These two sections are meant to understand what is the power of a
motor. Lego motors are reasonably powerful, yet, you cannot expect from
them to lift a car! It is important to understand this limitation, and
to build robots that takes full benefit from what is available.
The first section indicates how to measure the strength of a motor, and
what Lego motor is the most powerful. The second section gives tips if you
ever plan to connect two motors in parallel, so that you -it is hoped!-
increase the power of your robot.
