Introduction: The Substitution of Human Faculties with Technology: Computers and Robots With the development of modern computing, starting in the 1940s, the substitution of human abilities with technology obtained a new dimension. The focus shifted from the replacement of pure physical power to the substitution of mental faculties. Following the early 1980s personal computers started to attain widespread use in offices and quickly became indispensable tools for office workers. The development of powerful computers combined with progresses in artificial intelligence research also led to the construction of sophisticated robots, which enabled a further rationalization of manufacturing processes.

1940s - 1950s: The Development of Early Robotics Technology During the 1940s and 1950s two major developments enabled the design of modern robots. Robotics generally is based on two related technologies: numerical control and teleoperators. Numerical control was invented during the late 1940s and early 1950s. It is a method of controlling machine tool axes by means of numbers that have been coded on media. The first numerical control machine was presented in 1952 at the Massachusetts Institute of Technology (MIT), whose subsequent research led to the development of APT (Automatically Programmed Tools). APT, a language for programming machine tools, was designed for use in computer-assisted manufacturing (CAM). First teleoperators were developed in the early 1940s. Teleoperators are mechanical manipulators which are controlled by a human from a remote location. In its typical application a human moves a mechanical arm and hand with its moves being duplicated at another location.
