Recently various robots spread in the home, and, in the future, familiar partner robots seem to appear in human life. Therefore, it is necessary that robots learn desirable behavior in order to establish a life of the cooperation between robots and human. We had proposed the methods using interactive GAs so that robots acquire the behavior that the human likes. In addition, we applied this method to the pet robot AIBO. In this paper, we try method, which the robot acquire the behavior, with human interaction using the touch sensor.
