The Wuji Dexterous Hand 2 is a high-performance, five-finger end effector designed for seamless integration with the Unitree H2 series humanoid robots. This advanced dexterous hand features a fully back-drivable, direct-drive kinematic configuration, delivering exceptional transparency and responsiveness for sophisticated research and development applications.

Each hand features 20 active degrees of freedom with a skeleton dimension of approximately 185 x 80 x 40 mm. The grasping configuration supports full opposition capability with lateral movement, and the minimum grasping diameter is 0, enabling versatile and precise manipulation. The hand operates on a voltage range of 16-58 V DC.

With a control frequency of 1000 Hz across 20 axes and MIT Hybrid Force/Position Control mode, this hand delivers precise and responsive manipulation. The EtherNet communication protocol (1000BASE-T) ensures high-speed and reliable data transmission. Performance specifications include a fingertip peak force of ≥15 N, open/close speed of ≥4 times/s, and joint backlash of <1°. The hand also features force sensing with a range of 0-30N and sensitivity of 0.005N.

The package includes a wrist-mounted RGB camera with a 130° diagonal field of view and 1920x1080 resolution, along with a dedicated camera mount, cables, and other accessories.

Important Notes:

• This listing is for a single hand. Typically, one H2 unit is equipped with two dexterous hands.
• When placing an order, please specify whether you require a left or right hand.
