It seems that ants will naturally gather debris to build a mini stockade around any especially nice food that is too large to cart off in a single piece.
Today’s invention is an enhancement to a robot vacuum cleaner. An ant farm is attached to the cleaner and a nozzle gives the ants access to the carpet.
Periodically, a piece of sugar (red) is dropped onto the carpet or flooring inside the nozzle.
Ants stream onto the floor and extract debris from the carpet surface to build their barricade.
After a while, the vacuum cleaner will move to suck up the ants’ collected dirt -thus enhancing the action of the cleaner.
