Robonova with a cmucam2

I have just been playing with a CMUCAM2 and I think the best way to interface it would be via another micro - perhaps a small AVR board.
This could process the CMUCam data and provide a much more simple output - maybe via 2 D/A channnels into the RoboNova analogue inputs.
Maybe as simple as the x and y location of a tracked colour blob or motion detected area.
Seeing as neither the RoboNova or the CMUCAM are open source, it's the only way to make the thing autonomous without sending the data back to a PC to process. (If you used a PC, you'd just send a video feed direct).

This is a very good idea. In fact, the code already exists, in part, at the downloads section found in the Parallax Inc. web site. The CMUcam-1 sends tracking information to BoeBot, which in turn moves the wheels to acquire and track the object. In RN, we replace the wheel turning code with a foot turning routine in the proper direction, then execute a walk forward routine. An infrared or Ping))) sensor determines the "follow distance."

Hi, I have a CMUcam2 from seattlerobotics ... basically it's a piece of work to use so I switched to the POB-Eye system from POB-Technology it's much more intelligent and so much easier to use being that you can program it in BASIC, Java or C languages ...
The libraries for the POB-Eye allow easy programming for recognizing colors or objects ... and so can make your robot so much more functional than just following blobs of colors ...
I highly recommend buying the POB-Bot "Golden Pack" as a start ... play with that and then move the big-buck items over to your RoboNova-1 after you've gotten comfortable with POB-Technology ...
So far there are at least three different POBified conversions of the RoboNova-1 and the latest seems pretty keen ... but this one here isn't bad either ...
On my RoboNova-1 I stuck the POB-Eye inside the chest plate:
I've been contemplating a new thicker body for the RoboNova-1 that would completely encase the new POB-Servo and controller ...
