Batch 01 · limited run
The arm inside the cell.
The S1A is the arm we build the S1 cell from. For Batch 01 we are building a limited number of leader–follower kits for research and development teams: robotics and ML groups, labs, and companies building teleoperation and data-collection rigs. Built to order in Germany, shipped worldwide.

The pair we teach the S1 cell with. Move the leader, the follower follows; record with the camera; train with LeRobot or your own stack. Plug into a laptop and go.
The software is open source: a native LeRobot plugin for teleoperation, recording and training, on GitHub. The S1A grew out of our earlier all-printed AIRA arm; Batch 01 is the CNC-supported build.
