B.E.R.D.

The Best Engineered Robot Digger (B.E.R.D) is an excavators type robot that injects the tube into the soil and sucks out dirt. The robot meets the requirements and is about 3 ft x 2 ft x 2 ft in size. The robot will be electrically charged by a power station in the moon base. The robot works off of a battery that when it finds fertile soil will inject a needle into the ground and suck up dirt until it's full. It then goes back to the station and dumps it. The robot is made of a metal alloy so it sticks to the ground. The robot also has a waypoint marker so when it runs out of electricity, it will be found. The wheels are all-terrain wheels.
