Abstract: Multi mobile robots objects collection task is a complex distributed dynamic system, the spatial distribution of sensors and actuators, the complex interaction between robots and environment and among robots themselves make it difficult to be controlled by centralized control mode. This paper analyzes the characteristics of multirobots objects collection task and points out that it especially fits the method of multiagent. Under the guidance of multiagent method, this paper discussed the system architecture and each agent of the system, at last, the system is implemented successfully.
