An AI racing robot wrote by me and my friend Miłosz Kosobucki as final assignment for Fuzzy Set Theory course (winter 2009/2010) at Faculty of Mathematics and Computer Science, Adam Mickiewicz University in Poznań, Poland.
It's written in C and uses The Open Racing Car Simulator (torcs.sourceforge.net) API. The robot makes heavy use of a fuzzy logic controller to calculate acceleration, steering and gear shifting behavior all in real-time.
