Robotics is an interdisciplinary branch of engineering and science that includes mechanical engineering , electronics engineering , computer science , and others. Robotics deals with the design, construction, operation, and use of robots , as well as computer systems for their control, sensory feedback , and information processing .
Technological unemployment is the loss of jobs caused by technological change . Such change typically includes the introduction of labour-saving "mechanical-muscle" machines or more efficient "mechanical-mind" processes ( automation ). Just as horses employed as prime movers were gradually made obsolete by the automobile, humans' jobs have also been affected throughout modern history . Historical examples include artisan weavers reduced to poverty after the introduction of mechanized looms . During World War II , Alan Turing 's Bombe machine compressed and decoded thousands of man-years worth of encrypted data in a matter of hours. A contemporary example of technological unemployment is the displacement of retail cashiers by self-service tills .
A medical robot is a robot used in the medical sciences . They include, but are not limited to, surgical robots . These are in most telemanipulators , which use the surgeon's actions on one side to control the "effector" on the other side.
An articulated robot is a robot with rotary joints (e.g. a legged robot or an industrial robot ). Articulated robots can range from simple two-jointed structures to systems with 10 or more interacting joints. They are powered by a variety of means, including electric motors .
