"Robots are able to perform a variety of tasks that humans otherwise could not perform. Since the first robot, Unimate, was installed into a New Jersey General Motors factory in 1961, increased automation on the assembly line floor has boosted production levels to those that would be impossible with humans doing all the tasks. Today, factories of all kinds use robots to perform tasks such as welding, assembly, sealing and operating dangerous tools. The other advantage to robots is the fact that, as mechanical apparatuses, they never tire; so they can perform their jobs nonstop, turning manufacturing and industry into 24-hour facilities".
Learning Robots
It took just a few decades for computers to evolve from room-size vacuum tube–based machines that cost as much as a house to cheap chip-powered desktop models with vastly more processing power. Similarly, the days of "personal robots"—inexpensive machines that can help out at home or the office—may be closer than we think.
