At 4 ft. 3 in. (1.3 m) and weighing 115 lb. (52 kg), ASIMO could be a young child. But as far as robots go, ASIMO is all grown up. Honda Motor Co.'s ASIMO is possibly the world's most advanced humanoid robot. ASIMO — operated by its human master either from a workstation or by remote control — was first unveiled in 2000, the latest in a collection of humanoid prototypes that Honda has been developing since the 1950s. There are over 100 ASIMO units in existence today, selling at just under $1 million apiece.
