Free, fall 2011 on-line class info:

And from the "father" of Stanley, (last seen being driven around by a new robotic car, across the Golden Gate Bridge).

Introduction to AI:

They'll have some support for multiple languages. Largely video based, and all free. You don't get a grade, but a certificate of completion.

Just for fun:
If you haven't seen the first DARPA autonomous vehicle race video from several years back, I'm sure it's still on-line. It's been shown on the TV a couple times at least. Wonderful stuff! Murphy's law had a field day. ;)
