  What is aRobot…? A re-programmable, multifunctional, automatic industrial machine designed to replace human in hazardous work. It can be used as :- •An automatic machine sweeper •An automatic car for a child to play with •A machine removing mines in a war field •In space •In military , and many more..

  Robotics is scienceof designing or building an application of robots. Simply ,Robotics may be defines as “The Study of Robots”. The aim of robotics is to design an efficient robot. Robotics is needed because:- •Speed • Can work in hazardous/dangerous temperature • Can do repetitive tasks • Can do work with accuracy

  The word robotwas introduced to the public by Czech writer Karel Capek(1890-1938) in his play R.U.R. (Rossum's Universal Robots), published in 1920. The play begins in a factory that makes artificial people called robots . Capek was reportedly several times a candidate for the Nobel prize for his works . The word "robotics", used to describe this field of study, was coined accidentally by the Russian –born , American scientist and science fiction writer, Isaac Asimov(1920-1992) in 1940s.

  Asimov also proposedhis three "Laws of Robotics", and he later added a “zeroth law”. First Law : A robot may not injure a human being, or, through inaction, allow a human being to come to harm, unless this would violate a higher order law Second Law: A robot must obey orders given it by human beings, except where such orders would conflict with a higher order law Third Law : A robot must protect its own existence as long as such protection does not conflict with a higher order law.

  Mobile robots areof two types…. Rolling robots have wheels to move around. They can quickly and easily search. However they are only useful in flat areas. Robots on legs are usually brought in when the terrain is rocky. Most robots have at least 4 legs; usually they have 6 or more.

  Robots are notonly used to explore areas or imitate a human being. Most robots perform repeating tasks without ever moving an inch. Most robots are ‘working’ in industry settings and are stationary . Autonomous robots are self supporting or in other words self contained. In a way they rely on their own ‘brains’.

  A person canguide a robot by remote control. A person can perform difficult and usually dangerous tasks without being at the spot where the tasks are performed. Virtual robots don’t exits In real life. Virtual robots are just programs, building blocks of software inside a computer.

  Going to faraway planets. Going far down into the unknown waters and mines where humans would be crushed Giving us information that humans can't get Working at places 24/7 without any salary and food. Plus they don't get bored They can perform tasks faster than humans and much more consistently and accurately Most of them are automatic so they can go around by themselves without any human interference.  People can lose jobs in factories  It needs a supply of power It needs maintenance to keep it running . It costs money to make or buy a robot
