public class RelativeWheel
extends MotorController
implements Positioning

Extension of the MotorController class. Its aim is to provide a simple interface for the STELLA WIFSIP wheel operation. The two important method can set the wheel in its zero position and (then) in arbitrary position specified by the holes in the wheel. The class has syslog capabilities through the protomatter syslog classes. last modified: JB, 25.04.2007.
