SO-ARM101 Pro Assembled Kit, Leader and Follower Robotic Arms
Shipping: because of its size and weight, this item is not included in the free shipping offer. Shipping is calculated at checkout.
This kit gives you a fully assembled pair of SO-ARM101 arms: a leader arm you move by hand and a follower arm that copies it. That setup is how you record demonstrations for imitation learning in Hugging Face LeRobot. It is an open-source research and learning tool for adults and classrooms, and it needs a computer to run.
What you can build
- Recording teleoperation data for imitation learning
- Training ACT or Diffusion policies in LeRobot
- Pick-and-place experiments
- University and lab robotics courses
