PincOpen

PincOpen is Pollen Robotics' open-source, low-cost parallel gripper inspired by the Reachy 2 Pincette. The project focuses on 3D-printable mechanical parts, replacing the expensive Dynamixel actuator with a Feetech STS3215 servo, and reducing costly standard components while preserving a versatile two-finger grasp. The repository provides STL and STEP CAD, a public Onshape document with configurations, a public BOM link, an assembly PDF, and motor configuration/flash-test instructions.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A primary assembly 3D asset is available from cad/stl/Bottom_Plate.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.
