Robot Challenge 7

Robot data recorder was challenge 7. in this challenge we had to use variables, the variables determined how dark the location was and would show up on the screen. The robot had to first move forward stop at a black line then continue to move forward into a box and once the robot detected the end of the box the robot would then come back out when it heard a  loud sound. We had one simple problem when doing this challenge, the problem was that our robot wouldn't stop on the black line we finally figured it out because we made a simple mistake in our code.
