So Larry installed a 12V motor with a cable shaft in the attic and attached the cable to the door. Limit switches stop the motor when the door is fully open and closed, and a converter ensures the correct voltage to the motor. Larry can now activate the door from the bottom of the stairs.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
