Unitree H2-X can fight, jump and lift a car, but could it really become a bodyguard?
Chinese robotics company Unitree has unveiled the H2-X humanoid robot in a demonstration video that looks more like an action film than a conventional technology presentation. The robot performs martial arts moves, jumps from a height of four metres and lifts the front of a car in a rescue scene. Its manufacturer sees it as a future security and rescue robot, but its actual autonomy remains to be proven.
31 joints and up to 300 Nm of torque
According to Unitree's official specifications, the H2-X is approximately 173 cm tall and weighs at least 65 kg including its batteries. The robot has 31 degrees of freedom, allowing it to perform complex movements and maintain its balance.
Maximum torque reaches 300 Nm at the leg joints and 150 Nm at the arm joints. The arm's maximum instantaneous load is approximately 15 kg, or 7 kg during continuous operation.
The robot uses a depth camera and a wide-angle camera to monitor its surroundings. Its two replaceable batteries have a combined capacity of 1.152 kWh. Unitree claims up to eight hours of operating time, although energy consumption depends heavily on the intensity of its movements.
An action film is not proof of autonomy
In the video “Kung Fu Legend Guardian”, the H2-X demonstrates combat moves, stops a staged attack and assists in a rescue scene depicting a person trapped under a car.
However, Unitree has not explained which actions were performed autonomously and which may have involved pre-programmed movements or remote control.
This is an important distinction. Performing a complex movement under controlled conditions does not in itself mean being able to assess a dangerous situation independently and intervene without harming a person.
Prices start at around €22,000
Unitree's official price list puts the H2-X at $25,400, or approximately €22,000, before taxes and shipping costs. The price of the H2-X EDU, intended for developers, depends on its configuration.
The manufacturer envisages uses for the robot in security services, industry, commerce and household tasks.
In Europe, the deployment of such robots depends primarily on meeting safety requirements. Autonomous operation in close proximity to people will be particularly challenging.
The H2-X shows how rapidly humanoid robots' mechanical capabilities are advancing. The next major challenge, however, is not jumping higher or striking harder, but the ability to make safe, reliable decisions independently.
