The world's highest-DOF and safest humanoid dexterous hand. Up to 42 DOF with vision-touch fusion, electronic skin, and fingertip cameras — giving robots truly human-level hand manipulation.
The L20 dexterous hand ships a fully open-source ROS/Python SDK with plug-and-play support for UR, XArm, and more — from beginner labs to research projects, helping universities build robot teaching platforms fast.
LinkerBot dexterous hands lead internationally, giving universities the most advanced end-effector platform for robot education and research.
Up to 42 whole-hand DOF (human hand 27 / ShadowHands 26), with up to 7 DOF per finger
Vision-touch perception: fingertip + palm + wrist cameras with full electronic skin coverage
0.01 N 3D force precision and 1 mm resolution — multimodal perception at an internationally leading level
The first web-based dexterous hand — no coding required, two ways to get started quickly
Self-developed flexible joint motors with over 0.1 mm repeatability — the smallest motors in dexterous hands
From entry-level teaching to research, from 6 to 42 DOF, LinkerBot offers a complete product matrix.
A 6-DOF entry-level hand that is low-cost and quick to learn, ideal for classroom demos and basic labs.
A 20-DOF mainstream research model with multi-sensor modules, suited for robot competitions and research.
The L20 lite keeps core functions while cutting cost significantly — ideal for bulk teaching purchases.
25 DOF, close to the human hand (27 DOF), suited for dexterous and fine manipulation research.
A 30-DOF direct-drive model with fast response and high force-control precision for high-dynamics research.
