I've become really interested in doing motion tracking for robots. CMUcam is cool, but I like trying to make things. it's cheaper and more rewarding I think.

I saw this http://www.makingthings.com/products...eo_user_guide/
on the net, it's a motion trackign circuit based off a pic. just plug in 1 or 2 cameras and it makes a 16x12 array to track changes! pretty freaking cool becuase unlike CMUcam, you could plug any camera in you want, eg infrared, nightcam, underwatercam, tv signal...

but I can't see what the two chips are... one is a pic, but there's something between the video connector and the pic.

any ideas??
I'd love to build a device for motion tracking.
