The WUJI Hand is a 20-DoF independent robotic hand designed for high-dexterity humanoid manipulation.

WUJI Hand

The WUJI Hand by WUJI TECH is a human-sized, high-dexterity robotic hand built for real-world manipulation.
With 20 active DoF (4 per finger), self-locking direct-drive micro-joints, and 1 kHz control across 20 axes,
it combines fine, uncoupled finger motion with practical strength (up to 10 kg static grasp and 15 N fingertip force).
