Star Wars Galaxies had droid which could for example automatically gather stuff for you while you were grinding, so for example you could grind some kind of animal and the droid would ride around and gather a set type of item like "leather" from anything lootable in around. That's how I would see droids or "drones". You build a simple weels + cargo + mechanical hand, add default "gathererer AI" script, set it to "gather bones, alert when full" and boom there you go.
