Recently, the need of robot partners is increasing. Such robots should have an emotional model in order to co-exist and to realize the natural communication with people. In the communication, nonverbal communication and emotional expression based on emotional model are very important for robot partners. Moreover, facial and gestural expression should be adaptive to a user of the robot. Therefore, we propose a design support system of arm gestural and facial expression of robot partners based on interactive evolutionary computation and Laban features. Next, we conduct several experiments of the proposed method, and discuss the effectiveness of the proposed method.
