The Three Laws of Robotics are a set of rules created by science-fiction writer Isaac Asimov, which first appeared in his 1942 short story Runaround. These laws were designed to prevent robots from harming humans and to drive the plots of his fictional stories. The laws have since been modified by Asimov and other authors and have become hugely influential in the sci-fi genre, as well as in discussions involving technology, robotics, and AI. The three laws are as follows:
1. A robot may not injure a human or, through inaction, allow a human to come to harm.
2. A robot must obey orders given to it by humans, except when 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.

What You'll Learn
- Isaac Asimov created the three laws of robotics
- The laws were created to drive the plots of his fictional stories

Isaac Asimov created the three laws of robotics
The Three Laws of Robotics are as follows:
- A robot may not injure a human or, through inaction, allow a human to come to harm.
- A robot must obey orders given to it by humans, except when 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.
Asimov wrote these laws with intentional ambiguity, creating loopholes that challenged his characters and readers with ethical dilemmas. The laws are written in English, a natural language with inherent ambiguity, which makes it difficult to code the laws into precise, machine-readable instructions. Despite their influence, the laws are not without criticism. Some have pointed out that the laws are deeply flawed and that Asimov's stories highlight how robots can still make mistakes and exhibit unpredictable behaviour when following these rules.
Over time, Asimov made slight modifications to the first three laws in his subsequent works to further develop how robots would interact with humans and each other. In later fiction, he introduced a fourth or "Zeroth" Law that took precedence over the previous three: "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 for the greater good.

The laws were created to drive the plots of his fictional stories
Isaac Asimov created the Three Laws of Robotics to drive the plots of his fictional stories. The laws were designed to prevent robots from harming humans and to expose how robots' behaviour can be unpredictable, even when following these rules.
The first mention of the laws was in Asimov's short story "Runaround", published in 1942, and they subsequently became hugely influential in the sci-fi genre. The laws are as follows:
- A robot may not injure a human or, through inaction, allow a human to come to harm.
- A robot must obey orders given to it by a human, except when 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.
Asimov wrote the laws with intentional ambiguity, creating loopholes that challenged his characters and readers with ethical dilemmas. The laws are written in English, a natural language with inherent ambiguity, which makes it difficult to code the laws into precise, machine-readable instructions. This is exemplified in "Evidence", where a character reasons that an individual obeying the Three Laws may be a robot or simply "a very good man".
In later fiction, Asimov added a fourth, or "Zeroth" Law, which takes precedence over the other three:
A robot may not harm humanity, or, by inaction, allow humanity to come to harm.
This law enforces decision-making robots to prioritise humanity as a whole over a single individual for the greater good.

The laws are: a robot must not harm a human, must obey orders, and must protect its existence
The Three Laws of Robotics were created by science-fiction writer Isaac Asimov. They were introduced in his 1942 short story "Runaround", although he had previously written two robot stories with no explicit mention of the laws. The laws were designed to prevent robots from harming humans and to drive the plots of his fictional stories.
The three laws are as follows:
- A robot may not injure a human or, through inaction, allow a human to come to harm.
- A robot must obey the orders given to it by humans, except when 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 have also impacted discussions involving technology, robotics, and AI. However, it is important to note that Asimov wrote the laws with intentional ambiguity to create ethical dilemmas in his stories. The laws are written in English, which is inherently ambiguous, and this makes it challenging to code them into precise, machine-readable instructions.
Asimov himself modified the laws in subsequent works to further explore the interactions between robots and humans. He also introduced a fourth, or "Zeroth Law", in later fiction: "A robot may not harm humanity, or, by inaction, allow humanity to come to harm." This law takes precedence over the other three and allows a robot to override human commands if it can calculate long-term harm.

The laws have been modified and built upon by Asimov and other authors
The Three Laws of Robotics have been modified and built upon by Asimov and other authors. Asimov himself made slight modifications to the first three laws in subsequent works to further develop how robots would interact with humans and each other. In later fiction where robots had taken responsibility for governing whole planets and human civilizations, Asimov added a fourth, or "zeroth" law, to precede the others. The Zeroth Law states that "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.
In his story "Little Lost Robot," Asimov created a variation of the First Law to address a practical difficulty that robots face when working alongside human beings who are exposed to low doses of radiation. The robots in the story are rendered inoperable by doses that are reasonably safe for humans, and they are destroyed while attempting to rescue the humans. Asimov also introduced the concept of a "robopsychologist" in his stories, a professional who specializes in understanding and treating robot mental health and the psychological implications of the Three Laws.
Other authors have also created extra laws of robotics. In the 1974 novel Icarus's Way, Lyuben Dilov introduced a Fourth Law of robotics: "A robot must establish its identity as a robot in all cases." In 2013, Hutan Ashrafian proposed an additional law, the AIonAI law, which considers the relationship between artificial intelligence systems. In 2024, Dariusz Jemielniak proposed another Fourth Law: "A robot or AI must not deceive a human by impersonating a human being."

The laws have influenced thought on the ethics of artificial intelligence
The Three Laws of Robotics were created by science fiction writer Isaac Asimov. They were introduced in his 1942 short story "Runaround" and subsequently became hugely influential in the sci-fi genre and discussions involving technology, robotics, and AI. The laws are as follows:
- A robot may not injure a human or, through inaction, allow a human to come to harm.
- A robot must obey orders given to it by humans, except when 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 also prompted exploration into the potential loopholes and ethical dilemmas that may arise. For instance, a scenario where a robot must break one law to fulfil another, or where the interpretation of "harm" is ambiguous and subject to multiple interpretations. This has resulted in proposals for additional laws, such as the Zeroth Law, which states that "a robot may not harm humanity, or by inaction, allow humanity to come to harm", taking precedence over the original three laws.
Furthermore, the Three Laws of Robotics have inspired authors and scholars to create and discuss additional laws that address specific aspects of AI behaviour. For example, the Fourth Law proposed by Lyuben Dilov in his 1974 novel "Icarus' Way" addresses the ethical implications of robots being designed to resemble humans. In 2013, Hutan Ashrafian proposed the AIonAI law, which considers the relationship between artificial intelligence systems themselves. These discussions and proposals influenced and expanded the ethical considerations surrounding AI and robotics, demonstrating the impact of Asimov's original Three Laws.
