go robot arms - I hope this sparks a robot arms race!

I just reached out via email, I'm very interested in this project of a humanoid open source robot.
What I'm super interested in is not only an open source arm but perhaps USB-C standard wired controllers and Machine learning without weird proprietary garbage. USB-C has PowerDelivery if you need 5,12,20,etc volta whats the discord or whatever?
Good point. Unfortunately, each motor of this arm requires at least 200W of power. The USB-C can only provide 60W. So it is not enough even for a single motor. And it is definitely not enough for the entire arm.
How can I help ;)

Wonderfull idea. why not joim forces with similar youtube channels like: jeremey fielding and James Bruton
Awesome project. Especially thanks for blue-yellow robot 🇺🇦!
i was wondering why so many motors ,?? could this arm be done with almost half the motors??
also a robot head is a bad idea... you can mount a 3d camera in the chest and back also in the arms or hands
robots do not need heads
This arm has 7degrees of freedom. For 7 degrees of freedom you would need 7 motors. This is exactly the same quantity of DoF as in a human arm.
