LatviaThe UNITREE G1 Dex3-1 set includes a left and right three-fingered robotic hand designed to work with the UNITREE G1 humanoid robot. Each hand provides 7 degrees of freedom and utilizes 7 miniature brushless joints with force control.
Precise Movement and Joint Articulation
Each Dex3-1 hand features three articulated fingers: the thumb has 3 degrees of freedom, the index finger has 2, and the middle finger has 2. The extensive range of motion of each joint supports complex grasping postures across multiple planes, while fingertip positioning repeatability of ±2 mm ensures reliable, repeatable motions.
Hybrid Force Control and Motor Drives
UNITREE Dex3-1 applies hybrid force and position control for versatile operational dynamics. The mechanical design of each hand integrates 6 direct-drive brushless motors and 1 geared motor using F-1515-108 and F-1515-214 joint modules, enabling precise control of torque, angle, angular velocity, stiffness, and damping.
High-Frequency Communication and Feedback
Operating via a USB 2.0 interface with a communication frequency of 1000 Hz, the system provides real-time telemetry. Sensing feedback covers joint mode, position, velocity, torque, temperature, voltage, current, and IMU data, while internal joint communication runs over High Speed Unibus.
