The first "World Humanoid Robot Games" is in the books.
The three-day competition hosted in Beijing wrapped on Sunday, attracting 280 teams from 16 countries, including the U.S. Teams used robots manufactured by Chinese companies such as Unitree and Booster.
During the games, humanoid athletes competed in dance battles, martial arts, track and field events such as the 400-meter and 1500-meter races and long jump, and a soccer tournament.
"Robots have stronger joints and core strength," said Guo Tong, who programmed one of the futuristic footballers for his team, Hephaestus.
Guo said he sees robots replacing his idol, soccer star Cristiano Ronaldo, by 2050.
"Robots are easier to coach," Chinese Olympic boxer Li Yang told CNBC while watching his robot slug it out with another. "Humans are emotional."
Hangzhou-based Unitree, seen as a competitor to Tesla 's Optimus, won multiple medals. Beijing-based X-Humanoid and Hong Kong-listed Shenzhen firm UBTECH also impressed.
