Chinese company Unitree has released a short video showcasing the capabilities of its full-sized humanoid robot, the H2-X Kung Fu Legend Guardian. Developed on the basis of the H2 platform, the new model is presented as a technological solution designed for security and rescue operations.

At the beginning of the video, the robot climbs onto a car in a lot filled with old vehicles, performs a backflip, and delivers strikes with its knees, elbows, and fists. The impacts leave substantial dents in the car’s doors and hood. The robot then jumps down from a four-meter-high platform, rolls across the ground, and gets back on its feet. It also performs airborne kicks and various acrobatic movements.

According to Unitree, the video shows actual tests of the robot, and the footage has not been artificially sped up.

The following scenes illustrate potential applications for the robot in security and rescue situations. In one scene, the H2-X stands in front of a woman to protect her from an armed individual, forcing the attacker to retreat. In another, the robot attempts to push a person out of the path of an approaching car and move them to safety. The video also shows the robot lifting the front of a vehicle to remove a mannequin trapped underneath.

Full technical specifications for the H2-X have not yet been released. According to the company, a fully charged battery may provide approximately eight hours of operation. However, this figure likely applies to a moderate level of activity. Walking long distances and performing repeated jumps could drain the battery more quickly.

For comparison, the standard Unitree H2 model operates for approximately three hours on a single quick-swappable 15-amp-hour battery. The new model may therefore use an upgraded battery or a control system with improved energy efficiency.

According to published information, the H2-X is similar in size and weight to the standard H2 model. It stands approximately 182 centimeters tall and weighs around 70 kilograms.

The robot has 31 degrees of freedom. This means it can perform a wide range of movements using numerous independently controlled joints. Each leg has six degrees of freedom, while each arm has seven. The waist has three degrees of freedom, and the head has two.

The H2-X is designed to operate at temperatures ranging from −20 to +60 degrees Celsius. Its frame is made from durable materials, including aerospace-grade aluminum, titanium alloys, and high-strength polymers.

The model also features additional interfaces for developers. These allow them to create custom sequences of movements and configure patrol routes.

The unveiling of the new model reflects growing interest in using humanoid robots not only in manufacturing but also for security and assistance during emergencies. Nevertheless, further information is needed to determine how effective the demonstrated movements are under real-world conditions and whether the robot can independently carry out security and rescue tasks.
