%T Control of a servo loop for a vision system %A Tonny Stavenuiter, Herman Roebbers %E Stephen J. Turner %B OUG\-12: Tools and Techniques for Transputer Applications %X Transputers enable the implementation of complex control algorithms for robot systems at high sampling rates. With these new algorithms the need is felt for a better interaction between the robot and its environment Vision is an attractive sensor for the establishment of this interaction. This paper describes the development of a system, in which vision is used to track the tip of a robot link.
