Fixed-Base Dual-Arm Humanoid Platform

Unitree G1-D Standard B U2 Humanoid Robot

The Unitree G1-D Standard B U2 is a powerful fixed-base dual-arm humanoid robot designed for advanced research, robotics development, and dexterous task simulation.

This version includes all the core features of the G1-D Standard A U1, while upgrading to Dex3-1 Force-Controlled Three-Finger Dexterous Hands, making it suitable for precise grasping and manipulation tasks.

31 DOF Total degrees of freedom across the complete robot platform

7 DOF Per Dex3-1 force-controlled three-finger hand

100 TOPS NVIDIA Jetson Orin 16G AI computing performance

3 kg Maximum payload supported by each robotic arm

Dexterous Manipulation

Dex3-1 Force-Controlled Three-Finger Hands

Each Dex3-1 hand features seven degrees of freedom, an integrated RGB camera, and a USB communication interface. The hands operate at 12–58 V with low standby current for power efficiency.

7 DOF per Hand

Each hand provides seven degrees of freedom: three in the thumb, two in the index finger, and two in the middle finger.

Three-Finger Structure

The Dex3-1 configuration combines an articulated thumb, index finger, and middle finger.

Integrated RGB Camera

Each hand includes an RGB camera for close-range visual input during object interaction.

USB Communication

The hands use a USB communication interface for connection and control.

12–58 V Operation

The Dex3-1 hands support an operating voltage range of 12–58 V

Low Standby Current

The hands use low standby current for power-efficient operation.

Hand Specifications
