A knee-high humanoid has narrowly won the world's first full-length marathon for two-legged robots.
Robovie-PC crossed the finish line in the Japanese city of Osaka just a second before its closest rival after more than two days of racing.
The 26-mile (42km) race involved 423 laps of an indoor track at an average speed of 0.77 km/h.
Two other androids are yet to complete the course, while one pulled out after just one lap.
