The word “Robot”comes from the word “Robota”,meaning, in Czech”, forced labor, drudgery.
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 the 1940s.
The Three laws of Robotics
Asimov also proposed his three "Laws of Robotics", and he later added a “zeroth law”.
Zeroth Law : A robot may not injure humanity, or, through inaction, allow humanity to come to harm
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 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.
The First Robot “UNIMATE”
Unimate was the first industrial robot.
Developed for General Motors.
It was created by George Devol in the 1950s using his original patent filed in 1954 and granted in 1961.
The machine undertook the job of transporting die castings from an assembly line and welding these parts on auto bodies, a dangerous task for workers, who might be poisoned by toxic fumes or lose a limb if they were not careful.
The original Unimate consisted of a large computer-like box, joined to another box and was connected to an arm, with systematic tasks stored in a drum memory.
In 2003 the Unimate was inducted into the Robot Hall of Fame
