the problem is that in the example the worker only unload one machine at a time and take the part to the drain, but i want the worker to unload multiple machines and take the parts to the drain. For example the worker unload machine A an then go to the Machine B and unload it too, and then take both parts to the drain.
If you use the worker only for transportation, I guess the easiest way is actually to use the Transporter object. I do not have an example available of how to let a worker collect MUs from several stations and transport them to a drop point. Makes sense, though.
