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.
