- 16 active DoF linkage design Sixteen independently actuated axes in a linkage transmission architecture provide broad grasp posture coverage with coordinated finger synergies and high mechanical robustness.
- Multimodal sensing suite Configurations support fingertip tactile sensing, multi-axis wrist force/torque sensing, and optional visual-tactile perception for slip detection, delicate grasping, and data collection.
- EtherCAT and CAN bus interfaces Industrial fieldbus connectivity supports real-time control integration into humanoid platforms and automation systems alongside CAN-based development and debug workflows.
- Full ROS SDK with simulation support Published ROS launch files, joint state topics, command interfaces, GUI sliders, and PyBullet simulation hooks reduce integration time and support reproducible research workflows.
- Qt application and secondary development Qt-based tooling and an open SDK architecture enable teams to build custom applications on top of the core driver for specialised automation or research workflows.
- Aluminum-alloy construction at ~1.0 kg Lightweight alloy housing keeps the hand mass manageable for humanoid and cobot integration while providing the structural rigidity needed for repeatable manipulation.
Description
The Linkerbot Linker Hand L20 Pro is a five-finger anthropomorphic hand designed for humanoid robots, collaborative robot arms, and lab automation rigs where high degrees of freedom and multimodal sensing are needed for embodied AI experimentation and flexible automation. Linkerbot's L20 uses a linkage transmission that couples certain joint motions to create coordinated flexion patterns similar to common human grasp synergies, with 16 active degrees of freedom in the published motion model. The linkage approach improves mechanical robustness compared to purely tendon-driven designs and reduces cable tuning demands without sacrificing the range of grasp postures required for contact-rich manipulation.
Sensing configurations can include fingertip tactile sensors, multi-axis force sensing at the wrist, and optional visual-tactile perception upgrades using fingertip or palm cameras—making the L20 Pro suitable for tasks such as delicate grasp stabilisation, slip detection, and imitation learning data collection. Control is delivered via CAN bus or EtherCAT with ROS and Qt application support, and a published ROS SDK provides launch files, joint state feedback topics, command interfaces, and example tooling including GUI sliders and PyBullet simulation hooks. At approximately 1.0 kg in an aluminum-alloy housing, the L20 Pro is engineered for humanoid platform integration and research workflows requiring a high-capability general-purpose hand.
