A* Navigation Problem with Barriers

[dipto6D54P]

Hi,

I am trying to play out some ideas in FlexSim to stress test route searching algorithm / A* navigation.

I have intentionally created a unresolvable path problem. Ideally the AGV shouldn't be able to reach the location. But, at one point it stops respecting the barrier and gets the object.

Actually, I want it to come back to the starting position if it can't resolve the path. How would I do it? Can I do it?

I am attaching my model.

Hello @dipto6D54P,
A* will have the task executer travel to the closest node to the destination object. You can see this in our manual, Working With A* Navigation,  under the adding bridges subheading. 

You can also find in our manual other information and troubleshooting techniques. Our manual also states "A* is an open-source algorithm that was developed by a third party outside of FlexSim. For that reason, there are more in-depth guides you can find about how the A* algorithm works if you need one. Just do a simple internet search and you should be able to find plenty of information."
