I remember working on a #linefollow #robot for an #undergraduate #course at #university - I essentially ended up developing some kind of very #hacked " #neuralnetwork ": https://hackaday.com/2021/09/18/line-fol.. I hadn't really learned about #pid at this point, but after some time I started to #reinvent the idea of a #pid #controller from scratch. It's really great when we can come to the same conclusions through different methods!
