22.3 mph. Unitree’s H1 humanoid just clocked 10 m/s in a straight sprint — roughly 80% of Usain Bolt’s peak. The previous humanoid speed record? 3.3 m/s. Tripled in one demo. The April 11 video racked up 1,500+ likes on Twitter and 150+ upvotes on r/robotics within hours.
The Hardware
180 cm tall, ~62 kg, 0.8m legs, 26 degrees of freedom. M107 motors push 360 N·m peak knee torque. The running gait is pure reinforcement learning — trained in simulation, deployed straight to hardware. No motion capture, no hand-tuned controllers. At 10 m/s, dynamic balance comes entirely from the learned policy. 864 Wh hot-swappable battery. 3D LiDAR and depth cameras for perception. Starts around $90K.
Programmable via SDK
unitree_sdk2 gives you C++ and Python APIs over CycloneDDS, fully ROS 2 compatible. Control locomotion, read IMU and joint states, stream LiDAR — all through code. If you’re building on the humanoid foundation model stack, the H1 is one of the few platforms you can program end-to-end without touching firmware.
