Apparatus for controlling mobile robot

In an apparatus for controlling a mobile robot having movement mechanisms and work mechanisms both connected to a body, actuators for driving them, and a controller for controlling an action of the movement mechanisms and the work mechanisms through the actuators, the controller comprises a person detector to detect a person located in a vicinity of the robot, a position determiner to determine whether the position of the detected person is within a first range or a second range, and a regulator to regulate the actions of the movement mechanisms and the work mechanisms when the position of the detected person is determined to be within the first range or the second range.
