単純な協調メカニズムを有する群ロボットの適応的な分散物収集

Foraging behavior to collect objects distributed in the field is one important task suitable for multirobot system. For effective performance, proper cooperation should be introduced into the robots. In this study, we propose a novel method for cooperative collective behavior of swarm robots. Once the robot finds an object, it stops there and broadcasts its position to other robots. The robots which receive the signal try to move towards the signal source and to search for another object. In our proposal, we introduce a “doubt point”, which is incremented when the robot fails to find another object. If the point exceeds given limitation, the robot ignores the signal even if it detects the signal from other robots. In this paper, we confirm the effectiveness of this algorithm in several different types of object distribution by computer simulation.
