Given the extensive traffic concerning robot platforms, I thought I'd add my
two cents: For my senior project at Cal Poly I made a robot that had three
wheels, two of which were independently driven and one which was a small
caster. The chassis and wheels were machined out of plexiglass. I used
precision bearings and stub shafts from discarded computer disk drives to
support the belt driven drive wheels, and the tires were made out of
surgical tubing. The caster consisted of a section of aluminum angle iron
with a vertical shaft rotating in a plexiglass block and a horizontal shaft
with a precision bearing pressed on for the wheel. It was actually pretty
easy to build, and allowed excellent precision when making turns, rotating
on a vertical axis, and running straight ahead.
I am entertaining the notion of producing the chassis on a trial basis with
wheel base, length, drive ratio and ground clearance 'per customer request'.
If this produces any interest, please e-mail me for more information.
By the way, the DC motors in old floppy disk drives are an excellent choice
of drive motors for robots as they are of very high quality, run on little
current, and have integral shaft encoders. (cheap, too)
