G1-D Ultimate

G1-D Ultimate is Unitree's wheeled dual-arm platform for robotics development, data collection and manipulation training. A lifting column supports a head, articulated waist and two seven-joint arms, while a differential-drive base moves the robot between work locations. Unitree supplies data-acquisition and training tools alongside the hardware, with development interfaces for integrating robot controls and perception.

The Ultimate configuration combines chassis LiDAR and depth cameras with a head stereo camera and wrist cameras. Developers can choose different grippers or dexterous hands and add computing modules for their workloads. Unitree specifies approximately six hours of battery operation and a posture-dependent arm payload of about three kilograms. This mobile configuration is separate from G1-D Standard, which lacks the listed powered chassis, and from the walking G1 humanoid.
