Made for the current SO-101 workflow
The follower is the actuated arm used for teleoperation playback and autonomous tasks. We pin the upstream source revision used for production, print in PLA+, remove supports and visually inspect the set 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.
Need both arms?
The paired set adds the leader arm used to demonstrate motion and collect training data.
