Linker Hand O7 Left – 7-DOF Lightweight Dexterous Robotic Hand with Built-in Tactile Array

• 7 active + 10 passive DOF deliver human-level dexterity in a palm-sized package.
• Built-in 6 × 12 resistive tactile array (72 cells) for real-time force mapping.
• 700 g aluminum-alloy frame handles 5 kg payload; ±0.20 mm repeatability.
• Plug-and-play ROS 2 drivers, CAN / RS-485 interface; ready for UR, Franka, Unitree H1 & more
• ndustrial-grade durability with overload & thermal protection; 1-year replace-not-repair warranty.

Linker Hand O7 is a compact, 7-degree-of-freedom dexterous robotic hand engineered for research, education and light-industrial manipulation. A proprietary linkage drive and in-house joint modules keep weight to just 700 g while preserving powerful, human-like motion (12 N thumb & finger pinch force, 95° thumb yaw, 90° finger flexion).

The standard 72-cell resistive tactile array streams 200 FPS contact data, enabling precision grasp control out of the box. Optional upgrades include 6-axis force/torque, vision-tactile, and full electronic skin modules.

With open-source ROS drivers, sample datasets and ready-made learning pipelines (ALOHA-act, Diffuse Policy, etc.), O7 drops straight into research stacks or industrial cobot cages—no custom firmware required.
