Linker Hand

A dexterous-hand product line from Beijing's Linkerbot, spanning tendon-driven, linkage, and direct-drive designs.

Linker Hand is the dexterous-hand product line from Linkerbot (灵心巧手), a Beijing-based company. According to the company, the line spans anywhere from 6 to 42 degrees of freedom and covers three technical approaches: tendon drive, linkage transmission, and direct drive. The L20 model, for instance, is linkage-based with 21 degrees of freedom, driven by brushless motors paired with precision ball screws; the L30 is tendon-driven, with 22 degrees of freedom. A dexterous hand is the end effector a humanoid robot uses for fine manipulation — more degrees of freedom bring it closer to a human hand, but also make control and data collection harder. Products like this are commonly bought by universities and robotics companies to mount on a robot arm or humanoid, paired with a data glove or VR teleoperation to collect dexterous-manipulation data.

ExampleResearchers mount a Linker Hand at the end of a robot arm and use a data glove to teleoperate it, collecting demonstrations of dexterous tasks like grasping or twisting a bottle cap, then use that data to train a VLA policy.
