Abstract: According to one embodiment, provided is a method for controlling a system comprising a lawn mower robot, the method comprising: a boundary setting driving step wherein the lawn mower robot drives in order to set a boundary of a target work area in which at least three anchors are installed on the boundary thereof; a shadow area determination step wherein, in the boundary setting driving step, the lawn mower robot receives a signal from the anchors and sets, as a shadow area, an area where the signal cuts off; a driving ending step wherein when the lawn mower robot returns to an initial position, the boundary setting driving step is ended, and driving information received from the anchors is stored; an information transmission step for transmitting, to a simulator, the driving information and information on the shadow area and the target work area; an obstacle map generation step for generating, by the simulator, an obstacle map on the basis of the shadow area of each anchor; a screen output step wherein the simulator overlaps an externally provided map and the obstacle map, and outputs same on a screen; and an anchor recommending step for recommending, to a user, positions at which the size of the shadow areas identified within the target work area can be minimized. According to the present embodiment, a user can easily check whether the anchor installation positions are desirable.
