Slot as a destination in unload activity

I hope fork could transport to the bay it's going to unload, so I use a Table for referencing bayID and ControlPoint.

I'm having problem in the unload activity, I write token.slot as forklift destination, this cannot find a location because the controlpoint it found isn't the slot. But if the destination is Rack04 directly, I cannot achieve animation that I want. What could I do to solve the problem if I need to use AGVNetwork. Thank you!

Since you placed a travel activity in front of the unload, the forklift should travel to the corresponding slot and unload into the rack from there as all points are connected to the rack. Could you elaborate what the animation that you want to achieve is?

Hi, @Felix Möhlmann I hope the forklift could face the rack, and also drive to the bay that the slot it found.

So I have same amount of cps as bays, hope could let forklift face the slot, instead of stopping in front of the rack and without load/unload action.

The AGV network does not support offset travel like the travel network does (First travelling to the connected node, then to the actual coordinates). As such the fork of the transport also doesn't move when loading/unloading.

Your solution is is probably close to what can be achieved. If the position the extra control points is close enough, you can simplify it a little. Set the "On AGV Offset Travel" trigger in the AGV network properties like in the screenshot. That way, the closest control is chosen automatically in the offset travel of the "Unload" activity.

If you assign the control beforehand like currently you could adjust the position further with kinematics after arriving at the control point via the "Travel" activity (resuming travel on the network will teleport the TE back to the control point). The fork could be moved up like I already described here:
