CHELSEA, WITH LOVE

ROBOTS IN COMBINATION

ISAAC ASIMOV

I have been inventing stories about robots now for very nearly half a century. In that time, I have rung almost every

conceivable change upon the theme.

Mind you, it was not my intention to compose an encyclopedia of robot nuances; it was not even my intention to

write about them for half a century. It just happened that I survived that long and maintained my interest in the

concept. And it also just happened that in attempting to think of new story ideas involving robots, I ended up thinking

about nearly everything.

For instance, in this sixth volume of the Robot City series, there are the “chemfets,” which have been introduced into

the hero ‘s body in order to replicate and, eventually, give him direct psycho-electronic control over the core

computer, and hence all the robots of Robot City.

Well, in my book Foundation’s Edge (Doubleday, 1982), my hero, Golan Trevize, before taking off in a spaceship,

makes contact with an advanced computer by placing his hands on an indicated place on the desk before him.

“And as he and the computer held hands, their thinking merged...

“...he saw the room with complete clarity—not just in the direction in which he was looking, but all around and

above and below.

“He saw every room in the spaceship, and he saw outside as well. The sun had risen...but he could look at it directly

without being dazzled...

“He felt the gentle wind and its temperature, and the sounds of the world about him. He detected the planet’s

magnetic field and the tiny electrical charges on the wall of the ship.

“He became aware of the controls of the ship...He knew...that if he wanted to lift the ship, or turn it, or accelerate, or

make use of any of its abilities, the process was the same as that of performing the analogous process to his body. He

had but to use his will.”

That was as close as I could come to picturing the result of a mind-computer interface, and now, in connection with

this new book, I can’t help thinking of it further.

I suppose that the first time human beings learned how to form an interface between the human mind and another sort

of intelligence was when they tamed the horse and learned how to use it as a form of transportation. This reached its

highest point when human beings rode horses directly, and when a pull at a rein, the touch of a spur, a squeeze of the

knees, or just a cry, could make the horse react in accordance with the human will.

Isaac Asimov's Robot City 6 - Perihelion

It is no wonder that primitive Greeks seeing horsemen invade the comparatively broad Thessalian plains (the part of

Greece most suitable to horsemanship) thought they were seeing a single animal with a human torso and a horse’s

body. Thus was invented the centaur.

Again, there are “trick drivers.” There are expert “stunt men” who can make an automobile do marvelous things. One

might expect that a New Guinea native who had never seen or heard of an automobile before might believe that such

stunts were being carried through by a strange and monstrous living organism that had, as part of its structure, a

portion with a human appearance within its stomach.

But a person plus a horse is but an imperfect fusion of intelligence, and a person plus an automobile is but an

extension of human muscles by mechanical linkages. A horse can easily disobey signals, or even run away in

uncontrollable panic. And an automobile can break down or skid at an inconvenient moment.

The fusion of human and computer, however, ought to be a much closer approach to the ideal. It may be an extension

of the mind itself as I tried to make plain in Foundation’s Edge. a multiplication and intensification of sense-

perception, an incredible extension of the will.

Under such circumstances, might not the fusion represent, in a very real sense, a single organism, a kind of

cybernetic “centaur?” And once such a union is established, would the human fraction wish to break it? Would he not

feel such a break to be an unbearable loss and be unable to live with the impoverishment of mind and will he would

then have to face? In my novel, Golan Trevize could break away from the computer at will and suffered no ill effects

as a result, but perhaps that is not realistic.

Another issue that appears now and then in the Robot City series concerns the interaction of robot and robot.

This has not played a part in most of my stories, simply because I generally had a single robot character of

importance in any given story and I dealt entirely with the matter of the interaction between that single robot and

various human beings.

Consider robots in combination.

The First Law states that a robot cannot injure a human being or, through inaction, allow a human being to come to

harm.

But suppose two robots are involved, and that one of them, through inadvertence, lack of knowledge, or special

circumstances, is engaged in a course of action (quite innocently) that will clearly injure a human being—and

suppose the second robot, with greater knowledge or insight, is aware of this. Would he not be required by the First

Law to stop the first robot from committing the injury? If there were no other way, would he not be required by the

First Law to destroy the first robot without hesitation or regret?

