The H2 EDU-BrainCo Revo 3 U21T Dexterous Hand is a high-performance, 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 comprehensive tactile sensing, enabling sophisticated manipulation and haptic feedback for 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 delivers an active grip force of 70N, a maximum fingertip pinch force of 20N, and a whole-hand payload of 20kg (5kg for four-finger payload). With a repetitive motion accuracy of 0.1° and a joint opening/closing speed of 3Hz, this hand offers precise and rapid manipulation. The minimum grasping diameter is 10 mm, and the maximum is 150mm, with five-finger pinching allowing both four fingers and the thumb to touch the palm.

The hand is equipped with a full-palm array tactile sensing system with a range of 0-25N and a resolution of 0.01N, providing exceptional sensitivity for delicate object handling and texture recognition.

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.
