Bingo. Look for all of the known field entities that can be used to localize the robot on the field, especially those that may get you to a position where your robot has a high chance of scoring, and then look for the simplest way to identify those and incorporate them into your targeting system.

As an example, exercise, my HS basketball coach told players to focus on either the front or rear of the rim, depending on how their shooting motion tended to loft the ball. Then he admitted that he still focussed on the net, and that when he was a youngster he started at a solar eclipse long enough to scar his retina. Since he couldn't actually make out the rim reliably, he looked at the net. I'm sure other players look at some portion of the backboard rectangle.

The field has nice lines on the floor to follow to a known location. It has a fender to align against or locate with a sensor. And it is worth mentioning that the walls of the field are nice for alignment.

The retro-reflective tape was definitely put on the backboard as a possible vision target, but it is one of many. Don't let it limit your possibilities.
