Overview

The Linker Hand L30 is not a complete humanoid machine, but rather a particularly dexterous robot hand from Chinese manufacturer Linkerbot, founded in 2023 by Alex Zhou Yong. It is designed as a component for humanoid robots and demanding manipulation tasks and is considered the company's flagship model.

Design

The L30 is tendon-driven and features 25 joints, of which 22 are active and three are passive degrees of freedom. It weighs approximately 1.4 kilograms and communicates via the CAN FD protocol at speeds of up to 5 Mbit per second. Repeatability accuracy is around 0.2 millimeters, with maximum movement speed of up to 440 degrees per second.

Technology and AI

With this design, the L30 is oriented toward contact-intensive, high-precision tasks whose control approaches and partly exceeds human capabilities. In demonstrations, the hand screws in bolts in seconds, making it suitable for assembly and precision mechanical work.

Market Significance

The L30 is priced from approximately 10,000 US dollars and is thus significantly cheaper than older Western research hands. Linkerbot has established itself as a supplier of dexterous robot hands to leading humanoid manufacturers and industrial companies and has delivered over 10,000 hands according to its own statements in 2025.
