Three Laws of Robotics
A set of rules governing the behavior of robots.
Three Laws of Robotics: Asimov's fictional framework, not industry standard
The Three Laws of Robotics are a fictional ethical framework published by science fiction author Isaac Asimov, beginning with his 1942 short story "Runaround." They are not an engineering standard, industry specification, or binding principle in robotics development. The laws exist only in Asimov's narrative universe and have no technical implementation in real robotic systems.
The three laws, as Asimov defined them, 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. In Asimov's stories, these rules were encoded into the positronic brains of his robots as unbreakable logical constraints.
Why they matter in practice
The Three Laws have become culturally dominant in how non-specialists imagine robot behavior and safety. They appear frequently in popular discussion, policy debates, and educational contexts about artificial intelligence and autonomous systems. However, this cultural presence can obscure actual engineering reality: safety in real robotics depends on hardware limits, software architecture, fail-safes, operational constraints, and regulatory compliance, not on a universal ethical law embedded in the machine.
Real industrial and collaborative robots operate under strict safety standards such as ISO/TS 15066 for collaborative robots and ISO 10218 for industrial robot safety. These standards specify mechanical brakes, force-limiting algorithms, speed restrictions, and operator isolation, rather than ethical rules. The gap between Asimov's fictional framework and engineering practice remains vast.
The term is useful chiefly as a cultural touchstone when discussing public perception of robotics, AI governance, or the philosophical dimensions of autonomous machines. In technical contexts, referencing the Three Laws can signal unfamiliarity with how real robotic safety is engineered and regulated.
