Looking at this from an eliminations standpoint, only two robots should need the feeder station at any given time with maybe one overlap. If you have one robot stacking stacks of three or four on the ramp, one robot collecting recycle containers and placing them on the three high stacks, and one robot stacking a three high with a container onto another three high. Your quickest stacker does the stacks of three, your best manipulator does the final stacking, and the last robot does as many containers as you can. Three unique roles. Although they are lifting just the same for the totes, it is different enough to that at any median level regional atleast two of the roles wouldn't be interchangable, of course this would change at champs, but for the most part there are three independent roles, and that's with ignoring the noodles.
