SO-ARM100 / SO-ARM101 (Standard Open Arm)

SO-ARM100 is The Robot Studio's Standard Open Arm follower design, a low-cost printable 6-DoF manipulator used by the LeRobot ecosystem. The Motari visual renders the official SO100 URDF/STL assembly, and the BOM now follows the pinned upstream follower-arm table rather than mixing estimated print costs into the source-listed kit total.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A primary assembly 3D asset is available from Simulation/SO100/so100.urdf.
• Source-backed bill-of-materials evidence is linked with per-part provenance where available. Prices marked estimated are not yet verified against a vendor.
• A transparent reproducibility score so buildability is a sortable, first-class property.
• Cross-links to the source repo, datasets, models, and forks.
