Pneumatics is responsible for the compression and transportation of air pressure throughout the robot. The air, which starts in the compressor, goes through a series of regulators and valves that guarantee safe use of the air. It then travels through pneumatic tubing to its final location, where it is used to activate and retract pistons. These pistons can be used in a variety of functions, including gear shifting and extending parts of the robot.
The advantages of using pneumatics on a FIRST robot are numerous. A major advantage comes from the speed that pneumatic pistons can move. This, combined with their ability to deliver a large amount of force to a localized area, allow pneumatic pistons to perform a large variety of functions. Pneumatic pistons also come in many different sized bores (diameter of the piston) and strokes (length of the extendable shaft), which adds to their versatility.
Tips for Rookies: A pneumatic system, if not built perfectly, will leak. You can check for leaks by taking a cup of soapy water, and dabbing soap on connections that you think may be leaking. If the water bubbles up, the connection is leaking. This can be done much quicker than just feeling for leaks with your hand. Pneumatic tape must be applied to all connections; if applied incorrectly, it will leak. If a leak is found, you should undo the connection, re-tape it, and re-attach it to the system.
