Challenge 3

Day 24: I liked this challenge. It was simple, but challenging. The robot itself was fairly easy, once I got it to stay together. What was more difficult was the program. Getting it to run and stop was fairly easy, although there was some trouble that Mr. Bell helped me fix today with getting the sensor to only sense the black strip at the end, but not shadows. The most difficult part of the challenge was getting the robot to calculate how far it had traveled. With Mr. Bell's help though, I figured out the calculations and got the robot to calculate them. I later had to make an altercation when the wheels rotated without moving the robot on the stairs. I probably should have thought more about the light sensor problem, but other than that, I think I did fairly well.
