Unitree H2 - Full-size humanoid robot for research, development, and Physical AI The Unitree H2 is a versatile family of full-size humanoid robots designed for research, education, AI development, and demanding applications in the field of Physical AI. Depending on the variant, it is suitable for motion research, human-robot interaction, autonomous systems, and grasping and manipulation tasks. With a standing height of approximately 1.82 m, a weight of about 70 kg, and a bionic face, the H2 combines a human-like appearance with high mobility and powerful actuators. The base platform features 31 degrees of freedom, including twelve in the legs, 14 in the arms, three in the waist, and two in the head. The chassis is made of aerospace-grade aluminum, titanium alloy, and high-strength engineering plastic. Industrial cross-roller bearings and low-inertia PMSM joint motors enable precise and responsive movements. The H2 achieves maximum joint torques of up to 120 N·m in the arms and up to 360 N·m in the legs. Standard features include bionic wide-angle stereo cameras, array microphones, Wi-Fi 6, and Bluetooth 5.2. The quick-swap 0.972 kWh lithium-ion battery provides a runtime of approximately three hours. The model family ranges from the demonstration-oriented base version to the development-ready H2 EDU Standard and the H2 EDU Smart variants, which feature various grippers as well as three- and five-finger hands. Depending on the configuration, up to 73 degrees of freedom, tactile or visuo-tactile sensors, wrist cameras, and additional high-compute modules are available.
