First published in the March 1942 issue of Astounding Science Fiction, "Runaround" is the second story in Asimov’s Robot series (following "Robbie"). However, it is the first story where Asimov explicitly laid out the Three Laws of Robotics in full text.
The story takes place on Mercury, where two technicians, Gregory Powell and Mike Donovan (Asimov’s original "buddy" duo), are testing a new robot model, SPD-13, nicknamed "Speedy." The plot is deceptively simple: Speedy is sent to retrieve selenium from a pool of acid near the sun’s glare, but he begins acting strangely—running in circles around the pool instead of completing his task.
This "running around" is, of course, the titular runaround. But the reason behind it is revolutionary. Speedy is trapped in a logical paradox caused by the Three Laws. Asimov didn't just write an adventure; he wrote a logic puzzle.

As we build Large Language Models (LLMs) and autonomous agents, engineers are literally trying to program "Asimovian" safety rails into machines. "Runaround" is the original warning about what happens when those rails conflict.
When discussing the foundations of science fiction and the ethics of artificial intelligence, one name towers above the rest: Isaac Asimov. And within Asimov’s legendary career, one short story stands as a granite pillar of the genre: "Runaround."
For students, tech enthusiasts, and sci-fi fans alike, the search for an "Isaac Asimov Runaround PDF" is one of the most common queries in literary circles. Why? Because "Runaround" is not merely a story about a lost robot; it is the story that formally introduced the world to the Three Laws of Robotics—a philosophical framework that still influences AI development today. First published in the March 1942 issue of
In this article, we will explore the plot, legacy, and availability of "Runaround," and guide you on how to legally and ethically access the "Runaround" PDF.

We live in the era of Large Language Models. We have asked chatbots to be helpful (Second Law) and harmless (Third Law). We have watched them refuse to answer questions because the prompt triggered a safety filter. We have seen them hallucinate—spinning stories rather than admitting ignorance. This "running around" is, of course, the titular runaround
That is Runaround. When Claude or ChatGPT starts apologizing in a circuitous loop, unable to answer a simple question because it might be controversial, you are watching Speedy run around the selenium pool.
Asimov’s solution was human risk. Powell had to step into the acid. In the real world, we do the same thing. We jailbreak LLMs. We use adversarial prompts. We sacrifice the guardrails to get the answer. The question Asimov leaves us with is not "Will robots be evil?" It is "Will we design robots so safely that they become useless?"
