Recently, more educational-support robots, which support learning, are paid attention to. However, the problem of these robots is that a user loses his/her interest in them. To solve this problem, the previous study proposed a sympathy expression method for educational-support robots to enable them to express sympathetic emotions when interacting with learners. The previous study suggested the robots which uses the sympathy expression method prompt learners to reduce losing his/her interest with robots in collaborative learning. Although the sympathy expression method expresses the emotions by changing robot’s facial expression, the existing study of Human-Robot-Interaction suggested robot’s body movement was effective for interaction with humans. We think that the sympathy expression method that expresses the emotions by robot’s body movement and it’s facial expression can give more good impression to learners than the sympathy expression method that expresses the emotions by only robot’s facial expression. Thus, this paper investigates the impression effect of the robot using the sympathy expression method that expresses the emotions by robot’s body movement and it’s facial expression.
