94 tactile sensors per hand; supports secondary development of tactile algorithms for dexterous hands

High-power density
hollow-cup motor

High-power density drive
and high-precision encoder

Low damping small clearance reducer

Micro-gap design ensures smooth and effortless motion

The rotation axis of joint is closer to the surface, with ultra-small joint gaps.
This enables a smoother and more fluid grasp, preventing joint corners from getting stuck on objects.
