NASA Digging Robot

My digging robot collects regolith so that astronauts can build their base with it. Some features it has include a camera, backup solar panels in case the battery runs low, a claw to collect regolith with, and 5 inch steel wheels. I will keep moon dust off and out of my machines by having 2 layers of steel on the outside, and so there are no gaps the steel would be bent into shape in extreme temperatures. The scale of my machine drawing is two inches equals one foot. PS. NASA rocks!
