The Physics of Pneumatics.

Pneumatics are very convenient Lego pieces: They are relatively strong (we will see how much later), and relatively light. As such, they can be placed at the extremity of an arm without problem (a motor might be to heavy). The hoses being flexible, it is easy to position a pneumatic to your liking.

In order to use them efficiently, you should know your pneumatics with a little more details. Here are some of the questions that will help you use them better:

  1. How to create the necessary pressure in the hoses;
  2. How to regulate the pressure;
  3. How to measure the strength of a pneumatic;
  4. What is the reaction time of a pneumatic;
  5. How to turn on/off a pneumatic.
 

Soh did some wonderful pages on pneumatics and how to measure their strength. Ralph Hempel have some great designs for the content of sections a. and b. See links on my main page.
