Soccer Open is not a simple category. Either the teams bear with it, or they can drop to a less complex category. Last year, my team leader came to me and told me that I should make a functioning ball-detecting program on a Unix system. I was 13. All I knew was some basic Arduino and really basic python. In the 3 months that followed, I had to teach myself some pretty hardcore Object-Oriented Python, Bash and then C++. That year the robot didn't work. We where beat by a lot of pixy users (with the exception of one team). But in the end, we were much better off than them Yes, they won the second place, but they missed on 3/4 of the knowledge they could have gained.
It is a hard category, and it has to be made harder constantly. New Abstractions to robotics evolve constantly. In 2004 there was no "out of bounds", pretty rightfully, because it was hard enough to have a robot that followed the ball, especially since it was coded in Assembly/C. Today we have Arduino, Raspberry pi etc., etc.
A the transition from light to open is hard, teams then take a pixy and want to ease off the hard work that really pays off in the end, and then beg organizers for the removal of landmarks (yet another reason for the removal of pixies). And honestly, I think that last year it was totally fair that some of the local competitions had them removed. But the longer the landmarks are going to be there, the more I think they should stay there.
I have no say whether you will or won't remove the in your local competition, but I certainly think teams would miss out some very important struggles that should be there.
I am not saying that RCJ isn't for "kids", since I can consider myself as one, but I think that the rules shouldn't be simplified to make a simpler transition, since the struggle is an important part of the learning process.
