Unitree H1 is a full-size general-purpose humanoid robot developed by Chinese robotics company Unitree Robotics. The manufacturer positions it as the first full-size humanoid in China capable of running, with a claimed walking speed of 3.3 m/s and a potential mobility ceiling above 5 m/s.
The robot stands roughly 180 cm tall and weighs about 47 kg. Each leg has 5 degrees of freedom (3 in the hip, 1 in the knee, 1 in the ankle); each arm has 4 DOF in an expandable configuration. Key joints use Unitree M107 permanent-magnet synchronous motors (PMSM), with a peak knee torque of approximately 360 N·m, hip torque of approximately 220 N·m, ankle torque of approximately 59 N·m, and arm joint torque of approximately 75 N·m.
H1 is equipped with a 3D LiDAR and a depth camera, providing full 360° spatial perception. The standard compute configuration combines an Intel Core i5 (platform functions) with an Intel Core i7 (user development), with an optional Intel Core i7 or NVIDIA Jetson Orin NX module for AI workloads. The hot-swappable battery delivers 864 Wh (15 Ah, up to 67.2 V), enabling roughly 2 hours of continuous walking on a single charge.
On the software side, Unitree provides the Unitree SDK2 (C++) and Unitree Python SDK2 as the official development interfaces. ROS 2 and Eclipse Cyclone DDS are supported via adapters, and SLAM / navigation services are available for autonomous behaviour. The robot supports OTA firmware updates and ships with a handle controller for teleoperation.
H1 is positioned as a research and development platform and as the foundation for Unitree’s next humanoid generations (H1-2, H2). This entry describes the base H1 variant; H1-2 is a separate configuration with a higher DOF count, different mass, and updated specifications.
