My machine is made almost entirely of aluminum, because regolith is magnetic and I want my rover to be able to move it around for the fastest moving possible. There are three scoops, the two on the sides are made of nickel, so it will stick to the scoop a little bit for research purposes. The big scoop in the center allows the wheels to function without getting stuck with the regolith. Wall-ee is entirely solar powered with four solar panels on the top of the rover and the black squiggle on the front is a camera. The green represents a cleaner, greener future with new colonies on new planets.
