Hint: Wide + Short. :)
The wider the base is, and the closer the wheels are together front/back,
the less binding you'll have. If you have a very narrow design, that is
long, and you try to do A+B sterering you'll have virtually no success. When
the wheels are closer together forward/back, and you have them far appart
sideways, you're geting closer to creating a situation as if you had only
one wheel. See what I'm geting at? The wheels are therefore *almost* lying
on an axis which passes through the centre of rotation. When you've got a
long, narrow robot with wheels way far along the body, you're no where near
to that setup.
This is why daiOtoko, my sumo robot for Guelph, had a wide, but short, body.
Of course, there is no way to completely eliminate the skidding with 4 tyres
like this, unless you want to pivot them inwardly a few degrees, so that
their axis of rotation passes through the centre... and it wouldn't surprise
me if you actually *did* that. ;)

| (...) well, between the time i made the post and now i created a quick 4 motor 4 wheel design and to my surprise it worked. the A B steering is acceptable. there is some skitter, but not too bad. Thanks, I'll try putting distance between the motors (...) (24 years ago, 9-Nov-00, to lugnet.org.ca.rtltoronto)
