The Unitree G1 EDU Ultimate B (U4) is a next-generation research humanoid engineered for advanced research, intelligent automation, and high-precision manipulation. It is equipped with two Dex3-1 force-controlled three-finger dexterous hands fitted with tactile sensors as standard, adding touch feedback for refined, human-like interaction and adaptive control across complex tasks. Each joint is monitored by a dual encoder for precise movement tracking, and a local air-cooling system sustains performance under load. Computation is handled by an NVIDIA Jetson Orin NX 16GB (100 TOPS) AI module working alongside an 8-core high-performance CPU, providing dual-tier processing for real-time robot control and neural-network inference. Sensing includes a LIVOX MID-360 3D LiDAR, an Intel RealSense D435i depth camera, a four-microphone array, and Wi-Fi 6 and Bluetooth 5.2 connectivity.

Built on the standard G1 frame, the U4 stands 1320 x 450 x 200 mm and folds to 690 x 450 x 300 mm at approximately 35 kg with battery, so research teams can move it between laboratory spaces, conference venues, and demonstration sites in a standard equipment case. Its 43 degrees of freedom span six per leg, seven per arm, three at the waist, and seven active DOF per hand, with extra-large joint ranges that Unitree highlights for athletic dynamic behaviors. An aluminum-alloy frame with ABS/PC panels and a full-joint hollow design routes power and communications internally for durability and reduced snag risk. With integrated tactile sensing, the Dex3-1 hands support thumb-opposed precision and tripod grasps, secure power grasps on cylindrical and spherical objects, and lateral key grips — a manipulation set suited to demanding industrial and research work. A quick-release 9,000 mAh battery provides approximately two hours of operational runtime.
