A technology company in Japan is organising the world's first marathon for robots.
So far, five robots have been entered for the event, which is expected to last four days and test the machines' durability and manoeuvrability.
The "Robo Mara Full" starts on 24 February and is open only to androids with two legs. The robots must complete 422 laps of a 100m indoor track to cover 42km (26 miles). The race is nonstop – except for battery changes and repairs – and survivors are expected to cross the finish line on 27 February.Reuse content
