It's not Diversified's fault at all that this board is unreliable. It's the technology being used that's unreliable.
Using IR is very similar to the old "Wireless" telegraph from long ago. There are no channels... anybody starts keying their telegraph (pushing buttons on their remote) and everybody hears it.
IR wasn't really meant to have multiple unique signals going to multiple robots at the same time. Also, remember most television remotes are made to work in a living room, and I doubt many living rooms are as big as a FIRST field (or as brightly lit).
So, not at all because of Diversified but only for the sake of physics, we aren't using an external IR input during autonomous this year.
But I think our robot does pretty well without it...
Thanks Diversified for making a great donation of Time and Money!
