Chinese Humanoid Robot Walks 66 Miles Thanks to Hot-Swappable Batteries

The Chinese AgiBot A2 is now the Guinness World Record holder for "longest journey walked by a humanoid robot" after spending three days travelling over 66 miles, TechSpot reports. The bot did use hot-swappable batteries, which allowed it to keep going even when switching over (and we don't know how many times that happened). Still, it demonstrates that the continued, long-term operation of these kinds of robots is already possible today, over extended distances and across a variety of surfaces.

Walking a long distance is still a major achievement for humanoid robots, which tend to fall over (especially if they're Russian). But doing so over a multi-day, 66-mile trip across asphalt, tiled pavement, bridges, slopes, and hills is a new milestone entirely.

The AgiBot A2 began its record-breaking journey at Jinji Lake in China's Jiangsu province on Nov. 10 and ended up at Shanghai's Bund waterfront ...
