Unitree Dex2/5 is a compact five-finger tendon-driven dexterous hand designed for humanoid manipulation and embodied-AI research. It weighs 365 g and provides 10 degrees of freedom, including two actuated degrees of freedom, with gear-tendon rope transmission and hidden internal wiring. RS485 communication, joint-state feedback, 24–60 V operation, a 0.5-second minimum fist-clench time, and compatibility with Unitree G1 and R1 support integration, grasping, and repeatable laboratory evaluation. Its listed communication rate and fatigue-cycle testing further suit long-term operation.
