Mitsuo Kawato and other Japanese researchers have proposed a new 30-year, 50 billion yen research program to develop humanoid robots with the "mental, physical and emotional capacity of a 5-year-old human". A Japan Times article compares the projects to the US Apollo Project which sent men to the moon and produced a huge number of technological benefits as a side-effect. (The Apollo project cost the equivalent of 7.2 Trillion yen).
