Isaac Asimov’s Three Laws of Robotics were originally developed as a fictional ethical framework to govern the behavior of robots in his science fiction stories. By framing robots as entities programmed with inherent ethics rather than as "marauding metal monsters," Asimov shifted the focus of the genre toward the moral implications of human-robot interactions.123

These laws shaped discussions about robot ethics by providing a structured, albeit theoretical, set of rules that prioritize human safety:14

First Law: A robot may not injure a human being or, through inaction, allow a human being to come to harm.13
Second Law: A robot must obey human orders, provided they do not conflict with the First Law.13
Third Law: A robot must protect its own existence, provided it does not conflict with the First or Second Laws.13

While these laws have never been used to control real-world technology, they remain central to public and academic debates regarding artificial intelligence and the ethical challenges of autonomous systems. They serve as a vital thought experiment for considering how we might instill safety and accountability into increasingly autonomous machines.124
