The 21-kilometre (13-mile) event held in the Chinese capital’s E-Town — a state-backed high-tech manufacturing hub — was billed as a groundbreaking effort to test the limits of bipedal robots in real-world conditions.
At the crack of the starter’s gun, the robots began taking their first tentative steps as the Chinese pop song “I Believe” blared out from loudspeakers.
Curious human runners lined the roadside, phones in hand ready to photograph each machine as it began the race.
One smaller-sized android fell over and lay on the ground for several minutes, before getting up by itself to loud cheers.
Another, powered by propellers, veered across the starting line before crashing into a barrier and knocking over an engineer.
Crossing the finish line first despite a mid-race fall was the tallest droid and one of the heaviest in the competition. At 180 centimetres (5.9 feet) tall and weighing 52 kilograms (114.6 pounds), the metallic black “Tiangong Ultra” finished in two hours, 40 minutes and 42 seconds.
The men’s and women’s winners, both from Ethiopia, finished in one hour, two minutes and 36 seconds, and in one hour, 11 minutes and seven seconds respectively, according to state media.
Tang Jian, chief technology officer of the Beijing Humanoid Robot Innovation Center which developed “Tiangong”, told reporters the company was “very happy with the results”.
“We collected real-world running data from professional athletes and trained the robot so that its gait, cadence, stride length, and various postures could match those of professional runners as closely as possible.”
The Beijing Humanoid Robot Innovation Center, first established by the government, is now owned by Chinese tech firms Xiaomi Robotics and UBTech Robotics as well as two state-owned companies, according to business data provider Tianyancha.
Enthusiastic onlookers cheered the robots on from the sidelines.
“My daughter… got up really early and asked to come watch the robot marathon,” spectator Huang Xiaoyu told AFP, holding her child.
“It was quite a breathtaking experience — we were able to see some of the most cutting-edge robots in our country.”
