Wuji Hand, the new high-dexterity robotic hand that looks like almost human
A new high-dexterity robotic hand showcases a tendon-free, direct-drive architecture with micro-actuators embedded in each finger. The result is 20 independently controlled joints, strong lifts for a direct-drive system, and far more predictable control with a minimal sim-to-real gap. While the palm shape looks natural, future iterations need richer thumb rotation and tactile sensing to unlock true fine-motor manipulation.
- High-dexterity robotic hand using direct-drive actuation (no tendons) with micro-actuators embedded in each finger phalanx
- ~20 independently controlled joints with simple serial kinematics → cleaner control models and a smaller sim-to-real gap
- Uniform finger lengths likely chosen for manufacturability → deviates from human variation and can affect perfect closed grip
- Sensing stack (base model): motor encoders for position only; no evident pressure/texture tactile sensors yet. Space remains for a future glove/skin with embedded sensing
- Core bet: prioritize a robust mechanical platform and predictable control now; layer advanced sensing later → strong foundations for high-precision teleop and RL-based manipulation
- Where it fits today: manipulation research, industrial/semistructured pick-and-place where predictability beats strict anatomical fidelity; promising path toward richer dexterity with added thumb DOFs and tactile feedback
