Yujin technology launches humanoid-style 7-axis dexterous robotic arm

Yujin Technology has announced the release of its new 7-axis dexterous robotic arm, the R1, priced from 9,900 yuan. The robotic arm features a seven-axis design with high redundancy, enabling human-like flexibility and precision. It boasts a repeat positioning accuracy of approximately 0.1 millimeters, with each joint capable of moving at over 180°/second. The arm has a maximum reach of 650 millimeters when equipped with a dexterous hand and can carry a payload of 2 kilograms. Its compact and lightweight design, weighing just 5.5 kilograms, combines metal and high-strength engineering plastic for durability and lightness. The R1 is designed for easy deployment in laboratories, teaching stations, or small workspaces without requiring extensive setup. It includes force feedback and collision detection, supporting both position and torque control modes for safe human-robot collaboration. The system is built on Ubuntu, with XT30 and CAN485 hardware interfaces, and plans to open-source control programs and interfaces. The end-effector can be quickly swapped to accommodate different tools such as grippers or dexterous hands. Yujin has outlined four main application areas for the R1: research and education, industrial automation, smart interaction and maintenance, and service robotics. The R1 is positioned as a consumer robotics product, with a warning against dangerous modifications. Due to its low gear ratio, the arm's position control stiffness is limited, and users are advised to optimize control strategies for accurate dynamic operations. The product is intended for use in scenarios such as laboratory automation, dual-arm assembly tasks, complex operations on mobile platforms, and simulating daily tasks like coffee preparation.
