Science fiction author Isaac Asimov first introduced the Three Laws of Robotics in his 1942 short story Runaround. The laws, which were to be followed by robots in several of his stories, are: A robot may not injure a human being or, through inaction, allow a human being to come to harm; a robot must obey the orders given it by human beings except where such orders would conflict with the first law; and a robot must protect its own existence as long as such protection does not conflict with the first or second law. Asimov later added a fourth or zeroth law that superseded the others: A robot may not harm humanity, or, by inaction, allow humanity to come to harm.

Isaac Asimov first wrote about the three laws of robotics
Isaac Asimov, a science fiction author, first wrote about the Three Laws of Robotics. These laws were introduced in his 1942 short story "Runaround", which was included in the 1950 collection "I, Robot". The laws are as follows:
> A robot may not injure a human being or, through inaction, allow a human being to come to harm.
> A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
> A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
These laws were presented as being from the fictional "Handbook of Robotics, 56th Edition, 2058 A.D." and form an organising principle and unifying theme for Asimov's robot-based fiction. They appear in his Robot series and the stories linked to it.
Asimov is widely credited with the invention of the term "robotics" and is considered one of the "Big Three" science fiction writers, alongside Robert Heinlein and Arthur Clarke.
The Three Laws of Robotics have become hugely influential in the sci-fi genre and have also found relevance in discussions involving technology, including robotics and AI. They were designed to be an ethical system for humans and robots, with Asimov seeking to counter the popular Frankensteinian trope, in which a creation destroys its maker.
Despite their influence, Asimov's laws have been criticised as being flawed and unfit for real-world application. Some have pointed out that the laws are fictional and were intended as plot devices by Asimov, who wrote them with intentional ambiguity to create ethical dilemmas for his characters. Others have noted the inherent challenge of programming machines to think and act like humans, as the laws assume.
Asimov himself later added a fourth or "Zeroth Law" that superseded the others:
> A robot may not harm humanity, or, by inaction, allow humanity to come to harm.

The laws were introduced in his 1942 short story Runaround
The Three Laws of Robotics were first introduced by science fiction author Isaac Asimov in his 1942 short story "Runaround". The laws are as follows:
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
These laws were presented as being from the fictional "Handbook of Robotics, 56th Edition, 2058 A.D." and were intended to be followed by robots in several of Asimov's stories. They form an organizing principle and unifying theme for his robot-based fiction, appearing in his Robot series and the stories linked to it.
The laws have since been influential in both the sci-fi genre and discussions involving technology, robotics, and AI. They have shaped ethical discussions around artificial intelligence and contributed to real-world frameworks and safety policies. Other authors have also adopted and elaborated on the laws, and Asimov himself made slight modifications to them in subsequent works to further develop how robots would interact with humans and each other.
However, some critics argue that the laws are flawed and unsuitable for real-world application. They were written with intentional ambiguity, leading to multiple interpretations and ethical dilemmas. Additionally, the laws assume that robots will think and interpret them like humans, which is not yet possible in practice. Despite these criticisms, Asimov's Three Laws of Robotics remain a significant contribution to the world of robotics and artificial intelligence.

The laws are a set of rules to be followed by robots in Asimov's stories
The Three Laws of Robotics, often shortened to The Three Laws or Asimov's Laws, are a set of rules created by science fiction author Isaac Asimov. These laws were to be followed by robots in several of his stories and were introduced in his 1942 short story "Runaround" (included in the 1950 collection I, Robot).
The Three Laws, presented as an extract from the fictional "Handbook of Robotics, 56th Edition, 2058 A.D.", are as follows:
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
These laws form an organising principle and unifying theme for Asimov's robot-based fiction, appearing in his Robot series and the stories linked to it. They are incorporated into almost all of the positronic robots appearing in his fiction and are intended as a safety feature.
A number of Asimov's robot-focused stories involve robots behaving in unusual and counter-intuitive ways as an unintended consequence of how the robot applies the Three Laws to its situation. The laws are written with intentional ambiguity, creating loopholes that challenge the characters and audience with ethical dilemmas. Asimov himself wrote that he should not be praised for creating the Laws, as they are "obvious".
In later fiction, where robots had taken responsibility for governing whole planets and human civilizations, Asimov added a fourth or "Zeroth Law" that superseded the others: "A robot may not harm humanity, or, by inaction, allow humanity to come to harm." This law enforces decision-making robots to prioritize humanity as a whole over a single individual in the interest of the greater good.

The laws are: a robot may not injure a human, a robot must obey orders, a robot must protect its existence
The Three Laws of Robotics, often shortened to The Three Laws or Asimov's Laws, were first introduced by science fiction author Isaac Asimov in his 1942 short story "Runaround". The laws are as follows:
First Law
"A robot may not injure a human being or, through inaction, allow a human being to come to harm." This is similar to the expectation that human beings refrain from harming other human beings, except in extreme situations such as war or to save a greater number.
Second Law
"A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law." This is comparable to the expectation that individuals obey instructions from recognized authorities, such as doctors or teachers.
Third Law
"A robot must protect its own existence as long as such protection does not conflict with the First or Second Law." This reflects the human instinct for self-preservation and the desire to avoid self-harm.
These laws were intended by Asimov to create an ethical system for humans and robots, and they became a unifying theme in his robot-based fiction. They have also influenced discussions about technology, robotics, and AI, and have even shaped safety policies at companies like Google. However, critics argue that these laws are flawed and were never meant to be applied in the real world, serving only as plot devices in Asimov's stories.

The laws have been influential in sci-fi and discussions on technology and AI
The Three Laws of Robotics were first introduced by science fiction author Isaac Asimov in his 1942 short story "Runaround". The laws, which were to be followed by robots in several of his stories, are:
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
The laws have been influential in the sci-fi genre and in discussions on technology and AI. Asimov's laws have been referenced and altered in numerous science fiction works, with some authors adopting them when working in Asimov's fictional universe. The laws have also sparked discussions on the role of responsibility and authority when designing robotic platforms and the larger systems in which they operate. For example, Robin Murphy and David D. Woods proposed "The Three Laws of Responsible Robotics" to stimulate discussion on these topics.
Additionally, Asimov's laws have been influential in considering the potential benefits and dangers of artificial intelligence. The notion of machines with human-like intelligence has been a recurring theme in science fiction, with some works exploring the idea of government by algorithm or AI-controlled societies. Asimov's laws have contributed to these discussions by presenting a potential ethical system for humans and robots to coexist.
However, some critics have pointed out that Asimov's laws are not without their flaws. The laws assume that machines will think and interpret rules like humans, which may not be the case. Furthermore, Asimov's own stories often highlight the limitations of the laws, with scenarios in which the rules can be worked around or do not work as planned. Despite this, the laws continue to capture the public imagination and influence the way people think about robotics and AI.
