LINKERBOT Linker Hand L20 Lite 20‑DOF Dexterous Robotic is part of the Linker Hand dexterous robotic hand series for robotic manipulation, education, research, industrial automation, and humanoid end-effector integration.
Linker Hand L20 Lite is the standard high-DOF research model in the guide, built for projects that need richer finger motion, finger splay, and flexible multi-posture grasping without moving to the flagship L30 platform.
This listing is organized as a multi-variant product so the hand side, communication interface, and other available options can be selected from one product page.
Features
- 20-DOF hand platform - 10 active + 10 passive joints support highly biomimetic finger motion and adaptable grasping.
