I have two plans for teams not having much luck with their cameras, both involving use of gyros and encoders. Your first option is to have your autonomous dedicated to blocking opposing blocking bots (Obviously I "borrowed" this idea). This is a good plan because the very good teams will likely have camera autonomous and will find you to be a valuable partner. The other plan is to have an arm with an aluminum tetra shape on the end, and two three way switches, one to select your starting location, and the other to select a goal which your robot will then drive to and put its aluminum tetra on top of for the duration of autonomous (It would be a part of the arm, not something it sets there then leaves obviously). Not only is this a more GP way of blocking than simply careening about with the intent of destroying, but it should also be moree effective. If you were really good you could even have a giant folding arm that covers all three goals
