MY ROBOTS
by ISAAC ASIMOV
I wrote my first robot story, “Robbie,” in May of 1939, when I was only nineteen years old.
What made it different from robot stories that had been written earlier was that I was determined not
to make my robots symbols. They were not to be symbols of humanity’s over-weening arrogance. They
were not to be examples of human ambitions trespassing on the domain of the Almighty. They were not to
be a new Tower of Babel requiring punishment.
Nor were the robots to be symbols of minority groups. They were not to be pathetic creatures that
were unfairly persecuted so that I could make Aesopic statements about Jews, Blacks or any other
mistreated members of society. Naturally, I was bitterly opposed to such mistreatment and I made that
plain in numerous stories and essays—but not in my robot stories.
In that case, what did I make my robots?—I made them engineering devices. I made them tools. I
made them machines to serve human ends. And I made them objects with built-in safety features. In
other words, I set it up so that a robot could not kill his creator, and having outlawed that heavily
overused plot, I was free to consider other, more rational consequences.
Since I began writing my robot stories in 1939, I did not mention computerization in their
connection. The electronic computer had not yet been invented and I did not foresee it. I did foresee,
however, that the brain had to be electronic in some fashion. However, “electronic” didn’t seem futuristic
enough. The positron—a subatomic particle exactly like the electron but of opposite electric
charge—had been discovered only four years before I wrote my first robot story. It sounded very
science fictional indeed, so I gave my robots “positronic brains” and imagined their thoughts to consist of
flashing streams of positrons, coming into existence, then going out of existence almost immediately.
These stories that I wrote were therefore called “the positronic robot series,” but there was no greater
significance than what I have just described to the use of positrons rather than electrons.
At first, I did not bother actually systematizing, or putting into words, just what the safeguards were
that I imagined to be built into my robots. From the very start, though, since I wasn’t going to have it
 
possible for a robot to kill its creator, I had to stress that robots could not harm human beings; that this
was an ingrained part of the makeup of their positronic brains.
Thus, in the very first printed version of “Robbie” (it appeared in the September 1940 Super Science
Stories , under the title of “Strange Playfellow”), I had a character refer to a robot as follows: “He just
can’t help being faithful and loving and kind. He’s a machine, made so .”
After writing “Robbie,” which John Campbell, of Astounding Science Fiction , rejected, I went on
to other robot stories which Campbell accepted. On December 23, 1940, I came to him with an idea for
a mind-reading robot (which later became “Liar!”) and John was dissatisfied with my explanations of why
the robot behaved as it did. He wanted the safeguard specified precisely so that we could understand the
robot. Together, then, we worked out what came to be known as the “Three Laws of Robotics.” The
concept was mine, for it was obtained out of the stories I had already written, but the actual wording (if I
remember correctly) was beaten out then and there by the two of us.
The Three Laws were logical and made sense. To begin with, there was the question of safety,
which had been foremost in my mind when I began to write stories about my robots. What’s more I was
aware of the fact that even without actively attempting to do harm, one could quietly, by doing nothing,
allow harm to come. What was in my mind was Arthur Hugh Clough’s cynical “The Latest Decalog,” in
which the Ten Commandments are rewritten in deeply satirical Machiavellian fashion. The one item most
frequently quoted is: “Thou shalt not kill, but needst not strive/Officiously to keep alive.”
For that reason I insisted that the First Law (safety) had to be in two parts and it came out this way:
1. A robot may not injure a human being, or, through inaction, allow a human being to come to
harm.
Having got that out of the way, we had to pass on to the second law (service). Naturally, in giving
the robot the built-in necessity to follow orders, you couldn’t forfeit the overall concern of safety. The
second law had to read as follows, then:
2. A robot must obey the orders given it by human beings except where such orders would conflict
with the First Law.
And finally, we had to have a third law (prudence). A robot was bound to be an expensive machine
and it must not needlessly be damaged or destroyed. Naturally, this must not be used as a way of
compromising either safety or service. The Third Law, therefore, had to read as follows:
3. A robot must protect its own existence, as long as such protection does not conflict with the First
or Second Laws.
