	[talking about motors and building a base]

   I took two of these an bolted them together using threaded rod (the ='s) and
   spacers that I got at the hardware store, using four of the mounting holes
   (one in each corner). Then I extended (E's) the axles and added wheels (W's).

if you build this just inverted and increase the size of the wheels,
as in the following diagram:

      WWW           ##        ##	   WWW
      WWW          =##========##=	   WWW
      WWW				   WWW
      WWW				   WWW

then if you hang the batteries low, you can get with just two wheels.
this makes turning a snap and lends the robot a very interesting demeanor.
