We experimented with using the camera to detect distance to the target/ball, but it just isn't accurate enough (can someone correct me?). You can use dead reckoning, i.e. drive for a certain period of time and then stop since you can place the ball where you want, or you can use a sensor. Some teams are using ultrasonic sensors or IR sensors. The control system documentation goes into how to use an ultrasonic sensor for this purpose.