Of course, these laws are expressed in words, which is an imperfection. In the positronic brain, they
are competing positronic potentials that are best expressed in terms of advanced mathematics (which is
well beyond my ken, I assure you). However, even so, there are clear ambiguities. What constitutes
“harm” to a human being? Must a robot obey orders given it by a child, by a madman, by a malevolent
human being? Must a robot give up its own expensive and useful existence to prevent a trivial harm to an
unimportant human being? What is trivial and what is unimportant?
These ambiguities are not shortcomings as far as a writer is concerned. If the Three Laws were
perfect and unambiguous there would be no room for stories. It is in the nooks and crannies of the
ambiguities that all one’s plots can lodge, and which provide a foundation, if you’ll excuse the pun, for
Robot City .
I did not specifically state the Three Laws in words in “Liar!” which appeared in the May 1941
Astounding . I did do so, however, in my next robot story, “Runaround,” which appeared in the March
1942 Astounding . In that issue on line seven of page one hundred, I have a character say, “Now, look,
let’s start with the three fundamental Rules of Robotics,” and I then quote them. That, incidentally, as far
as I or anyone else has been able to tell, represents the first appearance in print of the word
“robotics”—which, apparently, I invented.
Since then, I have never had occasion, over a period of over forty years during which I wrote many
stories and novels dealing with robots, to be forced to modify the Three Laws. However, as time passed,
and as my robots advanced in complexity and versatility, I did feel that they would have to reach for
something still higher. Thus, in Robots and Empire , a novel published by Doubleday in 1985, I talked
 
about the possibility that a sufficiently advanced robot might feel it necessary to consider the prevention
of harm to humanity generally as taking precedence over the prevention of harm to an individual. This I
called the “Zeroth Law of Robotics,” but I’m still working on that.
My invention of the Three Laws of Robotics is probably my most important contribution to science
fiction. They are widely quoted outside the field, and no history of robotics could possibly be complete
without mention of the Three Laws. In 1985, John Wiley and Sons published a huge tome, Handbook of
Industrial Robotics , edited by Shimon Y. Nof, and, at the editor’s request, I wrote an introduction
concerning the Three Laws.
Now it is understood that science fiction writers generally have created a pool of ideas that form a
common stock into which all writers can dip. For that reason, I have never objected to other writers who
have used robots that obey the Three Laws. I have, rather, been flattered and, honestly, modern science
fictional robots can scarcely appear without those Laws.
However, I have firmly resisted the actual quotation of the Three Laws by any other writer. Take the
Laws for granted, is my attitude in this matter, but don’t recite them. The concepts are everyone’s but the
words are mine.
But, then, I am growing old. I cannot expect to live for very much longer, but I hope that some of
my brainchildren can. And to help those brainchildren attain something approaching long life, it is just as
well if I relax my rules and allow others to make use of them and reinvigorate them. After all, much has
happened in science since my first robot stories were published four decades ago, and this has to be
taken into consideration, too.
Therefore, when Byron Preiss came to me with the notion of setting up a series of novels under the
overall title of Robot City , in which “Asimovian” robots and ideas were to be freely used, I felt drawn to
the notion. Byron said that I would serve as a consultant to make sure that my robots stay “Asimovian,”
that I would answer questions, make suggestions, veto infelicities, and provide the basic premise for the
series as well as challenges for the authors. (And so it was done. Byron and I sat through a series of
breakfasts in which he asked questions and I—and sometimes my wife, Janet, as well—answered, thus
initiating some rather interesting discussions.)
Furthermore, my name was to be used in the title so as to insure the fact that readers would know
that the project was developed in conjunction with me, and was carried through with my help and
knowledge. It is, indeed, a pleasure to have talented young writers devote their intelligence and ingenuity
to the further development of my ideas, doing so each in his or her own way.
The first novel of the series, Robot City Book 1: Odyssey , is by Michael P. Kube-McDowell, the
author of Emprise , and I am very pleased to be connected with it. The prose is entirely Michael’s; I did
none of it. In saying this, I am not trying to disown the novel at all; rather I want to make sure that
Michael gets all the credit from those who like the writing. It is my role, as I have indicated, only to
supply robotic concepts, answer (as best I can) questions posed by Byron and Michael, and suggest
solutions to problems raised by the Three Laws. In fact, Book Two of this series will introduce three
interesting new laws concerning the way robots would deal with humans in a robotic society, a
relationship which is the underpinning of Robot City .
