I'm working on a design for a robot base that will support a robot about 
18 inches round and 30 inches tall. I would like to know if 2 wheels with 
a caster or 3 wheels without is better? What method is usually used to 
link up stepper motors to wheels and what about part sources? In the past 
I've experimented with stepper motors and worm gears and have had 
troubles with mounting and placement. Any books on the subject 
(mechanical engineering of wheels, gears, and motors?) would be helpful. 

I would be interested in hearing from anyone out there that has 
successfully built a robot base using stepper motors and gears that 
resulted in enough torque. Please respond here or email me. Thanks!
