One or more robots are formed to explore the dynamic target object. The target object modeling unit displays a target object area expanded according to the time on a grid map in which is previously built. The route planning unit calculates a predictive route where one or more robot can be moved for the predetermined time on the grid map. The route planning unit plans a route to explore based on the target object area which is displayed in the target object modeling unit and the calculated predictive route. The control unit controls the robot to move according to the route in which the route planning unit plans.
