Unitree Robotics was founded in Hangzhou in 2016 and made its name with low-cost quadrupeds such as the Go1 and Go2. It moved into humanoids with the full-size H1 in 2023, the smaller G1 in 2024 and the consumer-priced R1 in 2025. The full-size H2 followed in October 2025. Each step pushed the price of a working humanoid lower and built on actuators and software Unitree already made in volume.
The H2-X is the first Unitree humanoid sold under a specific job description. Rather than a research or developer platform, it is marketed for security and patrol, with protection and rescue scenarios in its launch film, and given a name to match: Kung Fu Legend Guardian.
Unitree launched the H2-X the way it has launched several robots: with a short, highly produced film. Martial-arts moves, cars dented with kicks, a car lifted off a trapped person and a staged robbery made for a viral reveal. The detailed specification came afterwards, and its figures are more ordinary: 31 joints, no hands on the standard model, and an arm payload of about 7 kg rated.
That gap matters. A choreographed routine shows what the motors and balance controller can do. It does not show whether the robot can recognise a real threat, tell an attacker from a bystander or decide when to act. Unitree has not said how much of the film was autonomous, and coverage of the reveal flagged exactly those questions.
Most security robots in service today are wheeled patrol units such as the Knightscope K5, built to watch, record and alert rather than intervene. The H2-X pitch goes further, into physical protection. That raises legal and safety questions that a camera on wheels never had to answer, from use-of-force rules to liability if a 65 kg robot injures someone. Our guide to security robots covers what the deployed systems actually do.
Unitree itself is cautious in its terms of sale. It describes the H2-X as a civilian product, warns that it has very strong power, asks users to keep a safe distance and forbids dangerous modifications. Read the bodyguard framing as marketing. On the evidence published so far, the H2-X is a capable, comparatively cheap full-size humanoid platform with a long-life battery.
At US$25,400 the H2-X is listed below the reported US$29,900 price of the base H2, while claiming much longer runtime thanks to its dual hot-swappable batteries. If the eight-hour figure holds up under real patrol work, that is the more important number. Battery life, more than kung fu, has limited how long humanoids can stay on the job.
