Small scooper but Big drill

My robot is a tank-like robot. It has tread wheels, also a camera and a scooper that is small. It also has a drill to get stuff loose.It has a solar panel and that's when it gets the energy it needs. But the most important part about it is the storage. The way it is going to work by getting the rocks is the drill will break them up. Then the scooper will pick it up and put it in the storage and the way my robot will get dust is from the scooper because it has a little vacuum on it so it will suck it all up. It will get back to the base because someone is going to be controlling it and after they get everything then they can return to the base for research.
