Ah, first of all these are some of those "really expensive" motors I was
talking about. Also, Piezoeletric motors aren't lik DC motors, you can't
just attach a battery and expect the motor to spin. While indeed the motors
are very small, they have a nice handsome peice of control circuitry that is
required to make them work properlly, so they really aren't ideal for BEAM
bot's.

All this talk of motors reminds me.
I read about this very small kind of motor they use in camera lenses, the
piezoelectric ultrasonic motor. I saw a picture of it, and it was indeed
extremely tiny...
So, what I was wondering is if anyone sells thses commerically, and if
so, would they be suitable for making REALLY small BEAM robots? I mean,
they look like they use very little energy, so they'd run great off a
solarengine, no doubt.
Another question:
Would one of those modified motors I was talking about work OK for say, a
walker? They're got lots of torque, so I was thinking they'd be perfect
for it. Mondotronics carries a few.
