Unitree H2

The Unitree H2 is a 182 cm tall, 70 kg humanoid robot with 31 degrees of freedom, high-performance torque motors, 360 Nm of joint torque in the legs and 120 Nm in the arms. Designed for research, education, and future industrial applications. [ unitree.com ]

The Unitree H2 represents the latest generation of full-size humanoid robots from Unitree Robotics and marks a significant technological leap over previous models like the H1. Standing 182 cm tall, weighing 70 kg, and boasting a total of 31 precisely calibrated degrees of freedom, the H2 is designed to replicate human movements as realistically as possible. In official demonstrations, the H2 displays impressively fluid movements, including dance and martial arts sequences, as well as 360-degree kicks, highlighting its exceptional agility and advanced balance.

The robot's structure is constructed from a combination of high-quality materials such as titanium alloys, aircraft-grade aluminum, and high-strength engineering plastics, ensuring an optimal balance between robustness and weight. The internal drive systems are based on high-speed PMSM (permanent magnet synchronous motors), offering an outstanding power-to-energy-efficiency ratio. Of particular note are the 360 Nm of joint torque at the legs and 120 Nm at the arms, enabling the H2 to handle demanding dynamic movements and short-term high-force applications. [ unitree.com ]

The H2 was designed as a platform for research, education, and future industrial applications. Its modular design and high movement precision make it ideal for human-robot interaction, AI-supported motion research, and dynamic testing scenarios in advanced robotics labs. Its two bionic hands enable fine motor interactions, while its stable gait and flexible hip/torsokinematics allow for a wide range of human-like movements. An integrated binocular camera system with a wide field of view, a microphone array, and speakers enable natural interaction via speech and gestures. [ unitree.com ], [ aparobot.com ]

The Unitree H2's computing platform includes an Intel Core i5 in the base version, while the EDU version additionally features an Intel Core i7. Optionally, the robot can be equipped with the NVIDIA Jetson AGX Thor (2070 TOPS), making it an AI-capable platform capable of calculating complex perception and control models in real time. The H2 supports over-the-air motion updates (OTA), meaning that motion algorithms can be continuously improved via the network without requiring any physical intervention. [ unitree.com ]

With a battery capacity of 0.972 kWh and a runtime of up to 3 hours, the H2 offers sufficient energy reserves for demanding interaction or movement tasks. Thanks to WiFi 6 and Bluetooth 5.2, communication is fast and reliable – an essential feature for modern humanoid platforms used in a variety of scenarios. [ unitree.com ]

The Unitree H2 is also remarkably price-competitive: at $29,900 (plus tax and shipping), it is one of the most affordable fully functional humanoid robots in its class and makes advanced humanoid technology accessible to a wider range of research institutions, universities, and innovative companies for the first time.
