The Unitree G1 EDU Ultimate A (U3) is a research-grade humanoid robot and the first configuration in the G1 EDU Ultimate progression to include actual object-manipulation hardware. Where the U1 and U2 configurations provide locomotion, arm articulation, and SDK access without grasping end-effectors, the U3 adds two Dex3-1 three-finger force-controlled hands that let the robot pick up, transport, and manipulate physical objects. This is the fundamental capability that distinguishes manipulation research from locomotion and human-robot interaction work. Full secondary development is supported through Python, C++, and ROS 2 SDK access, running on an NVIDIA Jetson Orin NX 16GB (100 TOPS) compute platform, with a LIVOX MID-360 3D LiDAR, an Intel RealSense D435i depth camera, and Wi-Fi 6 and Bluetooth 5.2 connectivity for perception and communication.

Built on the standard G1 foldable frame, the robot stands 1320 x 450 x 200 mm and folds to 690 x 450 x 300 mm, weighing approximately 35 kg with battery, so a single operator can store it in a standard large equipment case and transport it to laboratories, demonstration venues, and conference sites. Its 43 degrees of freedom span six per leg, seven per arm, three at the waist, and seven active DOF per hand, while an aluminum-alloy structure with ABS/PC panels and a full-joint hollow design keeps power and communications routed internally for durability and reduced snag risk. The Dex3-1 hands operate under force-position hybrid control, closing to a grasp while limiting force so objects are handled without over-pressuring — well suited to precision pinch, power, cylindrical, lateral key, and tripod grasps in manipulation research.
