A laser system for autonomous guidance of robots is presented. This system operates with an environmental model, communicates with the robots and indicates their routes by means of light projection from a laser pointer onto the ground. Image processing and communication with the guidance system allows the robot to detect the laser light beacon on the ground and estimate its relative coordinates. The guidance system subsequently indicates target positions along a desired route. The concept of the system, its kinematic models and operation are considered. The implementation and experimental results are described.
