BEIJING, CHINA - APRIL 19: A humanoid robot is followed by its team in a golf cart carrying a back-up robot as it runs at the start of the Beijing Humanoid Half Marathon on April 19, 2026 in Beijing, China. More than 100 humanoid robots from 76 institutions across China lined up alongside 12,000 human runners Sunday in Beijing's E-Town district for the world's largest humanoid robot half-marathon, following the same 21-kilometre course on separate lanes in a 'human-robot co-running' format that for the first time included teams competing under fully autonomous navigation.
