First Law: A robot may not injure a human being or, through inaction, allow a human being to come to harm
Second Law: A robot must obey orders given it by a human being, except where such orders would conflict with the First Law
Third Law: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law
The word robot was introduced into the English language from a 1921 play RUR (Rossum’s Universal Robots) by Czech playwright Karel Capek.
