Favorite: git clone and start using (or spending a whole afternoon to fix environment issues) Least Favorite: some cool projects (especially in academia)—the results need H100s to replicate...

Good point. I've limited the orders to 20 units for shipping in June and 100 units for shipping in mid July.

Great question. I would say that the first time I assembled a SO-101, it took me about 3 hours to assemble and calibrate everything. This product is largely based on the SO-101. With all the improved designs, let's say it would still t

Design for manufacturing is one thing. I did it a lot when building micro gas turbines in college. Sometimes changing the design or manufacturing process will make it 10x faster to make one while not compromising the performance. The second

Man, I gotta say that I tried really hard to see if I could ship before that, but I failed ;( Chasing suppliers is pretty much like dating: sometimes no matter how hard you try, you just can't make it happen.

Thank you for the suggestions. I hear you. When I was at college, the school system basically only allowed Amazon plus a few industry-specific suppliers. Please allow me to prioritize manufacturing and testing so that I can ship the product

Do you mean that Baxter by Rethink Robotics? https://en.wikipedia.org/wiki/Baxter_(robot) Thank you!

Thank you! Let me know how you like the SO-101 design. If you have complaints, I might be able to find a way to fix it ;)

So true. Every time I solder surface mount components, I always wish I could have a steady hand. Sadly, this arm doesn't have that kind of accuracy. The output shaft of the servos we use has about 1 degree of wiggle room and the mechan

Thank you for catching the mistake. I've updated the video descriptions.

$219 is for the unassembled version $299 is for the assembled version $199 is for the first 20 units of the assembled version $599 was the price before I spent hard hours dealing with supply chains When I was just a hobbyist, I had to pay t

Yeah, safety is an important aspect. The good news is that the servos are not that powerful. Peaking at 3 Nm, with a moment arm of 0.2 m, you get 15 N of force, which is basically equivalent to the weight of three 500mL water bottles. This

Yes yes! Flying an aeroplane has no pause button. You are on your own from taking off to landing. It's a great practice not to panic under stress (I never flew one but I guess racing FPV quadcopters probably has the same feeling)

RC aeroplanes need some practice and a bigger field compared to FPV drones. I think I spent a week flying in simulators and another 2 weeks crashing several times to get a basic hold on it. It's kind of like training a robot foundation

The software is fully compatible with LeRobot's repo. As long as your dataset matches your inference time setup, you are good to go.

by charleszyong 1y ago
The software stack is built around LeRobot. So anything you can run with LeRobot should be able to run with our software. Will do more testing before the official release. Personally, I feel GR00T N1 or ACT is much easier to train and do a
