A method of inspecting plants for contamination includes generating a first series of images of a plant using a camera mounted to a frame being moved along a planting bed by a harvester, identifying a region of interest displayed in the first series of images as a region of contamination on the plant based on a color criterion and a morphological criterion applied to the region of interest, and transmitting data including an instruction to increase a vertical distance between the plant and a cutter of the harvester to avoid harvesting the plant in response to identifying the region of interest as the region of contamination. The method further includes generating a second series of images of an additional plant as the frame continues to be moved along the planting bed by the harvester while the vertical distance between the plant and the cutter is being increased.

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.
