Click here - if you scroll down a bit, you will see the file card/brush that Beatty is using to crawl across the carpet... on each side there are six of these file cards - three in a row, two rows - on each side; or twelve file cards total. From what I have seen, Beatty
cannot go in reverse. They can barely turn, if they can turn at all. Maybe someone from the team could give a little insight ...