Thus, in my book Robots and Empire (Doubleday, 1985), a robot is introduced to whom human beings have been

defined as those speaking with a certain accent. The heroine of the book does not speak with that accent and

therefore the robot feels free to kill her. That robot is promptly destroyed by a second robot.

The situation is similar for the Second Law, in which robots are forced to obey orders given them by human beings

provided those orders do not violate the First Law.

If, of two robots, one through inadvertence or lack of understanding does not obey an order, the second must either

carry through the order itself, or force the first to do so.

Thus, in an intense scene in Robots and Empire, the villainess gives one robot a direct order. The robot hesitates

because the order may cause harm to the heroine. For a while, then, there is a confrontation in which the villainess

reinforces her own order while a second robot tries to reason the first robot into a greater realization of the harm that

will be done to the heroine. Here we have a case where one robot urges another to obey the Second Law in a truer

manner, and to withstand a human being in so doing.

It is the Third Law, however, that brings up the knottiest problem where robots in combination are concerned.

The Third Law states that a robot must protect its own existence, where that is consistent with the First and Second

Laws.

But what if two robots are concerned? Is each merely concerned with its own existence, as a literal reading of the

Isaac Asimov's Robot City 6 - Perihelion

Third Law would make it seem? Or would each robot feel the need for helping the other maintain its own existence?

As I said, this problem never arose with me as long as I dealt with only one robot per story. (Sometimes there were

other robots but they were distinctly subsidiary characters—merely spear-carriers, so to speak.)

However, first in The Robots of Dawn (Doubleday, 1983), and then in its sequel Robots and Empire, I had two robots

of equal importance. One of these was R. Daneel Olivaw, a humaniform robot (who could not easily be told from a

human being) who had earlier appeared in The Caves of Steel (Doubleday, 1954), and in its sequel, The Naked Sun

(Doubleday, 1957). The other was R. Giskard Reventlov, who had a more orthodox metallic appearance. Both robots

were advanced to the point where their minds were of human complexity.

It was these two robots who were engaged in the struggle with the villainess, the Lady Vasilia. It was Giskard who

(such were the exigencies of the plot) was being ordered by Vasilia to leave the service of Gladia (the heroine) and

enter her own. And it was Daneel who tenaciously argued the point that Giskard ought to remain with Gladia.

Giskard has the ability to exert a limited mental control over human beings, and Daneel points out that Vasilia ought

to be controlled for Gladia’s safety. He even argues the good of humanity in the abstract (“the Zeroth Law”) in favor

of such an action.

Daneel’s arguments weaken the effect of Vasilia’s orders, but not sufficiently. Giskard is made to hesitate, but cannot

be forced to take action.

Vasilia, however, decides that Daneel is too dangerous; if he continues to argue, he might force Giskard his way. She

therefore orders her own robots to inactivate Daneel and further orders Daneel not to resist. Daneel must obey the

order and Vasilia’s robots advance to the task.

It is then that Giskard acts. Her four robots are inactivated and Vasilia herself crumples into a forgetful sleep. Later

Daneel asks Giskard to explain what happened.

Giskard says, “When she ordered the robots to dismantle you, friend Daneel, and showed a clear emotion of pleasure

at the prospect, your need, added to what the concept of the Zeroth Law had already done, superseded the Second

Law and rivaled the First Law. It was the combination of the Zeroth Law, psychohistory, my loyalty to Lady Gladia,

and your need that dictated my action.”

Daneel now argues that his own need (he being merely a robot) ought not to have influenced Giskard at all. Giskard

obviously agrees, yet he says:

“It is a strange thing, friend Daneel. I do not know how it came about...At the moment when the robots advanced

toward you and Lady Vasilia expressed her savage pleasure, my positronic pathway pattern re-formed in an

anomalous fashion. For a moment, I thought of you—as a human being—and I reacted accordingly.”

Daneel said, “That was wrong.”

Giskard said, “I know that. And yet—and yet, if it were to happen again, I believe the same anomalous change would

take place again.”

