Unitree Dex5-1 Dexterous Hand
Smart Adaptability, Instant Responsiveness
The Dex5‑1 is a cutting-edge five-finger robotic hand offering an impressive 20 degrees of freedom (16 active + 4 passive), delivering ultra-smooth backdrivability that removes the “stiff hand” effect and enables fluid, lifelike motion, especially useful for reinforcement learning tasks.
Its design includes a ±22° lateral swing for the four fingers, which enhances grip adaptability on curved surfaces, and 94 tactile sensors per hand for precise sensory feedback and algorithm development.
High Precision, Ultimate Control
Each finger joint offers multiple degrees of freedom for smooth backdrivability, eliminating “stiff hand” effects and enabling smoother, more convenient operation for reinforcement learning (RL) training.
Ultra-fast Reflexes, Snake-like Flexibility
Degrees of Freedom: 20
Modular design allows independent replacement of each finger.
Four-finger Lateral Swing 22 degrees
Enhanced grip reliability with improved adaptation to the curved surfaces of grasped objects.
Precise Feedback, Control Every Millimeter
94 tactile sensors per hand for precise feedback
Supports secondary development of tactile algorithms for dexterous hands
High-power-density hollow-cup motor
High-power-density drive with high-precision encoder
Low-damping, small-clearance reducer
Micro-gap design ensures smooth and effortless motion
The joint rotation axis is positioned closer to the surface, with ultra-small gaps, enabling smoother, more fluid grasps and preventing joint corners from catching on objects.
