My robot's name is Subsurface. He is 30 in. by 20 in. by 20 in. It has treads covered in titanium and steel. It is controlled by an astronaut so it can avoid craters and big rocks. It has compartment scooper arms that are made from titanium and steel, and it holds the dirt in the arms and then releases the arms so they can dump the dirt. Its energy source is solar panels. It has a vacuuming system to clean the inside and outside.
