Ambitious as it may sound, as per YomiuriOnline, Japan is planning to send a two-legged robot (a biped) to the moon as early as 2015. Japan is widely known for robots of various types and has been tremendously successful in this area, so expecting something like this in the next 5 years may be possible. The project is estimated at $10.5 million (approx).

The hardest part would be to make the robot ‘walk’ on the highly uneven surface of the moon.
