An amusing video of a Chinese martial artist getting kicked in the privates by a humanoid robot has gone viral.
The video first emerged on popular Shanghai-based video sharing platform Bilibili on Christmas Day before spreading like wildfire and garnering many giggles. It shows a man using a motion capture suit to get a robot from renowned manufacturer Unitree Robotics to mimic his movements.
Unfortunately, a delay with humanoid creation’s reaction timing caused its metallic foot to make its way into the Kung fu kickboxer’s crotch as he was working on some questionable-looking shadowboxing. As the camera operator laughs the Unitree G1 model also mimics his pain by crouching. The painful and funny occurrence even caught the attention of Jackass star and comedian Johnny Knoxville.
“I can’t communicate to you how much I love malfunctioning humanoid robots,” he said on Instagram after adding the classic Jackass theme song to the clip. “Even though in this instance wasn’t necessarily its fault it still, adds up to funny!”
The delay causing the robot to strike in such a manner is attributable to the motion capture model being based on a neural network, according to the account that posted the video.
“This delay will gradually decrease as technology advances, potentially reaching as low as 0.1 seconds,” they wrote.
On a separate video showing the martial arts enthusiast working with the Unitree G1 bot, the caption warns that “robots are dangerous, please be careful with your eggs.”
This comical clip arrives at a time when trainers are increasingly using humanoid robots for martial arts practice. In China, organizers also toss them into the ring to battle each other in popular competitions.
Another popular video that emerged online a few weeks ago shows a man getting kicked to the ground by an EngineAI T800 humanoid. His accomplices observing the demonstration thought it was hilarious.
