This robot is based off of the classic herbie schematic.
It is powered by a rechargable phone battery I found
for about $1.00 at a local Wal-mart.  They were a
good buy so I bought them all. Can never have too
many parts.  Anyway, the rest of the circuit is fairly
standard.  The frame is built using square brass tube,
and the motors are epoxied on because they couldn't
be soldered.
