To provide a mobile robot system that requires no advanced computing processor without an operator continuously observing a screen.

A touch panel 22 is configured so that an arbitrary position in a displayed screen can be pressed by an operator for specifying it. An integrated operation interface (the touch panel 22 and a manual operation part 23) is provided for controlling a moving mechanism for a robot to automatically move the robot and for controlling the moving mechanism in response to the manual operation of the operator, using an actual position corresponding to the position of the arbitrary point as a target position (a target point P) when the operator specifies the position of the arbitrary point in the screen displayed on the touch panel 22 (touches the screen).
