Chapter 5: Commissioning
5.4.2 Configuration –> Guidance
5.4.3 Configuration –> Wheels
The configuration of the wheels specifies the characteristics of the vehicle. In the case of
this vehicle example, the navigation controller must know that there is an unsteered fixed
castor and where it is located. With this information, the navigation controller selects the
controller for non-omnidirectional vehicles and specifies the symmetry axis (the straight line
on which the instantaneous centre of rotation moves during steering).

The other fixed castor of the vehicle contains no other information and can therefore be ig-
nored. If this were a driven wheel, it would also have to be parameterised, as the navigation
controller would otherwise not calculate any target values for the speed.
The co-ordinate system must always be selected in such a way that the vehicle x-axis points
forwards. The steering angle of the wheels and the vehicle orientation are 0 in this direction.
If a steering angle or the vehicle turns to the left, the angle becomes more positive. The ve-
hicle alignment moves between 0° and 360°. The steering angles move between -180° and
+180°. If the vehicle moves in a forward direction, a wheel with the steering angle 0° must
indicate a positive speed.

CAN ID Segment Rx
772d = 304h CAN identifier under which the target segment list is
received (freely definable, is entered in decimal form)
CAN ID Segment Tx
773d = 305h CAN identifier under which the actual segment list is sent
(freely definable, is entered in decimal form)
CAN ID Segment Search Tx 774d = 306h CAN identifier under which the results of the segment
search are sent
CAN ID Control
775d = 307h CAN identifier under which the vehicle control system
sends the specifications to the navigation controller (freely
definable, is entered in decimal form)
CAN ID Status
769d = 301h CAN identifier under which the navigation controller sends
the actual status to the vehicle control system (freely defin-
able, is entered in decimal form)
CAN ID Error message
768d = 300h CAN identifier under which the navigation controller sends
the error messages to the vehicle control system (freely
definable, is entered in decimal form)
