The H2 EDU-BrainCo Revo 3 U21V Dexterous Hand is a groundbreaking, five-finger end effector designed specifically for the Unitree H2 series humanoid robots. This advanced dexterous hand combines fully direct-drive, back-drivable joints with cutting-edge visuo-tactile sensing technology, enabling unprecedented sensitivity and precision for sophisticated research and development applications.

Each hand features 21 total degrees of freedom (four fingers × 4 DOF, thumb × 5 DOF) with hand dimensions of 215x105x50mm. It operates on a wide supply voltage range of 12-80V with a maximum current of 10A (24V). The hand features five-finger pinching, allowing both four fingers and the thumb to touch the palm, with a minimum grasping diameter of 10mm.

The hand is equipped with a comprehensive tactile sensing system combining full-palm array tactile sensing with fingertip visual-tactile sensing. The full-palm array offers a range of 0-25N with a resolution of 0.01N, while the visuo-tactile system achieves a minimum measurable deformation of just 130μm, enabling unparalleled sensitivity for delicate object handling, texture recognition, and micro-manipulation research.

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