Unitree’s new humanoid is a one-minute film. The eight-hour battery is a maximum, and the rest is not published

The H2-X clip, posted on 21 October, shows kicks, a jump off a car and a scene of pushing a child clear. Unitree says the machine is to “serve and guard,” with a maximum endurance of about eight hours. There is no price, no specification sheet, and no statement of what in the film the robot did by itself.

Unitree’s H2-X film, about one minute. The company has not said which moves were autonomous.

Unitree published a film on 21 October of a humanoid it calls the H2-X, subtitled a kung-fu guardian. In about a minute the machine kicks, jumps from the roof of a car, and is shown pushing a child out of a vehicle’s path. The company’s own line, on the film, is that it has “powerful performance to serve and guard you,” with a maximum endurance of approximately eight hours, and that it should be used safely and in a friendly way. That is the whole of the specification that travelled with the clip.

Eight hours is a maximum. Unitree does not say whether that is standing, walking, or the routine in the film. It does not say which of the moves the robot chose and which were driven, or rehearsed, for the camera. A film that includes a child and a moving car is a safety scene someone staged. It is not a record of a patrol. There is no price, no date a customer can order one, and no sheet of joints, weight or compute for the H2-X itself.

The robot it already sells is a different page

The humanoid Unitree does list, the H2, is a separate product. On the company’s site that machine is 182 centimetres tall, about 70 kilograms, with 31 joints, and a battery life of about three hours. The plain version is priced at $29,900 before tax and shipping. None of those figures is stated for the H2-X. A reader who carries the three-hour battery, or the price, across to the new name is guessing. The new film’s eight hours, if it holds, would be a different machine or a different duty. Unitree has not said which.

The useful question is the one the film does not answer. A guardian that can stand for a shift is a product. A guardian that can decide, on a street it has not rehearsed, whether to step in is a different product, and it needs a log: what it saw, what it was allowed to do, and how often it was wrong. This release is the film and a maximum. The log is not in it.
