A robot includes a robot sensor for sensing abnormality around the robot, a moving portion for moving the robot main body, and a movement control unit for controlling the moving portion so that the robot main body is moved to a destination determined according to the information sensed by a fixed-position sensor fixed to a predetermined position outside the robot. The moving destination may be determined by the total control unit of the robot main body according to the information from the fixed-position sensors or by a center communicating with the robot according to the information from the fixed-position sensors. Since abnormality is sensed by the fixed-position sensors together with the robot sensor, the fixed-position sensors may have low accuracy obtained at a low cost. That is, by reducing the cost required for collecting external information, such as by the fixed-position sensor, it is possible to provide a monitoring system capable of collecting ambient information (such as abnormality information) without lowering the accuracy.
