Abstract
Home service robots must have implements like conversation interfaces so it can be easily accepted by the users. To get basic data to develop such a robot, we investigated the robot's impressions of when it responded to the instructions of operating a TV or when it planning the cooking recipes. Thirty men and thirty women of different age groups rated the impression on using the robot. The results indicated that we should find a better way to inform to the user when a word was not in the robot's database. Moreover, we should reconsider what kind of the robot's gesture the users need. In addition, the embodiment of the robot made the impressions better. In addition, women judged the robot positively probably because the robot had a cute appearance.
