ASIMO, an acronym for Advanced Step in Innovative Mobility, is a humanoid robot designed and developed by Honda. At 130 cm (4 ft 3 in) tall and 50 kg (110 lb), ASIMO was designed to operate in real-world environments, with the ability to walk or run on two feet. It is the most advanced humanoid robot that can be bought, but it is also the most expensive one, with the price around US $2,500,000. ASIMO can move in crowded places such as shopping malls, station or museums. It has the ability to adapt to the environment, can walk on any terrain and can climb or descend stairs almost as good as a human.
