Persistence

My robot has many different features including a solar panel, a digger,and treads. The solar panel is for getting power because the robot is in space and batteries would run out of power. The treads are for traveling the lunar surface, I thought they would be better than wheels because wheels come off easier. My robot protects against Lunar dust by being an airtight box with a clear protective covering on the solar panel. My robot is designed to carry a lot of dirt per trip and would most likely be slow moving, but make fewer trips.
