Linker Hand L6
Speed-Optimized Dexterous Hand for High-Throughput Operations
The Linker Hand L6 is a high-precision bionic dexterous hand that pushes the limits of speed and precision. With a 0.35-second full open/close cycle — the fastest in the Linker Hand family — it's purpose-built for high-throughput industrial applications where cycle time directly impacts productivity.
Featuring 6 active + 5 passive joints with a high-rigidity linkage transmission system, the L6 delivers 28 kg payload at just 607 grams. Independent thumb motion control combined with synchronized four-finger precision actions achieves human-like flexible operation at industrial speeds. The standard 6×12 piezoresistive tactile sensor array provides real-time force feedback at 200FPS.

What Makes L6 Different
The L6 is engineered for speed — with precision and reliability to match.
Rapid Response Performance
0.35-second ultra-fast opening/closing response. Independent thumb motion control combined with synchronized four-finger precision actions achieves human-like flexible operation at industrial throughput speeds — over 10,000 cycles per hour.
Compact & Lightweight
607g total weight with a compact structure (193mm fingertip-to-palm). Seamlessly integrates with collaborative robotic arms, service robots, and various automation systems. Compact size maximizes integration flexibility.
High-Precision Control
High-rigidity linkage transmission with self-developed high-precision joint modules achieves ±0.2mm repeatability. Ensures precise and reliable movement in every cycle — even at maximum speed.
Online Upgrade & Force Control
Online firmware updates via host computer. Real-time haptic feedback with fingertip sensors for dynamic force adjustment — prevents damage to fragile objects while avoiding grip slippage.
Where L6 Excels
The L6's speed advantage makes it the go-to choice for high-throughput industrial applications.
High-Speed Pick & Place
0.35s cycle time enables maximum throughput in pick-and-place operations. 28kg payload handles a wide range of workpiece weights without slowing down.
Precision Assembly Lines
±0.2mm accuracy at high speed makes the L6 ideal for electronics and automotive assembly where both precision and throughput matter.
Logistics & Sorting
Ultra-fast open/close with adaptive force control handles irregularly shaped parcels at sorting-line speeds without damaging package contents.
Collaborative Robot End-Effector
607g weight and standard mounting flange enable rapid integration with collaborative robots. Dual CAN/RS485 protocol support simplifies electrical integration.
