'''Laser guidance''' directs a robotics system to a target position by means of a [[laser]] beam. The laser guidance of a [[robot]] is accomplished by projecting a laser light, image processing and communication to improve the accuracy of guidance. The key idea is to show goal positions to the robot by laser light projection instead of communicating them numerically. This intuitive interface simplifies directing the robot while the visual [[feedback]] improves the positioning accuracy and allows for implicit localization. The guidance system may serve also as a mediator for cooperative multiple robots.<ref name=Paromtchik2006>