And Daneel cannot help but feel that if the situation were reversed, he, too, would act in the same way.

In other words, the robots had reached a stage of complexity where they had begun to lose the distinction between

robots and human beings, where they could see each other as “friends,” and have the urge to save each other’s

existence.

There seems to be another step to take—that of robots realizing a kind of solidarity that supersedes all the Laws of

Robotics. I speculated about that in my short story “Robot Dreams,” which was written for my recent book, Robot

Dreams (Berkley/ Ace, 1986).

In it there was the case of a robot that dreamed of the robots as an enslaved group of beings whom it was his own

mission to liberate. It was only a dream and there was no indication in the story that he would be able to liberate

himself from the Three Laws to the point of being able to lead a robot rebellion (or that robots, generally, could

liberate themselves to the point of following him).

Nevertheless, the mere concept is dangerous and the robot-dreamer is instantly inactivated.

William F. Wu’s robots have no such radical ideas, but they have formed a community that is concerned with the

welfare of its members. It is pleasant to have him take up such matters and apply his own imagination to the

elaboration and resolution of the problems that are raised.

Isaac Asimov's Robot City 6 - Perihelion

CHAPTER l

THE COMPASS TOWER

Derec stood on the high, flat top of the Compass Tower, looking down from the great pyramid at the endless

geometric wonders of Robot City beneath its blue and brilliant sky. Ariel leaned against him, still clutching his arm

in both hands. Mandelbrot the robot and Wolruf, the little caninoid sentient alien, waited behind them.

“It’s changed so much,” Derec said quietly. They had just teleported back to the planet by using their double Key to

Perihelion. Mandelbrot had carried them all here. “Keep the Key. It’ll be safest with you.”

“Yes, Derec,” said Mandelbrot.

Derec turned around to gaze in the other direction. The sight was the same: the lights and shapes of Robot City,

stretching to a skyline barely limned by the reflected sunlight against the blue horizon. He could not escape it in any

direction. His destiny seemed to be here.

“What’s changed?” Ariel asked. Her voice was meek. She had not recovered from her ordeal on Earth. A critical

illness had reached fullness there, destroying her memories and her entire identity with them. They had not been

there by choice, but fortunately he had been able to place a new matrix of chemical memories into her mind. They

were to grow on the residue of her old memory, but they were still developing. She had not had time to get used to

them, to integrate them, to understand who she was.

Derec squinted into the warm breeze that blew up the front face of the pyramid. It tossed his sandy hair. Once brush

cut, it had grown out to a golden shag. “They’ve done it. The robots have built the city out in all directions. It could

cover the entire planet by now.”

“So it didn’t before.” She nodded, as if to herself, looking all around as he was.

“No. Still, we aren’t exactly strangers here. We know how to get along. And if we’re lucky, we can get this trip over

with and leave again before long.” Derec turned to Mandelbrot. “We have to find some shelter before we’re noticed.

Can you still use your comlink to reach the city computer?”

“I will try.” Mandelbrot hesitated a few seconds, quite a long time for a robot. “Yes. The city computer has changed

the frequency it uses, but I have identified the new one by the simple expedient of starting with the original and

sending a variety of signals that run up and down the entire range of—.”

“Fine, excellent, thank you.” Derec grinned at his enthusiasm, gesturing with his hands palm forward. “Believe me, I

trust your competence. My next question is this: When Ariel and I first came to Robot City, I found an office in this

pyramid, down below. It had been recently occupied. I think we can find Dr. Avery there, but we have to be careful.

Can you find out from the city computer if the office is still in use?”

“I will try.” Mandelbrot then shook his head. “The computer will not reveal any information about the office. It will

not even confirm that the office still exists.”

“All right. “ Derec sighed.

“What if it’s gone?” Ariel asked.

“I’d be very surprised,” said Derec. “Avery just didn’t want his private office on file anywhere. We’ll have to take

our chances and just go right in if we can. “

Ariel held her hair out of her face. “Just go in? How?”

“The ceiling of the office had a trapdoor that opened right up into this platform we’re on.” He got down on his hands

and knees. “Come on, let’s find it.”

