Multi-robot team work with benevolent characters: The roles of emotions

Multi-robot team work is necessary for complex tasks which cannot be performed by a single robot. To get the required performance and reliability, it is necessary to develop a proper cooperative task. The robots need to be intelligent enough to adjust with dynamic workload and environment. Benefits can be amplified from a team if benevolence combines with cooperation. The benevolence behaviors among the team members are extra benefits to the society. There is a flexible relation among intelligence, benevolence and emotions. We describe an emotion model to be used for each of the members of a multi-robot team. In respect of some drawbacks with the existing approaches, we present an emotion based multi-robot cooperation with some benevolent characters.
