Linker Hand O6
The World's Lightest Industrial-Grade Dexterous Hand
The Linker Hand O6 is a high-precision bionic dexterous hand built for the market's demand for cost-effective industrial solutions. With 6 active + 5 passive joints and a linkage transmission system, it delivers industrial-strength performance in an ultra-compact package weighing just 370 grams.
Despite its miniature form factor, the O6 delivers a class-leading 50 kg maximum payload and 70N five-finger grip strength — powered by self-developed high-torque servo motor modules with worm gear transmission. The force-position hybrid control algorithm achieves ±0.2mm repeat positioning accuracy, making it suitable for both heavy-duty grasping and precision assembly tasks.
Available in 7 colors (Pearl White, Obsidian Black, Tech Silver, Amber Orange, Aurora Blue, Golden Amber, Stellar Purple) and compatible with ROS/ROS2 via open-source SDKs, the O6 offers unmatched flexibility for system integrators.

What Makes O6 Different
The O6 prioritizes strength, compactness, and cost-effectiveness — ideal for industrial deployment at scale.
High-Torque Servo Drive
Self-developed high-torque servo motor modules with worm gear transmission achieve exceptional drive efficiency. High rigidity combined with powerful gripping force — 50kg payload from a 370g package.
High-Precision Control
High-precision servo rigid linkage transmission system with optimized force-position hybrid control algorithm. Achieves ±0.2mm repeat positioning accuracy for reliable, precise movements in every cycle.
Ultra-Compact Design
Innovative materials enable an ultra-lightweight 370g design. Integrated drive-control servo modules result in a compact structure matching human hand size — ideal for collaborative robot arm integration.
Online Upgrade & SDKs
Online firmware updates via host computer. Open-source ROS, ROS2, and Python SDKs available on GitHub for seamless integration into existing robot control stacks.
Where O6 Excels
The O6 is purpose-built for industrial scenarios demanding high strength and low cost.
Logistics Handling
50kg payload with 70N grip force makes the O6 ideal for parcel sorting, warehouse picking, and heavy object handling. Ultra-light 370g weight minimizes robot arm payload consumption.
Industrial Assembly
±0.2mm repeatability with force-position hybrid control enables reliable part placement and fastening operations. Cost-effective enough for multi-unit production line deployment.
Irregular Object Grasping
5 passive joints with bionic elastic damping adapt to object contours, reducing workpiece damage while maintaining grip stability on irregularly shaped items.
Collaborative Robot Integration
370g weight and M3 standard flange interface enable seamless integration with collaborative robots and service robot systems. CAN/RS485 dual protocol support simplifies electrical integration.
