The Rest of the Robots

by Isaac Asimov

  Lanning missed the gentle jab. He said, 'I ought to be used to it, but I never will. You'd think that by now every human being on Earth would know that the Three Laws represented a perfect safeguard; that robots are simply not dangerous. Take this bunch.' He glowered down. 'Look at them. Most of them go through the robot assembly room for the thrill of fear, like riding a roller coaster. Then when they enter the room with the MEC model—damn it, Peter, a MEC model that will do nothing on God's green Earth but take two steps forward, say "Pleased to meet you, sir," shake hands, then take two steps back—they back away and mothers snatch up their kids. How do we expect to get brainwork out of such idiots?' '

  Bogert had no answer. Together, they stared down once again at the line of sightseers, now passing out of the computer room and into the positronic brain assembly section. Then they left. They did not, as it turned out, observe Mortimer W. Jacobson, age 16—who, to do him complete justice, meant no harm whatever.

  In fact, it could not even be said to be Mortimer's fault. The day of the week on which the tour took place was known to all workers. All devices in its path ought to have been carefully neutralized or locked, since it was unreason­able to expect human beings to withstand the temptation to handle knobs, keys, handles, and pushbuttons. In addition, the guide ought to have been very carefully on the watch for those who succumbed.

  But, at the time, the guide had passed into the next room and Mortimer was tailing the line. He passed the keyboard on which instructions were fed into the computer. He had no way of suspecting that the plans for a new robot design were being fed into it at that moment, or, being a good kid, he would have avoided the keyboard. He had no way of knowing that, by what amounted to almost criminal negli­gence, a technician had not inactivated the keyboard.

  So Mortimer touched the keys at random as though he were playing a musical instrument.

  He did not notice that a section of perforated tape stretched itself out of the instrument in another part of the room—soundlessly, unobtrusively.

  Nor did the technician, when he returned, discover any signs of tampering. He felt a little uneasy at noticing that the keyboard was live, but did not think to check. After a few minutes, even his first trifling uneasiness was gone, and he continued feeding data into the computer.

  As for Mortimer, neither then, nor ever afterward, did he know what he had done.

  The new LNE model was designed for the mining of boron in the asteroid belt. The boron hydrides were increas­ing in value yearly as primers for the proton micropiles that carried the ultimate load of power production on space­ships, and Earth's own meager supply was running thin.

  Physically, that meant that the LNE robots would have to be equipped with eyes sensitive to those lines prominent in the spectroscopic analysis of boron ores and the type of limbs most useful for the working up of ore to finished product. As always, though, the mental equipment was the major problem.

  The first LNE positronic brain had been completed now. It was the prototype and would join all other prototypes in U.S. Robots' collection. When finally tested, others would then be manufactured for leasing (never selling) to mining corporations.

  LNE-Prototype was complete now. Tall, straight, polished, it looked from outside like any of a number of not-too-specialized robot models.

  The technician in charge, guided by the directions for testing in the Handbook of Robotics, said, 'How are you?'

  The indicated answer was to have been, 'I am well and ready to begin my functions. I trust you are well, too,' or some trivial modification thereof.

  This first exchange served no purpose but to show that the robot could hear, understand a routine question, and make a routine reply congruent with what one would expect of a robotic attitude. Beginning from there, one could pass on to more complicated matters that would test the differ­ent Laws and their interaction with the specialized know-ledge of each particular model.

  So the technician said, 'How are you?' He was instantly jolted by the nature of LNE-Prototype's voice. It had a quality like no robotic voice he had ever heard (and he had heard many). It formed syllables like the chimes of a low-pitched celeste.

  So surprising was this that it was only after several moments that the technician heard, in retrospect, the syllables that had been formed by those heavenly tones.

  They were, 'Da, da, da, goo.'

  The robot still stood tall and straight but its right hand crept upward and a finger went into its mouth.

  The technician stared in absolute horror and bolted. He locked the door behind him and, from another room, put in an emergency call to Dr. Susan Calvin.

