MACs Series of Bots

Our first of three bots is the smallest and weighs the least. It has two claws that close over a chunk of moon dust. It deposits this chunk into a hatch in the back of the rocket. There is a sifter that sifts the dusts in a larger compartment that holds up to 50lbs. The rocks that aren't sifted are transported to the second robot through a tube. The second bot receives and cleans off the rocks to prepare for bot #3 which is a vacuum to suck up all the clean rocks. This process continues until all are done or the capacity is reached. All bots tun on nuclear power. They are made of aerospace grade titanium.
