To build a fully autonomous robot capable of following two parallel white tracks against a black background and report the errors (if any) in the laying down of the tracks.The errors can be of two kinds:
- The width of the track (i.e. the distance between the two white lines) is less than or more than the correct width of track.
- One of the tracks (i.e. one of the two white lines) is broken.
Note that both errors will not happen simultaneously.