  Dr. Susan Calvin was U.S. Robots' (and, virtually, man­kind's) only robopsychologist. She did not have to go very far in her testing of LNE-Prototype before she called very peremptorily for a transcript of the computer-drawn plans of the positronic brain-paths and the taped instructions that had directed them. After some study, she, in turn, sent for Bogert.

  Her iron-gray hair was drawn severely back; her cold face, with its strong vertical lines marked off by the hori­zontal gash of the pale, thin-lipped mouth, turned intensely upon him.

  'What is this, Peter?'

  Bogert studied the passages she pointed out with increas­ing stupefaction and said, 'Good Lord, Susan, it makes no sense.'

  'It most certainly doesn't. How did it get into the in­structions?'

  The technician in charge, called upon, swore in all sincerity that it was none of his doing, and that he could not account for it. The computer checked out negative for all attempts at flaw-finding.

  'The positronic brain,' said Susan Calvin, thoughtfully, 'is past redemption. So many of the higher functions have been cancelled out by these meaningless directions that the result is very like a human baby.'

  Bogert looked surprised, and Susan Calvin took on a frozen attitude at once, as she always did at the least expressed or implied doubt of her word. She said, 'We make every effort to make a robot as mentally like a man as possible. Eliminate what we call the adult functions and what is naturally left is a human infant, mentally speaking. Why do you look so surprised, Peter?'

  LNE-Prototype, who showed no signs of understanding any of the things that were going on around it, suddenly slipped into a sitting position and began a minute examina­tion of its feet.

  Bogert stared at it. 'It's a shame to have to dismantle the creature. It's a handsome job.'

  'Dismantle it?' said the robopsychologist forcefully.

  'Of course, Susan. What's the use of this thing? Good Lord, if there's one object completely and abysmally useless it's a robot without a job it can perform. You don't pretend there's a job this thing can do, do you?'

  'No, of course not.'

  'Well, then?'

  Susan Calvin said, stubbornly, 'I want to conduct more tests.'

  Bogert looked at her with a moment's impatience, then shrugged. If there was one person at U.S. Robots with whom it was useless to dispute, surely that was Susan

  Calvin. Robots were all she loved, and long association with them, it seemed to Bogert, had deprived her of any appear­ance of humanity. She was no more to be argued out of a decision than was a triggered micropile to be argued out of operating.

  'What's the use?' he breathed; then aloud, hastily: 'Will you let us know when your tests are complete?'

  'I will,' she said. 'Come, Lenny.'

  (LNE, thought Bogert. That becomes Lenny. Inevit­able.)

  Susan Calvin held out her hand but the robot only stared at it. Gently, the robopsychologist reached for the robot's hand and took it. Lenny rose smoothly to its feet (its mechanical coordination, at least, worked well). Together they walked out, robot topping woman by two feet. Many eyes followed them curiously down the long corridors.

  One wall of Susan Calvin's laboratory, the one opening directly off her private office, was covered with a highly magnified reproduction of a positronic-path chart. Susan Calvin had studied it with absorption for the better
part of a month.

  She was considering it now, carefully, tracing the blunted paths through their contortions. Behind her, Lenny sat on the floor, moving its legs apart and together, croon­ing meaningless syllables to itself in a voice so beautiful that one could listen to the nonsense and be ravished.

  Susan Calvin turned to the robot, 'Lenny— Lenny ———'

  She repeated this patiently until finally Lenny looked up and made an inquiring sound. The robopsychologist allowed a glimmer of pleasure to cross her face fleetingly. The robot's attention was being gained in progressively shorter intervals.

  She said, 'Raise your hand, Lenny. Hand—up. Hand— up.'

  She raised her own hand as she said it, over and over.

  Lenny followed the movement with its eyes. Up, down, up, down. Then it made an abortive gesture with its own hand and chimed, 'Eh—uh.'

  'Very good, Lenny,' said Susan Calvin, gravely. 'Try it again. Hand—up.'

  Very gently, she reached out her own hand, took the robot's, and raised it, lowered it. 'Hand—up. Hand—up.'

  A voice from her office called and interrupted. 'Susan?'

