Pneumatics

• Uses compressed air to push things around
• The air gets piped around in tubing, stored in
  air tanks, and released using a device called a
  solenoid
• Much better at linear motion than electric
  (rotation) motor
• Very strong, fairly fast
• Not accurate

3
Parts

• Compressor
• Air Tank
• Piston
• Tubing
• Solenoid
• Various valves/connectors/gauges

4
Compresses Air

• Gets power from a spike plugged into a 30 Amp
  slot and connected to the sidecar
• Shakes a lot, and makes a buzzing noise- bolt it
  down
• Tubing from it leads to the valves, and then to
  air tanks

5
Accumulator/Air Tank

• Stores Air.
• That's why we call it an air tank.

6
Solenoid

• Controls air flow is wired to the digital sidecar

7
Piston

• Uses compressed air to propel a metal rod out of
  a cylinder. This can technically be used to spin
  an axle (e.g. in cars), but it's more efficient
  to just have it go straight in and out.

Air Tubing

• Flexible tubing that lets air through
• Kinda self-explanary

10
Brass Connectors

• Various brass connectors that screw into things,
  and allow the tubing to be attached to parts

11
Regulator

• We can store air at 120 psi, but only use it at
  60psi.
• In between, we have regulators, which regulate
  the air supply (as you might have guessed)

12
Gauges

• Lets us see what pressure is inside.
• Therefore, must be visible
• One on each side of the regulator(s)

13
Pressure Switch

• Sends data back to the digital sidecar, which
  lets it be programmed to control the pressure by
  turning on and off the compressor.
• PWM needs to be specially cut- ignore the black,
  redwhite go on opposite prongs
• Goes on high-pressure side of the regulator

14
Vent Valve Thing

• Allows us to manually release all the remaining
  air in the system
• Should be beside a the pressure switch and a gauge
