Master Shifter

The robot created is designed to move moon dust from one side of the moon to the other. The contraction shovel picks up the sand and puts it inside of itself to reduce the amount of space the robot takes. It stores the sand and travels to the given destination on the geared wheels for better grip to the surface. When it gets there it releases the sand from underneath it. It is like a shutter contraption, and it works with the force of gravity. The robot needs to be charged every 20 rounds for 30 minutes.
