The hue algorithm they brag about is intended to remove the intensity variations. My expectation is that if you train it with an LED ring light, it will have a very strong affinity to your LED color. This should play well with the retro-reflective tape FRC uses and should eliminate effects of ambient lights. You may want to pick a unique LED color for your ring light so you don't lock onto another robot thinking it is a target - unless that is what you want?
Obviously no one has tried this on an FRC field yet. Given it is available to everyone, I cant see any reason it would not be legal. If they run out (which they have not yet), it is no different than the year that FRC consumed the world supply of fisher price motors and many teams were left wanting. We ordered two for $115 and will post how they work out when we get them. Not much of a risk and potentially a big advancement if they live up to expectations.