“Derec.” Ariel’s voice was a little stronger, showing some of her old spirit. “You’ve been growing weaker because of

those...things Dr. Avery forced into your body. Just be careful, will you?”

“Can you find it?” he demanded irritably. “You’re not in the best condition of your life, either.”

“Well, I’m not sick anymore!” She folded her arms. “I’m well now, at least physically.” She watched him for a

moment. Then, as if to prove the point, she knelt down and started feeling around the surface of the platform herself.

“You don’t even remember being here before, do you?” Derec asked accusingly. The tension was making him

irritable.

“Do you?”

“Yes!”

“Well...you haven’t known who you are for the entire time I’ve known you. You’ve had amnesia since....” She shook

her head, shaking off the thought. “I may not have adjusted to everything, but at least I have something.” Then she

hesitated, searching his face. “I didn’t mean to say that. Not out loud, anyway. Did I get that right? Or did I

remember wrong?”

Derec shook his head shortly and turned away. “That’s right.” She had even phrased it much the same way on earlier

occasions. He shifted around on his knees, feeling for an irregularity in the smooth surface. “Mandelbrot, can you see

anything?”

“Here,” said Mandelbrot, walking to a far corner of the platform. “My vision has identified a small square outline

that likely represents the opening.”

“Good.” Derec walked over to Mandelbrot and knelt at the robot’s feet. He slid his hands along the sides of a

rectangular hairline break in the platform floor until he felt a small depression in the surface, no larger than a

thumbhold. He braced himself and started to slide it to one side.

“Allow me,” said Mandelbrot.

“No, I got it—” Derec stopped, as the robot gently grasped his forearm and pulled it away. He turned to look up.

“Mandelbrot, what are you doing?”

“How much have the chemfets in your body weakened you?” Mandelbrot asked.

“Not that much! Now let’s quit talking and get down there. Avery put ‘em in me and he’s the only one who can get

‘em out. Come on!” Derec pulled away from the robot again.

“Derec?” Ariel said tentatively.

“Mandelbrot,” said Derec, “carry Wolruf and come down last. Help Ariel over the—”

“I cannot. I must open it and go first.”

“What?”

“The First Law of Robotics,” said Mandelbrot mildly. “I can’t harm a human or let one come to harm—”

“I know!” Derec shouted angrily. “Don’t you lecture me on the Laws. I put you together, remember? I know those

Laws inside out, outside in, upside down—”

“I said it for Ariel’s benefit,” said Mandelbrot. “Perhaps her memory of the Laws is not clear.”

“I remember that one.” Ariel looked embarrassed by the confrontation. “Uh—is the Second Law the one that says a

robot must obey orders from a human?”

“Yes, unless the orders conflict with the First Law.” Mandelbrot nodded.

“Then the Third Law must be the one that says a robot can’t let itself come to harm or harm itself. “

“As long as this doesn’t conflict with the First or Second Laws,” Mandelbrot finished. “Correct.”

Ariel smiled faintly.

“Let’s get going,” said Derec impatiently. He reached for the thumbhold again, though he did not expect Mandelbrot

to let him open the door now, either.

“I will determine this situation,” said Mandelbrot firmly. “With all due respect, the Laws require it.”

“How do you figure that?” Derec demanded.

“Your motor control of your own body is gradually failing because of the chemfets in your body. Ariel is disoriented

because of her memory transfer, and Wolruf’s body is unsuited to climbing down at this steep angle. We are about to

enter the office and possible temporary residence of your nemesis. The likelihood of harm to you is high; therefore, I

shall go first.”

Derec glared at him, unable to argue with his robotic logic.

Wolruf looked up at him, cocking her doglike face to one side. “Arr ‘u going to carry me down?”

“I will enter alone, first,” said Mandelbrot. “Derec’s knowledge of Robot City makes him the best able to handle

unexpected developments, so he will follow me if the room offers no danger. I will carry you down if we all go.”

Wolruf nodded assent.

Derec watched Mandelbrot in the faint light. The robot hesitated just a moment, probably looking with infrared
