Moss v1 Robot Arms

Moss v1 is an affordable, easy-to-assemble robot arm design for teleoperation applications. Built around Feetech STS3215 bus servos in a 6-DoF leader/follower configuration, it predates and has largely been superseded by the SO-100 arm but remains a supported low-cost option for the LeRobot stack. The public repository currently exposes source visual evidence only for SO-100 gripper parts, so Motari does not claim a complete Moss arm render.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A limited/simplified source 3D asset is available from so_100_gripper_parts/Print_Follower_SO_ARM100_08k_Gripper.STL.
• 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.
