Hello there
i wanna ask about level of processing for the AVRCam and CMUCam(Do cams do any kind of processing on the taken images)
and What is the type of the data that AVR and CMU sends (e.g. coordination, position, direction)?
waiting for the answer
have a nice time

    There's lots of documentation on both devices that goes into detail on what you can get from the cam. You should download and read the manuals first, then ask about anything you don't understand.

    Here's the AVRcam page: www.jrobot.net/Projects/AVRcam.html

    Here's the CMUcam start page: www.cs.cmu.edu/~cmucam/

    The manuals are pretty explicit about what the cameras provide. They're intended primarily for educational purposes, so there's a lot of information that comes with them. What other information do you need and why?

    Again, read the manual. The AVRcam documentation lists all the commands that the cam will respond to and shows the exact response from the cam for each command. The CMUcam comes in 3 different versions and the manuals for each have even more detail on what you send to the cam and what is sent back.

    The AVRcam essentially has two capabilities. 1) It can provide a "dump" of the screen contents, essentially a "snapshot". 2) It can track up to 8 "blobs", areas of specific color that you specify and continually report the coordinates of the centroid of the blobs.

    The original CMUcam was similar. The latest version has a interpreter for the programming language LUA and can control several servo motors based on the tracking information. Read the CMUcam3 manual for the details.
