Cooperative seamless communication with collective intelligent robots

Abstract

In collective intelligent robots, communication capability is considered as a key feature to decide how to design the collaboration policy. A cooperative routing robot system is suggested to maintain the communication capability in between robots and an algorithm to establish a seamless global communication is proposed. The proposed algorithm is composed of two steps. At the first step, the communication links are monitored and the disconnection of network is predicted by analyzing RSSI (Received Signal Strength Indicator) and LQI (Link Quality Indicator) among cooperative robots. Then, the robots are driven forward inside a safety region of communication using virtual force model on the basis of the strength of the networking signal. Experiments with routing robots and sensing system verify our proposed system and algorithm are valid in real environment.
