Quite a robot! You guys are ahead of the curve. I expect stacking on stacks will become more and more commonplace as designs begin to converge on the singular meta.
Stacking on stacks allows for versatility, especially in quals when you haven’t a clue who you’ll be with or against ahead of time.
At some point, we’ll see the point of diminishing returns between tray size and intake speed. If we still want larger stacks at that point, we’ll need to stack on stacks. Additionally, having the capability to do so means that you can very quickly intake about 7 cubes, rather than having to slowly intake 14.
However, a point against stacking on stacks, which its opponents have adamently pointed out, is that there are only 66 cubes on the field. Ideally, you want to stack most of them for yourself, but your opponents will get quite a few for themselves. An average 6 stacks of ten is 60 cubes, leaving 6 for tower play.
So that could be a point against stacking on stacks and the extra motors required to do so.
Despite this, however, I do think that stacking on stacks and the versatility it allows is worth the aforementioned drawbacks thereof.
