2.  What are pneumatics?  What are pneumatics good for?  How pneumatics work  The pneumatic system  Variations on the theme

3.  Mechanisms which use air pressure to apply mechanical force and displacement (work)  The pneumatic devices we use are basically binary actuators – either retracted or extended Retracted Cylinder Extended Cylinder

4.  Mechanisms requiring (2) discrete states  Gear shifters  Gripper articulation  Lifters  Brakes  …and a significant force or displacement

6.  Simple

7.  Easy to control

8.  Simple  Easy to control  Can apply a lot of force from a small, light package

9.  Simple  Easy to control  Can apply a lot of force from a small, light package  Force is limited by air pressure and cylinder diameter

10.  Simple  Easy to control  Can apply a lot of force from a small, light package  Force is limited by air pressure and cylinder diameter  No adverse consequence if cylinder is stopped (no stalled motors) or reversed – compressed air is a spring

12.  A significant weight “investment” (~10 lb m ) in a pneumatic system is needed for the first pneumatic device

13.  Cylinders can be subject to damage

14.  A significant weight “investment” (~10 lb m ) in a pneumatic system is needed for the first pneumatic device  Cylinders can be subject to damage  Repair impossible

15.  A significant weight “investment” (~10 lb m ) in a pneumatic system is needed for the first pneumatic device  Cylinders can be subject to damage  Repair impossible  Not well suited for non-binary actuation

16.  Pneumatic actuators are extensively used by the Chemical Process Industry due to their intrinsic safety and their ability to fail safe (w/ spring return) 2-position pneumatic actuator driving a 4-way ball valve pneumatically driven flow control valves (butterfly type)
