Abstract
This paper is to propose a method to control a mechanical system to move along laser beam, which may be useful for the teaching of the movement to robots. The mathematical model of the controlled system is constructed so that one of the coordinate corresponds to the laser beam, and the control problem is divided into the control along the beam and that of the deviation from the beam. Two controllers to track ramp are designed and practically realized by a minicomputer for these controls. They work satisfactorily when they are used for the control of three-dimensional linear motion mechanical system.
The sensor to measure the direction of and the deviation from the laser beam is also experimentally constructed and used for the experiment.
