大家看看这个走迷宫的循迹机器人，这反应速度，真是快。

This was my first attempt at making a maze solver and I wrote the code from scratch the night before our last local robotics competition, so there's plenty of room for improvment (for example, it would be cool if it could handle mazes with loops or irregular intersections). It would also be cool if it could have similar performance with higher robustness (changing conditions such as harsh shadows or dusty tires can really throw it off at the moment).
It uses PID control to follow the lines and it makes pre-programmed, timing-based turns once it has identified which way it wants to go at a given intersection. Because of this, it's kind of at the limit of what it can do with current programming; if I push it much further it starts to miss intersections or think the ending circle is an intersection, at which point it turns left and drives around the outside of the circle. As it is now, it's so finely tuned that it only functions with clean tires. In the video, on the fast run, you can see it start to fishtail on some of the turns just from the dust the tires picked up on the learning run (normally I use some rubbing alcohol to clean the tires before every run, but I figured that would be pretty boring to put in the video).
