Beforehand we were quite confident of ending in the top 3 of best line trackers. The last couple weeks our line tracker performed well with all sorts of tape and surfaces; it could measure the line with 1 mm accuracy every time. However, today before the competition, somehow we could only measure the line with 4 mm accuracy. We could not find an explanation for it, but we have listened to the advice of Marcel Verhoef: do not change your code just before the competition. With fingers crossed we saw our line tracker ending up first with an error of 4 mm (as we already expected), because the only group that outperformed us did not code beeps at start and end. We have measured 735 mm, while the true length was 739 mm.
So the first prize, one crate of beer, was ours to keep. Cheers!
