The SO‑101 is the next‑generation version of the SO‑100 robot arm, originally designed by the RobotStudio in collaboration with Hugging Face. This kit contains all necessary 3D printed PLA+ structural parts to build the SO-101 leader arm. The leader arm serves as the control mechanism that you physically manipulate to direct the follower arm in a teleoperation setup. This frame kit is ideal for building complete teleoperation systems, replacing existing leader arms, educational demonstrations, or custom robotics projects requiring human input. Mechanical assembly is required. Note that electronics are not included - you can get the compatible SO-101 Leader Arm Electronics Kit separately to create a functional system. Compatible with LeRobot SO-ARM100 specifications.
