Linker Hand O20
High-Speed Direct-Drive Dexterous Hand for Industrial Automation
The Linker Hand O20 is a 16-degree-of-freedom dexterous hand featuring full direct-drive architecture. Each of the 16 joints is independently powered by a self-developed brushless motor module — delivering sub-millimeter repeatability and 1000Hz CAN-FD real-time control without the nonlinear friction or backlash inherent in linkage or tendon systems.
Despite its compact 888g form factor, the O20 delivers a 36 kg rated payload with an efficient 0.27A static power draw. The 0.88-second full open/close cycle makes it ideal for high-throughput pick-and-place, while the integrated 6×12 piezoresistive tactile sensor array provides force feedback for delicate operations like connector insertion and fragile component handling.

What Makes O20 Different
The O20 combines direct-drive precision with 1000Hz high-speed control for demanding industrial applications.
Precision Position Control
Closed-loop position control on all 16 joints using self-developed brushless motor modules. Smoothly executes pre-set trajectories from full-hand movements to individual joint micro-adjustments. Ideal for precision assembly and path-following operations.
Adaptive Speed Control
Finger movement speed adjusts dynamically to task requirements. High-speed mode maximizes throughput for grab-and-place workflows; low-speed mode ensures safe, precise operation for delicate tasks. Balances efficiency with safety across diverse scenarios.
Real-Time Haptic Feedback
Fingertip sensors perceive and control force and torque in real time. Dynamically adjusts output force to prevent damage to fragile objects while avoiding slippage from insufficient grip. Critical for screw fastening and thin-sheet handling.
Online Firmware Upgrade
Supports online firmware updates via host computer, enabling continuous iteration of functional modules and optimization of core performance parameters. Designed for industrial and research scenarios requiring long-term upgradeability.
Where O20 Excels
The O20's 1000Hz control loop and 36kg payload make it ideal for high-speed industrial applications.
3C Electronics Manufacturing
0.2mm repeatability with 1000Hz control response makes the O20 ideal for high-speed PCB handling, connector mating, and small-component placement on electronics assembly lines.
Automotive Parts Assembly
36kg payload capacity with force-controlled grasping enables handling of heavy automotive components while maintaining the finesse needed for connector insertion and small-part fastening.
Aerospace Manufacturing
200K sensor cycle lifespan and 24/7-rated operation suit aerospace production environments requiring both delicate handling and robust gripping in complex assembly workflows.
Logistics & Parcel Sorting
0.88s open/close time with adaptive speed control enables rapid throughput for sorting irregularly shaped parcels. Speed-adaptive modes maintain grip integrity on variable objects.
Academic Research & Sim2Real
The direct-drive architecture's deterministic motion model makes the O20 an excellent platform for dexterous manipulation research. Train in simulation, deploy on hardware with minimal domain gap.
Humanoid Robot Integration
888g weight at 36kg payload offers an exceptional payload-to-weight ratio for humanoid robot end-effectors. M3 flange interface enables rapid integration with standard robot arm mounts.
