Reportedly, the world's fastest high-DoF hand has been developed by LinkerBot, which also featured at the World Humanoid Robot Games finals.
The Linker Hand L30 is a tendon-driven robot hand with 22 degrees of freedom, 18 of them actively driven and 4 passive. The company pitches it for research, medical assistance and precision industrial assembly.
Cables act as tendons to pull the finger joints, the way tendons move a human hand. LinkerBot pairs them with high-resolution encoders and tendon-tension control, which it says gives the hand ±0.2 mm repeatability.
Speed: full open or close in 0.2 s, finger flexion up to 363.6°/s, thumb flexion up to 450.35°/s
Force: 9 N at each fingertip, 6.5 N at the thumb, 39 N five-finger grip, 15 kg maximum load
Sensing: tactile sensor arrays in the fingertips
Integration: CAN FD and Mini-USB, 500 Hz communication, 24 V DC, 1,192 g
LinkerBot also makes the O6, a smaller linkage-driven hand with 6 active degrees of freedom, a 70 N grip and a listed weight of 360 g. Beijing-based LinkerBot closed a Series B+ round in April at a reported $3 billion valuation.
