Unitree Robotics has put its full-size H2 humanoid into a new role. In a one-minute video posted on Wednesday, October 21, the Chinese company introduced the H2-X “Kung Fu Legend Guardian,” a robot it pitches as a bodyguard that can fight off an attacker, lift a car off a trapped person and pull someone out of traffic. Unitree’s own post on X describes “powerful performance to serve and guard you, with a maximum endurance of approximately 8 hours,” and ends with a request: “Please use the robot safely and in a friendly manner.”
What the company has not released matters as much as what it showed. There is no price, no release date, no spec sheet for the H2-X and no statement on whether the machine in the clip was acting on its own, following a script or being driven by an operator.
What the video shows
The clip runs 1 minute 1 second on Unitree’s YouTube channel, where it passed 326,000 views within a day. It opens with the robot kneeing and punching parked cars in a scrapyard, denting the panels, before moving through a set of staged scenes:
- stepping between a woman and a man with a knife, and sending him away;
- smashing through a car door;
- raising the front of a vehicle so a pinned person can be freed;
- pushing a child clear of an oncoming car;
- dropping from a platform about 4 meters (13 feet) high and landing upright.
It closes with a warning against dangerous modifications and unauthorized use, and advice to keep 2 to 3 meters (about 6.5 to 10 feet) away from the robot.
The H2 it is built on
Unitree says the H2-X is based on its existing H2, which it already sells. The figures below are for that base model; the company has not said which of them carry over.
- Height: about 1.82 meters (6 feet).
- Weight: about 70 kilograms (154 pounds).
- Degrees of freedom: 31, meaning 31 separate joint movements the controller can drive.
- Peak joint torque: 360 newton-meters at the legs, 120 at the arms.
- Onboard computing: up to 2,070 TOPS (trillion AI operations per second), with an optional Nvidia Jetson AGX Thor module.
- Price: listed at $29,900.
Torque is a measure of turning force at a joint, not of lifting capacity. A 360 newton-meter knee says nothing on its own about whether a 70-kilogram robot can raise the front of a car weighing well over a ton, which is why the rescue scene is the hardest one to take at face value without more data.
Eight hours of what?
The headline number deserves a closer look. Unitree’s wording is a “maximum endurance” of roughly eight hours, and reporting on the launch notes the figure refers to standing. A robot that stands guard in a hallway draws far less power than one that sprints, kicks or lifts, so eight hours of standing should not be read as eight hours of the action in the video. The company has given no battery capacity and no runtime under load.
For a sense of scale, if the H2-X shares the H2’s $29,900 price, eight hours a day of standing duty works out to about $3.74 per hour of guarding over its first 1,000 days of duty ($29,900 divided by 8,000 hours), before maintenance, charging or any software subscription. That is a rough illustration, not a figure Unitree has published.
Demo or product?
Unitree has a long record of showy demonstrations. In October 2025 it showed its smaller G1 humanoid doing kung fu routines with spinning kicks and flips, and this year it released clips of robots on rollerblades and ice skates. Last month it announced an AI model, UnifoLM-X2-1.0, that it said lets humanoids spar on their own by punching, blocking and dodging. The H2-X fits that line of agility showcases, with more emphasis on strength.
The open questions are practical ones. A machine sold as a personal guard would have to recognize a threat, decide when to step in and avoid hurting the person it is protecting or a bystander, and it would have to clear consumer safety certification in every market where it is sold. Unitree has not explained how the H2-X detects people or makes those decisions.
The launch also comes at a sensitive time for the Hangzhou company, which listed its shares in August 2026 and has since seen the stock fall sharply from its peak. Until Unitree publishes an H2-X specification sheet, the H2’s $29,900 listing and the eight-hour standing claim are the only hard numbers buyers have.
