I don't understand why you'd choose a wheel with such a wide 'grippy'
tire. You want the wheel to spin on the spot with minimum friction,
so wouldn't you want to use a large pulley with a thin tire?

| (...) Sure, you can make a caster with the pulley wheel and thin tire though I think it is a little less elegant. For one thing, since the pulley wheel is only 1/2 unit wide, it will slop around unless you use a longer axle and bushings on the ends (...) (22 years ago, 18-Mar-03, to lugnet.robotics)
