Unitree H1 Timeline

A specially modified H1 unit (with head and hand components removed) hit a peak instantaneous speed of approximately 10.1 m/s during a 100-metre sprint demonstration. Multiple outlets reported this as a humanoid robot speed record, though Unitree itself noted possible measurement error. The demo was tied to a Beijing humanoid half-marathon event.

Sixteen Unitree H1 humanoid robots appeared in a co-ordinated performance during China's Spring Festival Gala broadcast. Unitree described this as the world's first large-scale, fully AI-driven, fully automated cluster humanoid robot performance, significantly raising the robot's mainstream visibility.

Unitree's official product page and developer documentation began presenting the H1 and H1-2 as distinct configurations. The H1-2 upgraded the ankle from 1 DoF to 2 DoF, increased arm DoF from 4 to 7 per arm, and added optional support for up to three NVIDIA Jetson Orin NX compute modules. Total weight increased from ~47 kg to ~70 kg.

By early 2024, H1 had become widely known for its standing backflip demonstration. Unitree claimed it was the world's first full-size, electrically driven humanoid robot to complete a backflip in place. SCMP reported the robot had reached iteration 4.0 by this point.

Unitree showcased H1 at the World Robotics Congress 2024, highlighting its dynamic locomotion capabilities and positioning it alongside the company's quadruped robots (Go2, B2) as part of a broader product ecosystem.

Unitree Robotics unveiled the H1 as its first full-size universal humanoid robot. Standing approximately 180 cm tall and weighing ~47 kg, it was positioned as a highly cost-effective humanoid with a retail price below US$90,000. Unitree stated the robot was developed in roughly half a year and entered mass production shortly after launch.
