We did too. Had to use Lego Mindstorms. It was a pain in the a$$ to program back then.

One of the guys built a very fast line-following robot, much faster than what we see here. It was simpler though, it was a solid black line.

I remember having to do the solid black line with a couple of photo-diodes and a small AVR in first year EE. Was kind of a neat project thinking back, but we all hated it at the time because it soaked up quite a lot of time tuning it aggressively to beat everyone else without losing the track, going back where you came from, etc!

luckily ours was arduino-ish and pretty simple to program. But we had to built everything since it was more of a mechanical + electrical design class, so there was lots of machine shop time
