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)
  New "Designer Sets" such as 4099?
 
Are there any new and robotically-useful pieces in the new "Designer Sets" such as 4099, 4100, 4101, etc? (It's a bit hard to tell from the small photos) (URL) CatID=&OrderBy=0 Thanks Bruce (22 years ago, 18-Mar-03, to lugnet.robotics)
