AGV's collecting Boxes and storing them at queue.

Hi,

I have a model, where are two AGV's and they are loading Boxes (the logic depends on the global table 'Orders') and then putting them to queue 'frontRegal', but an error occures, when both of them need to travel to this queue and I want to avoid this collision.

Can anyone help me please?

Thank you.

To solve this problem, I propose one of two solutions:

1. increase the number of possible AGVs on the road between points therefore, collisions may occur

2. add other control points and logic to AGVs

In attached I sent the model

Hi,

thank you, but the problem is a bit more difficult. There is the 'main path' at the 'bottom' of the model and I need to have only one AGV on this path. In your model, that you attached this problem occurs, when both of them are at their 'home' position. Is there another solution? Thank you a lot.

You can change place where AGV should go after unloading the package. Earlier, I typed in to go to the "home" location. So control point is connected by "S" connection. You can send AGv to other place.

you can also indicate destinations by pointing with a pipette.

Can I have another question?

I have attached a model and it makes what I want, but when one of those AGVs does not have any other item to load the another one cannot travel and unload the loaded item at the frontRegal, because the the first one has nothing else to do and stays at the frontRegal. So I need to make any decide block, where I would like to ask if there are any items left, when not, I need to move that AGV to one of the 'paths'.

Do you have any solution?

Thanks for your time.

To send an AGV to a location when there is nothing left to do, you can use the next aquerie and max wait time

I proposes to add another path and control point so that they don't get stuck
