I voted also yes

I made IA for NecroSPACE 2 (when you do a botmatch, rocks etc. have realy simple AI).
Currenly at school we have a little robot wich can wander around and create a map of what it has seen using a sonar.

Most part of AI (path finding etc. is already done when you buy the thing...)
