My rover is on wheels and it will fit because it retracts the vacuum in and out, so it will stay 3 feet by 2 feet then it vacuums up the dust. It puts it inside of a jar in the box to protect the jar then it can dig up the soil without getting the dust so it works. It can drive away from or drive up craters so it won't flip over. It is powered by a solar panel from the top and it can retract to get energy for it to move. The rover will scoop about a handful of dirt and a jar will come out of the top and it will dump the soil into the jar and when it's full it will go back to the station and it will drop off the jar and it will go back and repeat.
