Total: 18 shared-geometry pieces + 2 follower-specific pieces + 3 leader-specific pieces = 23. Manifest based on InfiBuild’s pinned production source revision eecbe3e. Gauges, all-in-one reference plates and optional TPU compliant-gripper files are not included.

For teleoperation and learning projects

The leader is moved by a person to demonstrate a task; the follower reproduces that motion. This paired printed-parts product is the structural starting point—not a functioning robot kit. We pin the upstream revision used for production and visually inspect the PLA+ prints before dispatch.

This is an independent fabrication service compatible with the open-source SO-101 design. InfiBuild is not affiliated with or endorsed by TheRobotStudio or Hugging Face.
