That is right. It's not only a mere problem of area covering, but the
main objective is to have the robot locate the ball quite quickly
without a significative error. We tried at first with the same ball and
less LEDs and it was working, but the main problem remained the
inaccuracy of the light-following procedure. You have to find a
compromise between the fast movement of the robot and the precision with
which you want him to locate the ball: a higher number of LEDs leads to
much better results.
