So here's my contribution... a $12 tethered robot, or a $30 fully-auto robot that kids can build and take home. You don't need to buy a kit or system unless you want to.

That's a fantastic project outline. Exactly the sort of thing I was looking for. Thanks for sharing! I would really like to do this sort of thing in my class. I don't have full shop facilities here but I think I can do a similar project, perhaps with less custom fabrication. I'd like to do discrete component line following also.
