China's new robot bodyguard does kung fu and lifts a car. Here's what's real.
Unitree's H2-X disarms a knife attacker, smashes a car door and lifts a car off a trapped person, all in one 61-second video. What it proves, what it doesn't, and what the robot really is.
A man with a knife corners a woman. A robot steps in, knocks the knife away and pins him. Then the same robot punches through a car door, lifts the front of a car off a trapped person, and yanks someone out of the way of a speeding car.
That's the new video from Unitree Robotics, a robot company in Hangzhou, China. It posted the 61-second clip, called "H2-X Kung Fu Legend Guardian," to its YouTube channel on October 21, 2026, and it passed 300,000 views in about a day (BreezyScroll, Interesting Engineering). Here it is:

What the robot is
The H2-X is a new version of Unitree's H2, a humanoid robot it first showed in October 2025. The H2 is about the size of a tall man (Interesting Engineering, BreezyScroll):
These are the regular H2's numbers. Unitree hasn't said whether the H2-X is the same.
How does a robot do kung fu? Each joint has a small, powerful electric motor, like the joints in your arm have muscles. A computer tells all 31 motors how hard to push, hundreds of times every second, so the robot keeps its balance while it kicks and spins. Last month Unitree also said a new AI program of its own lets its robots spar by themselves: punch, block and dodge without a person steering them (Interesting Engineering).
What the video proves, and what it doesn't
It proves: the robot is real, the video comes from Unitree itself, and the H2 it's built on is a real robot you can buy.
It doesn't prove the robot could do this for real. It's an ad. The "victims" are actors and dummies, the scenes are planned, and Unitree hasn't said whether the robot was thinking for itself, following a script, or being steered by a person off camera. It also hasn't explained how the robot would tell a real attacker from a man carrying a kitchen knife (BreezyScroll, Interesting Engineering).
The car lift is the biggest question. Lifting the front of a car means holding up roughly the weight of several grown men, and the robot itself weighs about as much as one. The H2's published arm strength makes that hard to explain, and Unitree hasn't released the H2-X's numbers (BreezyScroll).
The "8 hours" is mostly standing. Unitree says the H2-X can last about eight hours, but its own caption ties that to standing still, not fighting. The regular H2 runs about three hours on its battery (BreezyScroll).
Even Unitree says keep your distance. The video ends with a warning against dangerous changes to the robot and unauthorized uses, and Unitree tells people to stay at least 2 to 3 meters away, about 8 to 10 feet (Interesting Engineering).
