Go to Post Teams rarely win FIRST events because they can complete actions that nobody else can; they win because they do things faster than others. - Madison [more]

Line following should be much faster this year. The problem with line following last year is that the robot controller was so slow (~40 Hz sample rate) that you could easily move 3 inches per sample with a fast robot. You would blow by the line and not know it. Therefore, you needed to slow your robot down in order to do it.

With the new controller, you have a much faster sample rate, which means you won't go nearly as far in one sample and therefore correct much faster.

If you really want to be slick, use an array of optical sensors (say 8 of them in a line). Then you can use a feedback loop to try and keep the line in the center of the array. This way, your follower is more analog, rather than digital.
