Ok, thanks for clarification. I am asking because Aria provides the 
summed-up positionExtern but the MarsActuator provides the values in the 
-PI...PI range. I would like to use the Skid4Odometry for both.

Is there a rock standard in which range the values should be and 
therefore how to interpret these values?
