Robotics is that branch of technology which the designs, construction, operation, and application of robots coupled with computer systems for their control, sensory feedback, and information processing. Very often the design of a given robotic system brings together principles of electronic engineering, mechanical engineering and computer science (artificial intelligence in particular).
Science-fiction author Isaac Asimov is often given credit for being the first person to use the term robotics in a short story composed in the 1940s. In the story, Asimov suggested three principles to guide the behavior of robots and smart machines. Asimov's Three Laws of Robotics, as they are called, have survived to the present:
1.Industrial Robots -These consist of robots used in an industrial manufacturing environment. Usually these are articulated arms specifically developed for such applications as welding, material handling, painting and others.
2.Domestic or household Robots -Robots used in the home like vacuum cleaners, robotic pool cleaners, sweepers, gutter cleaners and other robots. Also, some surveillance and telepresence robots could be regarded as household robots if used in that environment.
3.Mobile Robots-Mobile robots are able to move, usually they perform task such as search areas. A prime example is the Mars Explorer, specifically designed to roam the mars surface.
4. Articulated Robots-Used for assembly operations, diecasting, fettling machines, gas welding, and arc welding and spray painting. It’s a robot whose arm has at least three rotary joints.
5.Military- Robots-Robots used for the military include those used for bomb disposal, transportation and drones.
6.Entertainment- Robots -These are robots used for entertainment. Toy robots obviously fall into this category, but so do alarm clocks and motion simulators.
7.Mechanics-In contrast with expensive big robots BEAM robots are cheap, simple, built out of recycled material and running on solar energy.
8.Calibri (Body)-Robots on legs are usually brought in when the terrain is rocky and difficult to enter with wheels. Robots have a hard time shifting balance and keep them from tumbling.
