Abstract
Embodiments include an apparatus and methods for removing unwanted plants or weeds from an area such as an agricultural plot or lawn. The apparatus includes a three-dimensional imager configured to capture plant images and locate plants; an image processor configured to distinguish between wanted and unwanted plants based upon the captured plant images; at least one laser device configured to emit a laser beam having power sufficient to damage the unwanted plants; a laser beam controller configured to direct at least one laser beam toward the unwanted plant; and a chassis configured to support the three-dimensional imager, the laser device, and the laser beam controller. The chassis is configured to be moved across the area.
