Features
Small yet Dextrous: 1:1 Scale Real Hand – As the dexterous hand approaches human size, it can perform more complex and precise tasks.
22 DOF: Enhanced degrees of freedom for a more comfortable and stable grip angle
Drivers: All 22 motors support direct drive, reverse drive, and dual encoder control. A new roll degree of freedom for the little finger has been added, significantly enhancing the dexterity of the whole-hand grasp.
Extreme impact protection: The impact protection structure safeguards the gears from damage when joint motors are subjected to extreme external forces. All 22 degrees of freedom are protected.
Strength: Single-hand load up to 2 kg; continuous operation load up to 1 kg
3 Interfaces: Supports 15V–65V wide voltage range, Gigabit Ethernet port, USB, and optional high-speed 485; the palm camera can connect directly to the dexterous hand under Gigabit network configuration.
