How do the animations work?
Most animations work using the same principle of how a piston in a car’s engine works. A motor turns an arm on which a rod is loosely fastened. As the arm turns around, it pulls and pushes the rod back and forth. The Amishmen sawing use this principle, as do bulldozers, rollers, graders, and the like. There are many more complicated animations on the display that use chain drives, industrial slide rails, gears, pulleys, micro switches, relays and timers.
