Investigation of Relationship among Robot Motion and Human Psychology Using Emotion and Impression for Human-Robot Collaborative Movements

Abstract

In this study, we investigate relationship between robot motion and human psychology in collaborative movement situations. To realize collaborative movement, the robot needs to consider psychological aspect. This makes robot to estimate human intention and psychological states, and convey robot's intention to human. For evaluating human's psychology directly, we use 9 kinds with 3 strength emotion items. We apply semantic differential method and use 14 adjective pairs of impressions. The subjects are asked to answer questionnaires in 20 scenarios where the robot passes through the corridor including two humans. The result of experiments using an actual mobile robot with one arm indicated that motion and psychology related such as that robot's touching motion for letting human make way evoke surprise and humanlike.
