Dust-Eliminator

My robot is called the DUST–ELIMINATOR. There is a drill at the bottom that drills through rocks. Also a tube at the bottom that sucks up the soil and puts the soil into a chamber. The chamber has two more tubes inside of the chamber. When the robot stops and the robot does not drill that's when the antenna at the top goes off. This causes the back door to open, which will turn on the conveyor belt. The conveyor belt will empty the soil when it is instructed to do so. The robot is solar powered.
