This is the moment a humanoid robot accidentally kicked an engineer right in the groin during a movement test.

Footage captured on December 24, 2025 in Shanghai, China shows a Unitree G1 humanoid robot mirroring a male engineer as part of a synchronized combat-style demonstration.

Standing directly in front of the machine, the engineer performed a series of martial arts–inspired movements for the robot to imitate, lifting his arms and legs in quick succession.

But as both raise a leg almost simultaneously, the robot misjudged the distance and swiftly booted its handler straight in the groin.

The unfortunate blow sent the man doubling over in pain, while the robot mimicked the bent-over pose moments later.
