ABSTRACT

Foraging is a powerful benchmark problem in collective robotics

for several reasons. Firstly, sophisticated foraging observed in

social insects, recently becoming well understood, provides both

inspiration and system-level models for artificial systems. Secondly,

collective foraging is a complex task involving the coordination of

several-each also difficult-tasks, including efficient exploration

(searching) for objects, food, or prey; physical collection (harvest-

ing) of objects almost certainly requiring physical manipulation;

homing or navigation whilst transporting those objects to collection

point(s); and deposition of the objects before returning to foraging.

And thirdly, effective multirobot foraging requires cooperation

between individuals involving either communication to signal to

others where objects may be found (e.g., pheromone trails or

direction giving) and/or cooperative transport of objects too large

for a single individual to transport.
