PingTi Arm
PingTi Arm is an open-source robotic arm built on the SO-100 design with a 600 mm human-scale span and up to 500 g payload at full extension. It uses two STS3250 and six STS3215 serial-bus servos, is compatible with LeRobot via the pingti_lerobot_bridge SDK, and supports a leader-follower setup pairing PingTi as follower with an SO-100 leader. Motari renders the pinned PingTi URDF/STL assembly, and the BOM follows the upstream English source table while separately listing the 12V5A power supply found in the pinned Chinese source table; the mixed USD/CNY source rows are not normalized into a single USD total.

What you get
- A standardized, machine-readable robot schema derived from the source repo.
- A primary assembly 3D asset is available from Simulation/PingTi_Arm_v3/urdf/PingTi_Arm_v3.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.
