Humanoid robots danced hip-hop, performed martial arts and played keyboard, guitar and drums at the opening ceremony of the first World Humanoid Robot Games in Beijing on Thursday evening.

But the robots had other plans. During soccer matches, four mechanical players crashed into each other and collapsed in a tangled heap of metal limbs.

Over 500 robots competed in soccer, boxing, and running. In many cases, gravity was the real winner. This week, China’s leading robotics minds gathered in Beijing for a hotly-anticipated, Olympics-style event dubbed the world’s first “ Humanoid Robot Games. ”

Rock and Robots! A tech company from Hefei, China built a five-member robot band that’s about to debut at the World Humanoid Robot Games, the first-ever international sports festival for humanoid robots.

“The artificial womb technology is already in a mature stage, and now it needs to be implanted in the robot’s abdomen so that a real person and the robot can interact to achieve pregnancy, allowing the fetus to grow inside,” Qifeng told Chosun Biz.
