Put in turbo mode. Draw the path. Press 1 for marker and 2 for eraser. The marker is the obstacle. Wait a while for them to learn. Press the spacebar to reset the drawing. Some things to keep in mind when making a track: Don't make too sharp of turns, they will be impossible for the AI to do. The AI has only 6 sensors, so AI will not see really small details and might not be able to complete complex tracks. Also because of the way the sensors work, they only detect the colour black; they do not detect the edge of the project screen. For information on how this works, see the original by me (Yes, I remixed my own project. No, it's not hacking).
