A robot of the present invention moves to a place where a user is, in response to the voice of the user who is calling the robot. Then, when the user presses a switch, the robot recognizes that the user desires to send an urgent call and dials a pre-registered telephone number for sending urgent calls. When a receiver responds, the robot reads out and delivers a predetermined message to the receiver as a voice message, and switches the telephone to the handfree state so that the user can talk without holding the telephone.
