About this product

Linker Hand L20 Lite is LinkerBot's general-purpose five-finger hand, combining worm gearing and linkage transmission. Ten active and 10 passive degrees of freedom support grasping, pinching, holding and tool manipulation. The manufacturer describes a compact structure intended to balance load capacity with finger mobility, including precision assembly and light industrial tasks. Its published table lists an 800 g mass, CAN and RS485 communication, a 1.2-second opening or closing time and repeatability below ±0.2 mm. These specifications apply to L20 Lite rather than the higher-actuation L20.
