Hey peoples! OK, I want to make a robot for a science fair that has some sort of AI , at least enough to navigate around obstacles. I've never made a robot before, and I have practically no knowledge of the related topics. I am smart and willing to learn, so help of any kind is appreciated! Also, being in 7th grade I have NO source of income, so any tips on how to be super cheap on parts would help. Thanks for your time! Please help!
