Is it possible to have AGVs ignore "collisions"?

I am working on a model dealing with shuttle routes. Preferably, I'd like to just have a single 2-way agv network path that will allow agvs to pass by each other going opposite directions. I suppose I could just create a second network parallel to my first traveling the opposite direction, representing the other side of the road, but that could get cumbersome. Any ideas?

You can have AGVs go down a two-way path and ignore collisions with each other.

Just set the path to No Accumulation, and adjust the control point allocations such that multiple AGVs can be traveling down the path.

Here's an example model showing this: agv-ignore-collisions.fsm

Exactly what I was looking for! Thanks! The Max Accumulation value also was a big factor that I was missing.

Hi @Aaron C,

I think that making two parallel travel networks is going to be your best bet. There may be a way to customize the collision behavior, but such a solution would be very complex.

Have you considered using Network Nodes instead of the AGV path? I personally find the Network Nodes easier than the AGV path. You can add all network nodes, then set the network to be one-way and no-passing. As you connect the Network Nodes together using A-connections, it will automatically be configured for one-way and no-passing.

I have attached a simple sample model where I implemented this. Also, check out the link to the Network Node documentation.
