- Air! A pneumatic assembly is one that converts energy stored in compressed air to mechanical energy. Electrical Energy Compressed air Mechanical force Compressor Release of air
- Slide 3
- False! Tiny investment, major returns Requires only some heavy components Pneumatics are usually very light in comparison to motors! No heavy motors No gearboxes No sprockets, etc.
- Slide 4
- FIRST made the rules much nicer this past year. Unlimited air storage Much lighter compressor
- Slide 5
- Putting into motion Motors rotate, cylinders extend and retract Good in different situations Motors Pneumatics
- Slide 6
- Pneumatics good for fixed distances of travel Motors good for infinite travel Examples: Raising and lowering arm: fixed Extending and retracting arm: fixed Driving infinite Operating a belt infinite Spinning a wheel infinite Opening and closing a claw - fixed
- Slide 7
- Slide 8
- Slide 9
- Pneumatics are not heavy! If you need infinite motion, use motors. If you need a fixed distance of travel, use pneumatics. Dont try to use one for the other!
- Slide 10
- How to build them!
- Slide 11
- New (Rookie) Compressor Old Compressor
- Slide 12
- Simple Concept stores air Unlimited quantity
- Slide 13
- FIRST requires that: Max storage pressure: 120 psi Max working pressure: 60 psi Regulator does that! In line between tanks and cylinders
- Slide 14
- What actually does the moving!
- Slide 15
- Bore Diameter: The diameter of the bore (inside) of the cylinder. Increasing this increases force applied by the cylinder, but also increases air used. Stroke Length: The distance the piston travels when extending or retracting. Increasing this increases air used.
- Slide 16
- The valve that controls air flow Electronically controlled 2 types Single-solenoid Double-solenoid
- Slide 17
- Tubing Brass fittings Safety pressure release valve Tube connectors Pressure sensor Teflon tape
