About this product

Linker Hand L20 is LinkerBot's advanced linkage-driven hand for dexterous robotic manipulation. Its 21 degrees of freedom comprise 16 active and five passive axes, combining brushless motors, precision ball screws and rigid linkages. The manufacturer positions it for tasks that require coordinated five-finger movement and controlled grasping. The official specification lists an approximately 1.2 kg mass, CAN and RS485 interfaces, and ±0.2 mm repeatability. It is a distinct model from L20 Lite and the direct-drive O-series, with its own mechanism and performance specifications.
