Line tracking test

Yesterday we built a first version of the edge detection. The edge detection is able to detect a color change and store the states of the three lightsensors in one integer. Today we made a set up for the linetracking and implemented this. A first test was done and for a first test it was succesfull. The rover was able to track the line and count the length. However the were some problems with the hardware so the steering was not perfect. So next we are going to fix the steering in the hardware and also we are going to improve the algorithm for steering in the sofware. Movies of the line tracking will be post soon.
