Use A* to prevent AGV collision

AGV collision.fsm

How should I modify the model to prevent AMR collision

I have already unchecked "Ignore Inactive Members",but the blue circle still overlap.

The size of the object (and thus circle) has no bearing on the A* collision avoidance. As long as the task executers are occupying different A* grid cells, they don't count as colliding.

Taking size into account is something the developers might consider in the future (https://answers.flexsim.com/questions/115564/occupy-nodes-in-the-a-module-according-to-the-size.html), but currently this is sadly not possible (or only through workarounds via preferred/forced paths, barriers and dividers).
