The physics of Lego motors

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.

  1. How to know the strength of a motor?
  2. Connecting two motors together
  3. Making a stepper motor
