Abstract
This paper addresses impression evaluation of the communication robot from an aspect of approaching motion. From technical progress in recent years, we can expect that a robot will play an active part in our life. Coexistence of people and robots needs communication such as movement, a sound, gesture, and so on. For this reason, we build a communication robot system which play rock-paper-scissors including approaching motion. From the result of this game, we conducted the investigation and analysis of the impression which people receive from a robot.
