Rumble Robot Bar Coding

A few years ago, a popular toy was the Rumble Robot that used bar coding as a data input.
Has anyone figured out what the bar coding was so one can reprogram the
robots?
Thanks

I'm not sure anyone bothered, as these robots were fairly unimpressive when it came to their programmed play. It would probably be easier to stick in a small PIC or AVR. I've seen some Rumble Robots "autopsy" sites here and there, but it's been a while.

I once looked at the barcode for these and felt there were too few data for actual coding. I think the only information contained on them is an identification of the invidual robot, a "level" of some type (like power), and an action. The programming is already in the little blob micro on the main board, so at best all you can do is input different combinations of what's already there. I seriously would doubt you can add anything new.
Not that trying to hack the code isn't interesting in itself, just that once you do I'm not sure what the prize will be when you get there! The mechanicals of these things are great, though.
