Based on the background of the distributed swarm robotic foraging mission

a control method of distributed swarm robots is explored.The swarm robots are behaviour-based and have simple acting.They form chains through corporation by using themselves as beacons.The swarm robots form a chain path between nest and food.By the simulation

it is concluded that if the number of swarm robots is enough

it is appropriate to have three or four robot chains of each root.It is much more efficient to search multi-food than single food and to have a longer step size.
