AWOL:
try sitting in the driver's seat.
Look around, then close your eyes, engage drive and steer based on what you just saw. Drive for about twenty seconds, then open your eyes. Repeat.(20 seconds is being generous)
Good point; was not thinking there would be such a long delay. Arduino has been a lot of fun; really helped me learn lots of new stuff, but I guess video capture/processing is too much and I might have to look at something else. Any leads ... ?
