Linker Hand L30 Pro
Next-Generation Modular Biomimetic Dexterous Hand
The Linker Hand L30 Pro is the newest flagship in the Linker Hand family — a modular, anthropomorphic dexterous hand that represents the latest advances in tendon-driven robotic end-effector technology. It integrates core breakthroughs in motion control, biomimetic design, and mechatronic systems to faithfully replicate the fine motor capabilities of the human hand.
With 17 independent active joints across 5 fingers (including 1 wrist DOF), the L30 Pro achieves 21 total joints through an "active-passive" cooperative architecture. Active joints deliver sub-millimeter motion control through high-precision drive units, while passive joints use biomimetic elastic structures to adaptively regulate force feedback — absorbing impact and reducing system energy consumption. This design enables human-level dexterity while optimizing dynamic efficiency and structural stability.

What Makes L30 Pro the Pinnacle
The L30 Pro elevates tendon-driven dexterous manipulation with 900Hz control, 39N grip force, and built-in tactile sensing.
Bionic Drive Architecture
Tendon-driven transmission system with remote motor groups enables 17 active DOFs across 5 fingers and 1 wrist in a compact, adult-hand-sized form factor (21 joints total). Each finger achieves 3-DOF anthropomorphic motion, precisely replicating the core characteristics of human hand multi-joint coordination.
High-Precision Force Control
Integrated high-resolution encoders with tendon tension control algorithms and adaptive PID real-time dynamic regulation deliver ±0.20mm repeatability. Reliably executes precision-demanding tasks like screw tightening and thin-sheet picking where force accuracy is critical.
39N Grasping with Adaptive Payload
Opposable thumb configuration paired with independent four-finger force control outputs up to 9N per fingertip and 39N combined grip. High-sensitivity tactile arrays in fingertips enable autonomous object detection and adaptive grasping of irregular objects without manual intervention.
Blazing-Fast Response
Core motion speeds exceed 400°/s on all finger axes, with thumb MCP bending peaking at 450°/s. Complete hand open/close in just 0.2 seconds — purpose-built for high-throughput industrial assembly lines. 900Hz CAN-FD ensures millisecond-level command execution.
Where L30 Pro Excels
The L30 Pro's 900Hz response, 39N grip, and tactile sensing make it the definitive choice for high-end dexterous manipulation.
Advanced Research & Sim2Real
21 joints with full ROM/speed characterization per axis provide a research-grade platform for dexterous manipulation studies. The tendon-driven architecture's biomimetic motion patterns make it ideal for human hand movement replication and learning-based control research.
Precision Assembly
0.5N gripper resolution (via fingertip tactile array), 0.2mm repeatability, and 0.2s open/close make the L30 Pro exceptional for screw fastening, connector mating, and thin-sheet component handling in electronics and automotive assembly.
Medical & Rehabilitation
Tendon-driven passive compliance provides inherent safety for close-proximity human-robot interaction. The 5g-trigger tactile sensing enables gentle grasping suitable for medical instrument handling and rehabilitation assistance.
Industrial Sorting & Logistics
39N combined grip with adaptive object detection autonomously handles irregular, deformable, and fragile objects. 0.2s open/close speed meets high-throughput industrial sorting demands without complex algorithm tuning.
Humanoid Robot Integration
Compact adult-hand form factor (~1200g) with 21 joints and wrist DOF makes the L30 Pro ideal for humanoid robot end-effector applications. M4 flange + XT30 connector enable rapid mechanical and electrical integration.
Embodied AI Data Collection
Built-in 200FPS tactile array captures high-fidelity force/touch data for embodied AI training. Compatible with PyBullet, Isaac Gym, MuJoCo for Sim2Real transfer. 900Hz CAN-FD ensures synchronized multi-modal data logging.
