The The Wuji Hand 2 just dropped — and it's one of the most impressive dexterous robotic hands ever built. In this video, I break down everything: the mechanism design, actuation strategy, controller architecture, and the haptic glove they use for training data collection. What we cover: ✅ 20 degrees of freedom with direct drive actuators at every joint ✅ Why no tendons or cables is a game-changer for sim-to-real transfer ✅ Single-stage planetary gearbox design & torque density tradeoffs ✅ MIT Cheetah-style hybrid control (position + velocity + feedforward torque) ✅ Wuji haptic glove — 534 sensors, 120Hz, 10ms latency ✅ Visualizing the hand in RViz, MuJoCo, and Isaac Sim ✅ How it compares to the original Wuji Hand (v1 vs v2) Why direct drive matters for robotic hands: Unlike cable-tendon driven hands, direct drive eliminates cable creep, simplifies system modeling, and makes force control dramatically more accurate. Combined with a low-inertia, low gear ratio design, the Wuji Hand 2 is built for hybrid impedance control — the same approach that makes quadrupeds like the MIT Cheetah so capable.
