#4: Gold Diggers

This is desert idea, I get that a lot. 

Imagine many roaming robots, solar powered. They would shovel the sand or a small area in the desert. Their purpose is to check if the area under the sand, now visible, has gold veins.

They would inspect the area and if that is not found, keep shoving sand, moving the hole from place to place
