My robot will dig/scoop by using a drill that has a vacuum cleaner inside that will suck up all dust around the drill. The vacuum and drill will be powered by solar power and small batteries. My bot will carry lots of dirt and distribute smaller robots to go pick up more batteries if the big robot can not rtb (return to base).then they will drive into the mother robot and power it. It will use static proof surfaces and one big surface that the dust can stick to and then it will dump the dust into the whole.
