Paper Abstract

In optical sensor systems for guiding a welding robot along a seam a "look-ahead" or "preview" distance is necessary. The look-ahead-time is used to advantage in control algorithms which can compensate for delay times in the robot controller. Simple and sophisticated control methods are described. With the so-called delayed shift method, originally intended for globally straight sections, it appears to be possible to track more complicated trajectories, without the requirement of a two-way interface between sensor and robot.
