OpenArm

OpenArm is a fully open-source humanoid robot arm platform from Enactic for contact-rich physical AI research. The official hardware repo remains the manufacturing source, while the official OpenArm docs source publishes the v2 actuator and off-the-shelf BOM tables and the separate openarm_description repo publishes the v2 URDF plus DAE meshes used for Motari rendering. OpenArm 2.0 uses DAMIAO 43-series and DAMIAO 8009P motors; its docs list J1/J2, J3, J4, and J5-J8 actuator groups, MiSUMi off-the-shelf arm hardware, and a hub electrical BOM CSV. Motari renders the pinned OpenArm v2 description URDF from enactic/openarm_description with body, arm, and pinch-gripper visual meshes.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A full source 3D asset is available from assets/robot/openarm_v2.0/urdf/example/v2.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.

Canonical source: enactic/openarm_hardware. Original files stay intact and separately licensed under CERN-OHL-S-2.0; Motari adds a separate, adjacent metadata layer.
