Ideas - The Laws of Robotics
by Isaac Asimov

These laws, known as "The Laws of Robotics," were introduced by a famous author named Isaac Asimov in 1942 CE.

LAW 0	A robot may not harm humanity, or, by inaction, allow humanity to come to harm.
LAW 1	A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
LAW 2	A robot must obey the orders given to it by human beings, except where such orders would conflict with the first law.
LAW 3	A robot must protect its own existence, as long as such protection does not conflict with the first or second law.

Isaac Asimov has made minor alterations to these laws in various books and short stories he's written to further develop how robots might interact with humans and other robots, and added a fourth law (more famously known as the "zeroeth law"), which is why these laws are commonly referred to as "The Three Laws of Robotics" despite there being four.
