In a groundbreaking test of robotics endurance, 21 humanoid robots from Chinese manufacturers including DroidUP and Noetix Robotics competed alongside thousands of human runners at Beijing’s Yizhuang half-marathon on Saturday.
The winning robot, Tiangong Ultra developed by the Beijing Innovation Center of Human Robotics, completed the 21km (13-mile) course in 2 hours and 40 minutes—less than half the speed of the human champion’s 1 hour and 2 minutes finish but a milestone for bipedal machines.
Progress Made in Robotic Engineering
The event showcased China’s rapid advances in humanoid robotics. For one, Tiangong Ultra succeeded with long 1.8m (5.9ft) legs and marathon-specific algorithms. Also, some robots wore running shoes or motivational gear (“Bound to Win” headband). Others collapsed at start lines or crashed into railings within meters. All required human support teams for battery swaps (Tiangong needed just three)
Beijing officials framed the competition as akin to “race car engineering” rather than pure athletics, emphasizing the navigation and mechanical innovations required.
“I’m witnessing the evolution of robots and AI,” remarked spectator He Sishu, an artificial intelligence professional.
The marathon exposed key developmental challenges such as battery life remains a constraint despite efficient swaps, smaller robots (under 120cm/3.9ft) struggled with endurance and ocial robots with “feminine features” prioritized aesthetics over athleticism.
As China positions itself as a leader in commercial humanoids, the event—while theatrical—offered comcrete data on how bipedal machines handle prolonged physical stress. With plans to expand testing, Beijing appears to be dedicated to combining spectacle with substance in its robotics push.
