After starting, select any of the 3 lines. The robot follows the line and shows his trail with a green line. At the same time, he is recording his positions, which allows the path to be "replayed." The replay is shown in red. Following the line is not very fast in tight corners. However, the replay is fast, because each movement is to the next xy coordinate. V2 introduces the ability to "tune" several parameters to help improve on your overall elapsed time. The "All 3" option runs the robot over all three courses, computing the total elapsed time.
The original line following has been sped up slightly to move at 3 steps.
