everyone knows that radio shack is giving away cue cats free, don't they? The cue cat is an optical reader used for reading barcodes. Inside the cat is a light sensor that might be useful for robotics. I think the light sensor in the cat is fairly (...) (25 years ago, 21-Nov-00, to lugnet.robotics)