In nearly half a century of writing I have built up a name that is well known and carries weight and I
would like to use it to help pave the way for young writers by way of their novels and to preserve the
names of older writers by the editing of anthologies. The science fiction field in general and a number of
science fiction practitioners in particular have, after all, been very good to me over the years, and the best
repayment I can make is to do for others what it and they have done for me.
Let me emphasize that this is the first time I have allowed others to enter my world of robots and to
roam about freely there. I am pleased with what I’ve seen so far, including the captivating artwork of
Paul Rivoche, and I look forward to seeing what is done with my ideas and the concepts I have
proposed in the books that follow. The books may not be (indeed, are bound not to be) exactly as I
would have written them, but all the better. We’ll have other minds and other personalities at work,
broadening, raising, and refocusing my ideas.
For you, the reader, the adventure is about to begin.
 
CHAPTER 1
AWAKENING
The youth strapped in the shock couch at the center of the small chamber appeared to be peacefully
sleeping. The muscles of his narrow face were relaxed, and his eyes were closed. His head had rolled
forward until his chin rested on the burnished metal neck ring of his orange safesuit. With his smooth
cheeks and brush-cut sandy blond hair, he looked even younger than he was—young enough to raise the
doorman’s eyebrow at the least law-abiding spaceport bar.
He came to consciousness slowly, as though he had been cheated of sleep and was reluctant to give
it up. But as the fog cleared, he had a sudden, terrifying sensation of leaning out over the edge of a cliff.
His eyes flashed open, and he found himself looking down. The couch into which the five-point
harness held him was tipped forward. Without the harness, he would have awakened in a jumbled heap
on the tiny patch of sloping floor plate, wedged against the one-ply hatch that faced him.
He raised his head, and his darting eyes quickly took in the rest of his surroundings. There was little
to see. He was alone in the tiny chamber. If he unstrapped himself, there would be room for him to stand
up, perhaps to turn around, but nothing more ambitious. A safesuit helmet was cached in a recess on the
curving right bulkhead. On the left bulkhead was a dispensary, with its water tube and delivery chute.
None of what he saw made sense, so he simply continued to catalog it. Above his head, hanging
from the ceiling, was some sort of command board with a bank of eight square green lamps labeled “P1,”
“P2,” “F,” and the like. The board was in easy reach, except that there appeared to be no switches or
controls for him to manipulate. In one corner of the panel the word MASSEY was etched in stylized
black letters.
Apart from the slight rasp of his own breathing, the little room was nearly silent. From the machinery
which filled the space behind his shoulders and under his feet came the whir of an impeller and a faint
electric hum. But there was no sound from outside, from beyond the walls.
Thin as it was, the catalog was complete, and it was time to try to make something of it. He realized
that, although he did not recognize his surroundings, he was not surprised by them. But then, since he
could not remember where he had fallen asleep, he had carried no expectations about where he should
be when he awoke.
The simple truth was he did not know where he was. Or why he was there. He did not know how
long he had been there, or how he had gotten there.
But at the moment none of those things seemed to matter, for he realized—with rapidly growing
dismay and disquiet—that he also did not know who he was.
He searched his mind for any hint of his identity—of a place he had known, of a face that was
important to him, of a memory that he treasured. There was nothing. It was as though he was trying to
read a blank piece of paper. He could not remember a single event which had taken place before he had
opened his eyes and found himself here. It was as though his life had begun at that moment.
Except he knew that it had not. He was nota crying newborn child, but a man—or near enough to
one to claim the title until challenged. He had existed. He had had an identity and a place in the world. He
had had friends—parents—a home. He had to have had all of that and more.
But it was gone.
It was a different feeling than merely forgetting. At least when you forget something, you have a
sense that you once knew it—
“Are you all right?” a pleasant voice inquired, breaking the silence and making him suddenly tense all
his muscles.
“Who are you?” he demanded. “Where are you? Where am I?”
“I am Darla, your Companion. Please try to remain calm. We’re in no immediate danger.” The
voice, coming from the command panel before him, was more clearly female now. “You are inside a
