How to let AGV turn back to its original path?

Hello, I wonder is there any way to let AGV travel back to its path? In the attach model, i want CAR2 to travel back instead of going forward. Is there any to avoid this problem? By the way I didn't use process flow, only use 3D, so hopefully can solve by 3D.

Thank you for your help!!!

The reason why car2 is leaving its normal path is because it is actually taking the shortest route to its next destination:

After delivering an item to Queue32 (circled in green), its next task is to travel to Queue7 (circled in light blue). Believe it or not, but the blue path to Queue7 is actually shorter than the red path, so car2 takes that route when traveling from Queue32 to Queue7.

The way you fix this depends on how much you can / are willing to change your model. If you can shorten the red path from Queue32 to Queue7 or make the blue path longer, your model will work as you want it to. Here's a model in which I added a shortcut to make car2 take the red path: shuttleversionupdated.fsm

You could also change the locations of the queues or which AGVs travel to which queues. If you can't use any of those solutions, you will likely have to use Process Flow to customize car2's logic so that it stays where you want it to.

I hope this helps! Let me know if you have any questions on this.

Thanks a lot, because of the constraint,the shortcut is unavailable, but i already shorten the route of Red path.

It seems like using process flow to control the logic will be more easy, thank you for the advice.
