Features
Features
Precision at every joint: All finger joints support smooth inverse drive for direct reinforcement learning training.
High degree of freedom: Single-hand 20 degrees of freedom (16 active + 4), all 5 fingers independently replaceable
Four-finger side swing ±22°: Better adapts to the curvature of grasped objects, improving grip reliability.
Precision Feedback, Millimeter-Level Control: Dex5-1P Single-Hand Unit with 94 Haptic Sensors. Supports Secondary Development of Dexterous Touch Algorithms.
High Power Density: Hollow Cup Motor, High Power Density Driver, and High-Precision Encoder
Low-damping, small-gap reducer: Micro-gap design places joint pivots closer to the surface for smoother, more fluid grasping and prevents joints from getting caught on objects.
