In this interactive activity adapted from MATEC, learn about pneumatic actuator systems, which use compressed air to transmit motion. Animations illustrate the components of a typical pneumatic actuator system: the computer, communication module, programmable logic controller, input/output module, solenoid valve, and pneumatic device. Observe how the system functions as a whole, and learn more about some common pneumatic devices.The interactive is accompanied by a background essay, standards alignment, and discussion questions.
