Only information I could find on B2Bot by searching on Google was a brief caption on the
robot gallery page of the
old CMUCam site:
"Here is B2Bot, a robot with CMUcam on a servo head, two DC motors and a custom controller called Cerebellum that we are in the process of releasing now."
Here's what little information I can give you. If they were just releasing the Cerebellum board, that was probably the CMUCam 1. They're now up to the
CMUCam 3.
The
Cerebellum is out of production now, but was originally developed by
Botrics, a very small company spun out of the Carnegie Mellon University Robotics Club. While it may have been used by others, as far as I know it was only ever seriously used in-house. We still have a few of the gutted boards kicking around the Robotics Club room, in the bin appropriately labeled "controller graveyard."
If you're looking to create something similar, I'd suggest taking a look at the
SpoonBot build with the CMUCam 3. The faster processor on the new model allows both motor control and image processing to be done on the same processor. While those particular instructions don't include an independent pan mechanism, it should be easy enough to add one. Example firmware for the CMUCam 3 is also included in the available software package.
If your intention is to use a CMUCam 1 or 2 that you already have lying around, I'd direct you to Kevin Watson's website, where he has a
collection of documents about setting up and communicating with the CMUCam 2. The CMUCam 1 used similar protocols. The old CMUCam site also has links to
manual and
sample code for using the CMUCam 1 and
CMUCam 2.
Hope some of that is of use to you. If you're attached to the particular B2Bot project for some other reason, I would guess it's around 7 years old now, so it would probably be difficult to find someone that could help you. Sorry.
