I would reccomend just lining up the robot with one side touching the wall and let your programmer take it from there. From the camera posistion you can aim you cnnon(whatever shoots the ball) and using the gear tooth counters you can get yourself to a posistion on the field with relative accuracy. THat is how 75% of the teams will do it this year(some may just count loops rather than using sensors) It has proven effective in the past and makes lining up you bot very fast and easy. With a gun sight you run the risk of damaging the sight or having it bumped ruining the accuracy. If you have every shot a gun with a scope you have likly realized that if it gets bumped a little then it will ruin the accuracy, there is more than a little bumping on the field. Just because it is allowed does not make it a good idea.
