Unitree claims 12.66 m/s for a machine three months old — its own H1 was clocked at 3.3

Unitree published a preview of an unannounced bipedal robot on its official channel on 17 August, under the working name "Superman". The description carries three numbers and nothing else: a two-metre standing high jump, a top speed of 12.66 m/s, and a leg length of 0.85 m. The company states the machine "has only been in development for a little over three months, with significant room for further improvement in the coming months", and claims the results surpass the standing high jump and running speed records of all humans. Against Unitree's own line-up, the figure is startling. Our profile of the H1, the humanoid that made the company's name in 2023, records 3.3 m/s as the speed actually clocked, with the maker citing a potential above 5 m/s; the G1 sits at roughly 2 m/s. The new claim of 12.66 m/s works out to 45.6 km/h — close to four times the H1's recorded run, from a machine the company says is a quarter of a year old. What is missing matters as much as what is given. Unitree publishes no mass, no overall height, no actuator or power figures, no price, no availability, and — crucially for a record claim — no test protocol: no surface, no run-up distance, no measurement method for the jump, no indication of whether the results are repeatable or were the best of many attempts. The 0.85 m leg length is the only dimension disclosed. Nor is "Superman" confirmed as a product name; the video is labelled a preview. wujec.ai is not opening a catalogue profile for this machine yet. Our rule is that a preview is not a spec sheet — a launch video routinely mistakes an option for a standard feature, and figures shown before release tend to move. The profile will follow once Unitree publishes a data sheet with a product name behind it. Until then the numbers above are the manufacturer's own claims, reported as such.
