Abstract
This paper addresses a new cooperative theory of multiple robots which adapts them to environmental changes. In practical applications with multiple robots, the environmental elements, which are target object condition, number of working robots, and so on, can change easily through their interactions. The new cooperative theory adapting environmental changes is needed. The proposed cooperative theory is inspired by social cooperative characteristics of human-beings, especially subjective evaluation and imitation. This work is experimented by Sheep-Dogs Simulation (SDS) to validity of the theory. The SDS consists of multiple sheep-dogs, named dog-agents, and multiple sheep-agents. In conclusion effectiveness of the theory was proposed in SDS. Multiple robots would be adapted to environmental changes by the theory.
