Recently, many types of robots have been developed for not only industrial manufacturing but also interacting with human. Robots designed for human-robot interaction are expected to have the ability of communicating with human smoothly. In this paper, we propose the character giving model for
robot. This model makes robots individual-beings that are varied with each user. We aim to develop more humanly and empathetic robots by using this model. Robots dynamically get their own characters based on the tendency of user’s behaviors which are classified into two dimensions: dominance-submission and acceptance-rejection. Through the interaction experiments between human and the robot with the proposed model, we confirmed that proposed model could give various characters to the robot, and the character, which was given through the communication with a user, suited for each of the users.
