LINKERBOT Linker Hand L30 21‑DOF Tendon‑Driven Dexterous Robotic Hand is part of the Linker Hand dexterous robotic hand series for robotic manipulation, education, research, indust rial automation, and humanoid end-effector integration. Linker Hand L30 Tendon-Driven is the flagship L30 bionic hand configuration from the guide, built around a 21-DOF architecture for smooth, fast, human-like fine manipulation and high-end research scenarios. This listing is organized as a multi-variant product so the hand side, communication interface, and other available options can be selected from one product page. Features Flagship 21-DOF platform - 17 active + 4 passive joints support highly biomimetic hand motion. Tendon-style bionic drive - The guide highlights L30 for smooth motion, rapid response, and fine human-like operation. Millimeter-level precision focus - The product introduction lists +/-0.20 mm repeatability for precise operation. Multi-modal sensing path - The product introduction lists pressure-resistive sensing as standard and capacitive or visual-tactile sensing as optional paths. High-end application fit - Recommended for high-end research, medical-assistance prototypes, industrial precision assembly, and demanding interaction scenarios.
