Research On Task Allocation Algorithm Of Emotional Robot Based On Personality

Emotional robot is the robot added with emotion factor by artificial emotion and artificial intelligence. They can be more intelligent than rational robots,and can adjust their behaviors through emotional mechanism. The emotional factors and personality factors have improved the diversity and autonomy of the robot.The task allocation of emotional robot is to research how to select the suitable robots to participate in the task.Usually,the allocation algorithm will consider the emotional mechanism,to minimize the time cost and maximize the reword.This problem has become the hot issues in multi-robot areas,to solve this issue can improve the stability of multi-robot system,and make full use of the multi-robot systems.The main contents included as follows:Firstly,Based on the multi-robot pursue platform we research task allocation of emotional robot, we establish a emotional model, in it we use the basic emotions to show emotions,and build an Emotion Contagion Model to describe the interaction between emotions.Secondly,This paper proposes an emotional robot task allocation algorithm based on emotional contagion. The emotion state and the willing for cooperation is different.Through emotion contagion some of the negative emotion state robot can turn into positive. So,we have more flexibility to select the task leader and the cooperator robots. Combining with task allocation algorithm,we can complete the team leader and collaborators recruitment. Experimental results show that the proposed algorithm can reduce the total pursuit time and improve the team total reward.Finally, we optimized the task allocation algorithm previously proposed,the introduction of OCEAN personality model of psychology to study the effect of emotion robot character, and built the map between behaviors and personality.we proposed an task allocation algorithm,in the selection of team leader stage,we chose the one who have the higher value of leadership,and in the selection of collaborators,we chose the one who have the higher value of group preference,combined with the emotion contagion,we can select a more efficiency task team. The simulation results verify the effectiveness of the personality model, and concluded the task allocation algorithm is more effective.
