Why pickup point doesn´t work?
Enclosed in my model the AGV pick up the item on the main road and not at the pickup point - what´s wrong? After the first order, the AGV´s don´t find other items!

I believe that the models are behaving differently not because of the Pickup Point connection but because the Process Flows are different. In the working model you attached, the Process Flow utilizes a Move Object and a Change Visual activity as shown here:
In the model that doesn't work, the Process Flow is missing the Move Object and Change Visual activity.
This is probably where the problem resides. I updated your model to add in those two missing activities and I think it will behave as you want it to now.
Hi @tanner.p
thank you for carification and finding the mistake. This was a hangover form my question:

Benjamin told me to do this. Maybe you remenber, you also answered to these question. Sorry!
I see. I guess the takeaway here is that adding these activities into Process Flow works for some methods of AGV control, while for other methods, the activities need to be taken out. I would recommend just going with whatever works for you. The AGV template is not meant to be fool-proof nor is it meant to work for all applications. You can use it as a starting point and cater it to your needs. Hopefully this helps you build your model. Thanks!
The connections were close, but not quite complete to make this model work. I changed the A-Connect to be from Queue_full_Cont to PickUp1 rather than ControlPoint5 because if the queue is accessible by ControlPoint5, there's no point for the AGV to go out to the PickUp1 control point to load the item.
I also changed the connection between ControlPoint5 and PickUp1 to be a "Look for Work" connection so that the AGV can tell if there's something to pick up when it looks at ControlPoint5.
Hopefully these changes make sense and the model behaves like you want.
Thank you @tanner.p
sure, with your changes the model runs. But I don´t understand why the model don´t work with the pickup point! I build a new simple model (find enclosed) with the same pickup logic and it works! Also in the tutorial it is discribed to model pickup points in this way.
My question is still: Why don´t work my first simple model? Is it a buck or anything else?
