RE: Location Detection

oh hehe, nah definitly not a gumstix.  using a 2.8ghz machine.  the robot 
competes in the IGVC (inteligent ground vehicle compeition).  However though, I 
am starting to design a IRVC (inteligence race vehicle competition)with some 
friends on the robotics team here at University Missouri Rolla.  
We dont have a lot of funding right now since we are doing it on our own, so we 
are going to use an RC car for a chassis and use gumstix to do line following 
and object detection so that the cars can race and manuever around each other 
on a running track.  We hope to get a lot of other schools/people interested in 
it so that an annual competition can be held, like IGVC (igvc.org)

Are you controlling all of this with a gumstix/robostix or do you have
some other sort of microcontroller?

What kind of software do you use to interpret the stereo vision input
into 3D space?

I read your post here just after I sent my last one, my thoughts exactly.

Lots of good ideas, thanks.
