I've considered that concept, but I wanted to avoid a variation of line
following.
In real racing, drivers go full throttle until a specific braking point.
the faster riders generally brake later without screwing up the corner By
defining the boundries this gives the AI a little more leeway for selecting
different lines around the course. I invisioned a program that checks its
own laptimes and adjusts its braking, acceleration and steering accordingly
to optomize its lines just like a real racer. I selected an oval because of
its simplicity and Im sure Ill have some light sensor issues to deal with.
I think this will be a project well suited for fuzzy logic.
Thanks for the suggestion and the link, BTW Steve, you are my hero for the
Legway!
I will be building a table and bot-mobiles to test the concept. I will keep
you updated. please feel free to send me any suggestions or try it
yourselves.
