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—ideal for precise grasping and manipulation tasks.

With a total of 31 degrees of freedom (arms, waist, column, and dexterous hands), the U2 robot offers fine-tuned articulation across its limbs. Each Dex3-1 hand features 7 DoF (thumb: 3, index: 2, middle: 2), integrated RGB camera, and USB communication interface. The hands operate at 12–58V, with low standby current for power efficiency.
