Moon dozer 6000

My robot will move the lunar regolith by using a backhoe to scoop it into a big cart. The cart will be attached to the back of it and will use spiked tires to follow the robot. The amount of lunar regolith it can carry back and forth will vary depending on the amount you want to carry. My robot will have a substance that the lunar regolith does not stick too. My treads will be spiked so that it can move easier. I will have to find a substance that will stay on the robot and not freeze because of the temperature and also work for the intended purpose. At first I was thinking about a type of oil or liquid but that will probably freeze or just slide right off the robot, but thinking made me get plastic.
