Abstract
A method comprises: a lawn mower robot driving to set a boundary of a target work area in which at least three anchors are installed on the boundary; the lawn mower robot receiving a signal from the anchors and setting, as a shadow area, an area where the signal cuts off; the lawn mower robot returning to an initial position and storing driving information received from the anchors transmitting, to a simulator, the driving information and information on the shadow area and the target work area; generating, by the simulator, an obstacle map based on the shadow area of each anchor; the simulator overlapping an externally provided map and the obstacle map, and outputting the same on a screen; and recommending, to a user, positions at which the size of the shadow areas identified within the target work area can be minimized.
