In science fiction, the Three Laws of Robotics are a set of three rules written by Isaac Asimov, which most positronic (a fictional device) robots appearing in his fiction must obey.
The laws are:
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
Loopholes in the laws
Laws had been deliberately misrepresented because robots could unknowingly break any of them.
1. Robots may not aware of the nature of their tasks; for instance being ordered to add something to a person`s food, not knowing that it is poison.
2. A clever criminal could divide a task among multiple robots, so that no one robot could even recognizes that its actions would lead to harming a human being.
3. If a spacecraft was built with a positronic brain, and carried neither humans nor even the life-support systems to sustain them, the ship`s robotic intelligence would naturally assume that all other spacecraft were robotic beings. Such a ship could equip to slaughter humans.
Dr. Isaac Asimov was a Russian-born American author and biochemist, a highly successful and exceptionally prolific writer best known for his works of science fiction and for his popular science books.
Movie based on Three Laws of Robotics (I, Robot)
It`s the year 2035, and the community now has the help of robots. These robots have three laws integrated into their system. One, they cannot harm a human being or, through inaction, allow a human being to come to harm. Two, they must do whatever they`re told by a human being as long as such orders don`t conflict with law one. Three, they have to defend themselves as long as such defense doesn`t conflict with laws one or two.
One day, the writer of the three laws, Alfred Lanning, apparently jumps out of the tenth-floor window of U.S. Robotics. The majority of the Chicago Police Department believes that he committed suicide, but Detective Del Spooner (Smith), who hates robots, thinks he was murdered, and the number one suspect is a Nestor Class-5 robot who calls himself Sonny.
However, if it was Sonny, then that means he would`ve had to have broken the three laws. With the help of Dr. Susan Calvin, Spooner must now discover the truth before it`s too late.
