They had these cool electromechanical switches.

Instead of using electrical motors, electromechanical actuators, we're using compressed air.

We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency.

We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency.

So there was electromechanical systems, a good example of this actually was originally in phone systems.

It was an electromechanical rotor machine invented by a German engineer at the end of the World War I.

Those decisions take place many, many times, and the loop of environment feedback to sensors, agent decision, actuator interaction with the environment and so on is called perception action cycle.

And if we can actually provide feedback, sensory signals that go back from this robotic, mechanical, computational actuator that is now under the control of the brain, back to the brain, how the brain deals with that, of receiving messages from an artificial piece of machinery.

And we make a mathematical model of those relationships and program them into a tablet computer so that when you take the stylus and go and touch the screen, that voice coil actuator in the white bracket plays vibrations to give you the illusion that you're touching the real surface, just like if you touched, dragged back and forth, on the real canvas.
