The H2 EDU PLUS BrainCo Revo 3 U21 Dexterous Hand is a high-performance, five-finger end effector designed specifically for the Unitree H2 series humanoid robots. This advanced dexterous hand features fully direct-drive, back-drivable joints, delivering exceptional transparency and responsiveness 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 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 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 all fingers and thumb to touch the palm.

The hand is equipped with the Senyun SHF3L wrist camera — a compact, high-performance vision sensor weighing less than 50g with dimensions of 25 x 25 x 33.54 mm. It features an ultra-wide 196° horizontal field of view and delivers 1920 x 1536 resolution at 30 fps with an RGGB sensor and built-in ISP. The camera supports YUV422 8-bit output and is compatible with NVIDIA Jetson AGX Thor, operating in temperatures from -40°C to +85°C.
