Rover digger

All orange parts move. The round black pieces are motors. The light grey part, which is attached to the orange part in the back form a hinge. The grey part is attached to the Rover while the orange part is attached to the digger. All red parts are stationary.The two orange cylinders which are attached to the motors in the back (which is attached to the rover) move the digger up and down. When the shovels rotate to inside the digger, there is a short drop which allows the dirt to fall out of the shovel into the small cavity which is then pulled into the storage container by the auger. The two shovels rotate in opposite directions.To drop its payload the bottom storage doors open.If the shovels are removed the digger forms a scooper.
