Aie.  How about we evaluate the actual functionality of this motor
before going and buying yet another motor with unknown suitability.

Don't forget that the computer can make the motor run very slowly
through appropriate control...

I think 15V is a safe voltage to apply to our motor if torque is a
problem.  15V should (theoretically!!) result in a 25% torque increase.
This puppy has decent torque already.  Our little boy can do some
serious shaft work.

As soon as you are in simultaneous contact with a weigh scale and
with appropriate robot parts, weigh the following:

	1) the motor
	2) the Lexan base
	3) the weight of a hunk of Lexan of known area: this may
	   correspond to the Lexan base
	4) the weight of say 10 AA batteries

My preference.  It is _our_ primary, so if it is too full, we should
get priority over other groups, anyways...
