Disinclined to shimmy up tall trees to replenish his bird feeder, Fred devised an electric cable-and-pulley system to reel it in. Using a modified garage door opener, he controls the motion of the feeder, which travels 50 ft between his house and tree via a single loop of steel cable and series of pulleys driven by a motor and worm gear unit. The feeder hangs from both cables, with an idler pulley on the top cable and cable clamps on the lower cable to reduce stress and swinging motion. And Fred keeps his feet firmly on the ground.

Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
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.
