Unitree’s New Robot Punches Cars and Blocks a Knife. Here’s What the Video Doesn’t Prove

A six-foot robot walks up to a parked sedan and punches a dent into the hood. Later it lifts the front of a car so someone can pull a trapped dummy free. Then it steps between a woman and a man holding a knife.

That is the new video from Unitree, the Chinese company that sells more walking humanoid robots than anyone else. It posted the clip on October 21 under the title “H2-X Kung Fu Legend Guardian.” The pitch is a robot that protects you. The video is impressive. What it leaves out matters more.

What the robot does on camera

The H2-X is a version of Unitree’s existing H2 humanoid, not a brand-new machine, according to the Chinese tech outlet 36Kr. Gizmodo calls it an unreleased variant.

The video opens in a scrapyard at night. The robot jumps onto a car roof, flips down and kicks a door until the glass breaks and the mirror comes off, Humanoids Daily reports. It jumps off a shipping container and off a platform labeled four meters high, about 13 feet, and lands on its feet.

Then come the “guardian” scenes. In a villa courtyard, a man in a black hoodie walks toward a seated woman with a knife. The robot steps in and blocks him with its arms. In another scene it lifts a sedan off a trapped person. In a third, it pushes a child-sized mannequin out of the path of a moving car and gets run over itself, then stands back up. Gizmodo puts that car at about 2 miles per hour.

Unitree says the footage is real and was not sped up. The video also carries the caption “Extreme testing” and the warning “No imitation!”

Nobody has said who was in control

Here is the gap. Unitree has not said whether a person steered the robot by remote control, whether the moves were pre-programmed, or whether the robot decided anything itself. Both 36Kr and Humanoids Daily point this out.

That is the whole question for a “guardian.” Kicking a car on cue is a stunt. Spotting a real attacker in a real kitchen, and not the neighbor who forgot his keys, is a judgment. As Gizmodo puts it, Unitree has not built a robot that can tell a home invader from someone who lost their keys.

The scenes are edited and scripted. They show one take, not how often it works. And the car lift comes with no word on the car’s weight or whether something else was holding it up. Commenters noticed the car looked supported off camera in places, Humanoids Daily reports.

What it costs and when you could get one

Unitree has published no price, no release date and no spec sheet for the H2-X. The one new number is battery life: about eight hours at most, Unitree says. The regular H2 is rated at about three hours, and Unitree has not said how either figure was measured. Humanoids Daily notes the video’s own wording refers to standing time, not hours of fighting.

The regular H2 gives you a sense of scale. On Unitree’s own site it lists at $29,900 before tax and shipping. It stands about 5 feet 11 inches and weighs about 154 pounds (70 kilograms) with the battery. That is roughly the price of a new compact car.

Unitree’s own product page tells buyers to keep “a sufficient safe distance” between the robot and people. The new video asks for at least 2 to 3 meters, about 7 to 10 feet. A bodyguard you have to stand 10 feet away from is an odd kind of bodyguard.

Why a company would make this video anyway

Unitree listed its shares on Shanghai’s STAR Market on August 19, 2026. It has built roughly 18,000 two-legged robots as of July, according to Humanoids Daily. It has also warned investors that people may buy humanoids more slowly than hoped.

A video like this does one job very well: it shows the machine is strong, fast and hard to knock over. That is real progress, and worth seeing. But a robot that guards your family needs judgment, and nothing in this clip shows that. Until Unitree says who was steering, treat the H2-X as a stunt performer, not a security guard.
