Linker Hand O30

Twenty joints, twenty motors: the Linker Hand O30 is Linkerbot's flagship and fully actuated model, with every degree of freedom driven directly through its own worm gear. The five-finger hand weighs 730 g, is rated for a 30 kg load, grips with 70 N across five fingers, delivers 30 N per finger and 24 N at the thumb, and repeats to 0.2 mm.

Opening takes 0.8 s and the four fingers flex at 2.39 rad/s, about 137 degrees per second. Communication is CAN or CAN FD at 500 Hz, supply 24 to 48 V with 24 V nominal, current 0.4 A static and 1.1 A idle, maximum power 150 W. The maker states neither passive degrees of freedom nor tactile sensing and warns that values depend on the version. Price on request. Target users are humanoid makers and labs.

Inspire announced a similar fully direct-drive concept with 22 motors in the RH5MK1, the Apex Hand claims a comparable load, and within the brand the Linker Hand L20 is the lower-cost alternative.
