After scaling the cliff walls of the Grand Canyon and driving the Le Mans racetrack for 24 hours, a tiny Japanese robot is set for a new challenge - Hawaii's gruelling Ironman Triathlon course.
The batteries the robot bears on its back, which go on sale in Japan on October 21, can be recharged up to 1,800 times by being placed on a recharger pad.
The triathlon challenge begins on October 24 and will continue non-stop for seven days and nights. The actual Ironman World Championship takes place in early October.
Among its other achievements, Evolta has also walked the 500 km from Tokyo to the old Japanese capital of Kyoto.
