Abstract
In order to coordinate the movements of two movable parts on a spinning frame and a service robot, a system is provided in which one part carries two sensors which are used to detect the position of the other part within the respective measuring ranges of the sensors. This system provides for rough positioning of one part to the other at a relatively high speed until the first sensor detects the second part. Thereafter, coordination of the movements of the two parts takes place within narrow tolerance limits using the second sensor which has a narrow measuring range.
