Robot base movement

Dear Friends,
In the following attached model i wonder how the Robot moves from one point to another without using any network node. somebody throw some light on this.
(Flexsim 6 model)
Regards,
Manoj.

you have built a network for the robot befor and deleted it. Flexsim builds a coupling between the navigator and the robot and assumes that a taskexecuter has to travel in the model. Without the network flexsim works with the standard behaviour now. If you delete the coupling node under the navigator node the normal robot behaviour is working again.
