Unitree H2-X

Unitree H2-X is a full-size humanoid robot from Unitree Robotics, marketed under the name “Kung Fu Legend Guardian” (功夫传奇) for security and patrol work, with personal-protection and rescue scenes in its launch film. Unitree’s own page lists security, industrial, commercial and home services as applications. It is a variant of the H2, the full-size humanoid Unitree launched in October 2025. Unitree’s product page lists the H2-X at US$25,400 before tax and shipping, with a developer-focused H2-X EDU version sold through its sales team.

Unitree revealed the H2-X on 21 October 2026 with a short promotional film rather than a datasheet. The film shows the robot throwing flying kicks, knee and elbow strikes, spinning kicks and backflips. It dents car doors and panels, lifts the front of a car to free a trapped person, jumps from a platform about four metres high and rolls out of hard falls. Staged scenes show it stepping in front of its owner during an attempted robbery, disarming a knife-wielding intruder and pulling a pedestrian clear of an oncoming car.

The specification sheet that followed is more modest than the film. The robot stands 1,725 mm tall, weighs 65 kg or more with its battery and has 31 degrees of freedom: six in each leg, seven in each arm, three in the waist and two in the head. Dexterous hands are not included on the standard H2-X and are optional on the EDU version. Two hot-swappable batteries with a combined 20 Ah (1.152 kWh) give a claimed eight hours of runtime. Unitree lists that figure for both standing and continuous walking, but the reveal coverage reported it mainly as standing time. Sensing comes from a wide-angle stereo depth camera in the head and a wide-angle camera in the chest.

Treat the demo as a capability trailer, not proof of a working bodyguard. Unitree has not said whether the fight and rescue scenes were autonomous or choreographed, or how the robot would detect a threat or decide when to act. There is no public evidence of how it performs in unscripted emergencies. Unitree’s own page describes the robot as having “very strong power”, tells users to keep a safe distance (reported as two to three metres) and to use it with extreme caution, and says it is a civilian product that must not be modified for dangerous uses.
