Re: Visual of the Robot on the Competition Field
2015, 2016, 2017, and 2018 have all had significant visibility issues. I find it hard to imagine any driver or coach from those years saying that they have never had a problem with not being able to see the robot. And unless you're driving the robot virtually (i.e. not by sight), that is bound to inhibit your team's performance.
I imagine this survey is preceding either some kind of product release or a petition for FIRST to get rid of tall field-elements. I'll reserve judgement until that comes out.
