ASIMO, an acronym for Advanced Step in Innovative Mobility,[1] is a humanoid robot designed and developed by Honda. Introduced on 21 October 2000, ASIMO was designed to be a multi-functional mobile assistant.[2] With aspirations of helping those who lack full mobility, ASIMO is frequently used in demonstrations across the world to encourage the study of science and mathematics.[3] At 130 cm (4 ft 3 in) tall and 48 kg (106 lb), ASIMO was designed to operate in real-world environments, with the ability to walk or run on two feet at speeds of up to 6 kilometres per hour (3.7 mph).[2] In the USA, ASIMO is part of the Innoventions attraction at Disneyland and has been featured in a 15-minute show called "Say 'Hello' to Honda's ASIMO" since June 2005.
