Solar-Powered Moon Rover To Explore Apollo Landing 151
Mike writes "Carnegie Mellon roboticist Dr. William Whittaker has teamed up with Astrobiotic Technology to develop a solar powered moon rover that will explore the Apollo landing site in 2011. The photovoltaic clad robot features two electric motors in the hub of each wheel, and a half cone of solar generators up top that will power the wheels, run computers, and beam stereo HD video back to earth. The project has been entered in the $25 million Google Lunar X Prize competition."
