AGV Drive In Rack

Continuing my experimentation with the capabilities of AGV network, in the attached model, I want to make the AGV travel inside a Drive In Rack (Rack1 in this model) and drop the flow items it is carrying at each bay. I created control points below each bay and designated them as drop off points. It seems that the AGV always drops off the items at the control point connected to the rack with location connection and then the items move in to the corresponding assigned slot.

Model 1:

AGV_Drive_In_Rack.fsm


In a separate model, I split the rack into 4 independent racks, each with 1 bay. Each rack is connected to a control point with location connection. These control points are connected to a main CP as drop off points. In this case, the AGV drives to the CP and performs the expected operation.

Model 2:

Separate_Rack_With_AGV_DropOff_autosave.fsm


What do I change in model 1, so that the AGV drives in the rack, to the assigned bay and drops off the flow item it is carrying? I am searching for a robust solution which would let me scale this approach to multiple racks, and avoid creating hundreds of bays with the approach implemented in Model 2.

Any pointers?

I think I found an approach. I insert 2 additional tasks to let travel the taskexecuter to a location in the model. Then the item is unloaded to the rack to an already assigned slot and then I let him travel back to the control point where the travel on the agv path system had finished.

  1. Assign slot On Creation or before Offset Travel starts
  2. Let the taskexecuter travel near the location of the slot, perhaps you have to design the path over a route of locations (Taskexecuter On Receive Tasksequence)
  3. Let him travel back to Control Point where the AGV travel had finished (Taskexecuter On AGV Deallocate)
