Robots ran alongside humans at the Yizhuang half marathon in Beijing on Saturday, April 19.
Twenty-one humanoid robots, designed by Chinese manufacturers, raced next to thousands of runners completing the 21km (13-mile) course.
The winner was Tiangong Ultra, which crossed the line in two hours, 40 minutes and 42 seconds.
Some robots completed the race, while others struggled from the beginning. One robot fell at the starting line and lay flat for several minutes before getting up and taking off.
The race had been billed as the world’s first robot half marathon.
