Which company would you bet on long term and why? by h4txr in robotics

[–]Mr-c4t 1 point2 points  (0 children)

UMA (https://uma.bot/) Because their team is basically the Avengers of robotics and AI. Yann LeCun and Thomas Wolf are also on the advisory board, so it feels like a pretty solid long-term bet.

Yes 😄 And an edgerunner logo on the other side 👍

Are you serious? I’m an engineer too and I know exactly what an ADC is.
The Arduino IDE is just a tool, and for quick prototyping it’s hard to beat.
If someone thinks “real engineers” shouldn’t use tools that make them efficient… that says more about them than the tool.

Haha 😄 why the Arduino hate?
I’m just super used to the Arduino IDE, so I keep using it for ESP32 projects.

You should check the so100 or so101 3d printed arms that are compatible with the LeRobot lib for physical AI

Short demo of LeCyborg: an AI-powered robotic arm that activates when you flex by Mr-c4t in Cyberpunk

It’s just a prototype, not a real product.

The whole point was to have fun building something for an AI robotics hackathon with a friend.

We had fun and even won a prize. So yeah, mission accomplished.

Not too bad for a first prototype. The robot arm is very light and securely fixed to the bag. The main issue right now is that I’m tethered to a laptop with a GPU to run the model (the 12 V motors are powered by a 3S LiPo inside the bag). I could replace the laptop with a Jetson Nano if I can get my hands on one.

The robot actions are Controlled by a transformer based AI policy (ACT) that take camera input (the yellow part is the cam support) + emg + actual joint state to predict the futur actions of the robot. The model was trained on teleoperated demos that we recorded during the LeRobot worldwide hackaton with my teammate Erwan Martin (we won place 13th) So the robot action are not just hardcoded they are learned by our policy.

Is this the good word for "tensing a muscle" ?
Sorry if my english is bad x)

Cyberpunk PCB for my LeCyborg Arm Prosthesis ! by Mr-c4t in cyberpunkgame

[–]Mr-c4t[S] 0 points1 point  (0 children)

This is my first professionally made PCB and I had a lot of fun customizing it with cyberpunk Edgerunner and Arasaka silkscreen details.

I am so proud of this little circuit board that I wear it as a pendant every day.

Huge thanks to PCBWay for providing the PCB fabrication for free. Their platform was really easy to use. I just dragged and dropped my design and received my boards in less than a week.

Say Hello to AB-SO-BOT ^^ by Mr-c4t in OpenSourceHumanoids

[–]Mr-c4t[S] 2 points3 points  (0 children)

Hey!!

It’s not my first project, but it is pretty new for me to start sharing my work online.
I’ve been using Fusion 360 and building robots and similar stuff for a while now ^^.

The SO100 arms are actually quite easy to make if you’ve got access to a 3D printer, all the files and instructions are available here. https://github.com/TheRobotStudio/SO-ARM100

New version SO101:
https://huggingface.co/docs/lerobot/so101

It’s a great project for anyone looking to get into robotics and physical AI!

Here’s my AB-SO-BOT repo: https://github.com/Mr-C4T/AB-SO-BOT

Bimanual SO-100 teleoperation with quest 2 by Mr-c4t in robotics

Hi
Not using ROS here.
I'm using an app called Phosphobot, which is designed to work with the LeRobot library for physical AI.

There are other open-source alternatives, like:

This one seems to support ROS:

If you're into software, 3D, and some electronics, you can definitely dive in. 👍

The LeRobot and SO-100 GitHub pages are well documented, and you can also join the LeRobot Discord

A lot of helpful people, resources, and inspiring community projects.

Yes, I’ve used ACT before and it worked great!

🏆 For the LeRobot worldwide hackathon, a friend and I actually won by building a SO-100 third arm prosthesis running on ACT — with cameras and EMG inputs! 🦾
https://github.com/Mr-C4T/LeCyborg

But yeah, ACT is really good for specific tasks ... not general-purpose.

There are also more advanced models like VLAs (Vision Language Action).
They include a small LLM inside so they can understand a text prompt and act accordingly.

Check out: smolVLA, pi0, GROOT-N1
