Disclosed herein is a self-propelled traveling apparatus capable of precisely determining whether a human is sleeping or awake, thereby eliminating useless alarms. When a human is detected by one of four pyroelectric sensors, the body of the self-propelled traveling apparatus is turned so that a CCD camera faces the direction of a pyroelectric sensor that detected the human, and takes images of the human. Then, based on the imaging signal generated by the CCD camera, the movement and posture of the human is detected. When it is determined that the human is at rest and lying down, the human is considered sleeping and an alarm is sounded at a preset time.
