My robot's name is S.A.H.T.R it stands for super amazing high tech robot. He can move because he has a track on each wheel. It has a big shovel on the front which digs a pile of dirt. On the back it has a vacuum system that sucks up all of the dirt. It goes through a filter which filters out the lunar dust and the rest of the dirt goes into a box and the lunar dust goes into a different box. That is my robot and how it works.
