Wuji Hand

A high-DOF dexterous hand designed for contact-rich manipulation teleoperation and imitation learning data collection. 5 fingers × 4 joints, a 24×32 tactile pressure map, IMU, and EMF sensing — rich state for training manipulation policies that generalize.

Built for Teleoperation & Policy Learning

The Wuji Hand provides a rich sensor state representation suitable for training manipulation policies that generalize across grasp types and object geometries.

Contact-Rich Manipulation

16-region tactile sensing plus 20 joint positions give a detailed state for tasks like peg insertion, deformable object manipulation, and in-hand regrasping.

Imitation Learning Data

JSONL frames captured at 30 Hz stream directly to the Fearless Platform episode browser. Export as JSONL for ACT, Diffusion Policy, or any custom pipeline.

Bilateral Teleoperation

Run two agent processes simultaneously — one per hand — connected to the same session for bimanual data collection at full resolution.

Works with OpenArm 101, DK1 Bimanual Kit, and other SVRC hardware.
