Front and back road wheels are generators while the middle two are motors. Fan to blow lunar regolith forward. Vacuum attached to the wire above the drill to suck up soil then shoot it out to the side. Rechargeable battery pack for energy from generator to go to, then other power supplies take from the pack. Cover is not glass. Camera on the end of the drill. Battery/ batteries need to be able to be charged easy and take a long time to run down.
