Emergent behavior in social insects has inspired a new class of robots called swarm robots. However, computational and economic constraints regarding inter-robot communication still persist. This paper introduces a low cost architecture facilitating co-operative searching and transport through a master-slave swarm robot concept. Especially, we focus on the directional movement of the slave robots depending on the position of the master robot without using a camera. Experimental results show that the architecture is an economic solution for macro level inter-robot communication involving positional data on an even terrain.
