Android robot Honda P-3 walking down stairs in a laboratory. This remote-controlled robot can walk in a line, open a door, turn a corner and climb or descend a flight of stairs. It also has a vision system that allows it to navigate around furniture. The robot is 1.6 metres tall, weighs 130 kilograms and can walk at two kilometres per hour. Its designers hope to eventually produce a robot that can coexist and cooperate with human beings. Photographed at the Honda Research and Development Centre, near Tokyo, Japan.
