All pneumatic systems start with an aircompressor. This compressor is usually rigged with a electronic pressure switch, which shuts the compressor off once the system has reached pressure. The compressor uses an accumulator to store additional compressed air in reserve in case the amount of air required by the system exceeds the compressor's output. Both of these components are connected to an air regulator, which reduces the combined compressor and accumulator output pressure to the desired psi (usually pressure gauges are placed before and after the regulator). This resulting air feed is then connected to a series of mechanical or electric solenoids (air valves). Two lines run out of each solenoid, each connects to an opposite side of the pneumatic piston (s) that the solenoid controls. When triggered, the solenoids direct the air into the front or back of the piston depending on the desired direction of the piston. Return air from the opposite side of the piston is usually vented. This results in the pneumatic pistons emitting a hissing sound whenever they are moved.
A - Compressor: a pump which compresses air, raising it to a higher pressure, and delivers
it to the pneumatic system (sometimes, can also be used to generate a vacuum).
B - Check valve: one-way valve that allows pressurized air to enter the pneumatic system,
but prevents backflow (and loss of pressure) into the compressor when it is stopped.
C - Accumulator: stores compressed air, preventing surges in pressure and relieving the
duty cycle of the compressor.
D - Directional valve: controls the flow of pressurized air from the source to the selected
port. Some valves permit free exhaust from the port not selected. These valves can be
actuated either manually or electrically (the valves typically provided in the FIRST kits use
dual solenoids to change the direction of the valve, based on input signals from the control
system).
E - Actuator: converts energy stored in the compressed air into mechanical motion. A
linear piston is shown. Alternate tools include rotary actuators, air tools, expanding
bladders, etc.

Almost anything that would be considered a robot has the following basic elements:A moveable body -- Robots may have wheels, limbs connected by mechanical joints, or other types of moveable segments.An actuator -- In order to be activated, robots may use an electric motor, a hydraulic system, a pneumatic system or a combination of all three.A power source -- A robot needs a power source to drive its actuators. Electric robots use batteries or extension cord. Hydraulic robots need pumps to pressurize the hydraulic fluid, and pneumatic robots need air compressors.An electrical circuit -- The electrical circuit powers the electric motor, solenoid or valves that control hydraulic or pneumatic systems.A reprogrammable brain (computer) -- The computer controls all other components. In order to change the robot's behavior, you just have to reprogram the computer.A sensory system -- Some robots have the ability to collect information about their environment and react to it.not written by me but found
