Thanks so much! I never showed my students that diagram because though I found that paper as well, I could see the diamond or "o" pattern but the vectors didn't look like I thought they should. Shouldn't the vectors be the same even from the carpet? I am very rusty on this stuff. Last fall when we started research we referred to your posts and info on the charateristics of Mecanum drives, but it doesn't sink in that well for me. Thanks again.