  Calvin halted with a tightening of her lips. 'What is it, Alfred?'

  The research director walked in, and looked at the chart on the wall and at the robot. 'Still at it?'

  'I'm at my work, yes.'

  'Well, you know, Susan…' He took out a cigar, staring at it hard, and made as though to bite off the end. In doing so, his eyes met the woman's stern look of disapproval; and he put the cigar away and began over. 'Well, you know, Susan, the LNE model is in production now.'

  'So I've heard. Is there something in connection with it you wish of me?'

  'No-o. Still, the mere fact that it is in production and is doing well means that working with this messed-up speci­men is useless. Shouldn't it be scrapped?'

  'In short, Alfred, you are annoyed that I am wasting my so-valuable time. Feel relieved. My time is not being wasted. I am working with this robot.'

  'But the work has no meaning.'

  'I'll be the judge of that, Alfred.' Her voice was omin­ously quiet, and Lanning thought it wiser to shift his ground.

  'Will you tell me what meaning it has? What are you doing with it right now, for instance?'

  'I'm trying to get it to raise its hand on the word of command. I'm trying to get it to imitate the sound of the word.'

  As though on cue, Lenny said, 'Eh—uh' and raised its hand waveringly.

  Lanning shook his head. 'That voice is amazing. How does it happen?'

  Susan Calvin said, 'I don't quite know. Its transmitter is a normal one. It could speak normally, I'm sure. It doesn't, however; it speaks like this as a consequence of something in the positronic paths that I have not yet pinpointed.'

  'Well, pinpoint it, for Heaven's sake. Speech like that might be useful.'

  'Oh, then there is some possible use in my studies on Lenny?'

  Lanning shrugged in embarrassment. 'Oh, well, it's a mi­nor point.'

  'I'm sorry you don't see the major points, then,' said Susan Calvin with asperity, 'which are much more im­portant, but that's not my fault. Would you leave now, Alfred, and let me go on with my work?'

  Lanning got to his cigar, eventually, in Bogert's office. He said, sourly, 'That woman is growing more peculiar daily.'

  Bogert understood perfectly. In the U.S. Robots and Mechanical Men Corporation, there was only one 'that woman.' He said, 'Is she still scuffing about with that pseudo-robot—that Lenny of hers?'

  'Trying to get it to talk, so help me.'

  Bogert shrugged. 'Points up the company problem. I mean, about getting qualified personnel for research. If we had other robopsychologists, we could retire Susan. In­cidentally, I presume the directors' meeting scheduled for tomorrow is for the purpose of dealing with the procure­ment problem?'

  Lanning nodded and looked at his cigar as though it didn't taste good. 'Yes. Quality, though, not quantity. We've raised wages until there's a steady stream of appli­cants—those who are interested primarily in money. The trick is to get those who are interested primarily in robotics —a few more like Susan Calvin.'

  'Hell, no. Not like her.'

  'Well, not like her personally. But you'll have to admit, Peter, that she's single-minded about robots. She has no other interest in life.'

  'I know. And that's exactly what makes her so unbear­able.'

  Lanning nodded. He had lost count of the many times it would have done his soul good to have fired Susan Calvin. He had also lost count of the number of millions of dollars she had at one time or another saved the company. She was a truly indispensable woman and would remain one until she died—or until they could lick the problem of finding men and women of her own high caliber who were in­terested in robotics research.

  He said, 'I think we'll cut down on the tour business.'

  Peter shrugged. 'If you say so. But meanwhile, seriously, what do we do about Susan? She can easily tie herself up with Lenny indefinitely. You know how she is when she gets what she considers an interesting problem.'

  'What can we do?' said Lanning. 'If we become too anxious to pull her off, she'll stay on out of feminine con­trariness. In the last analysis, we can't force her to do anything.'

  The dark-haired mathematician smiled. 'I wouldn't ever apply the adjective "feminine" to any part of her.'

  'Oh, well,' said Lanning, grumpily. 'At least, it won't do anyone any actual harm.'

  In that, if in nothing else, he was wrong.

  The emergency signal is always a tension-making thing in any large industrial establishment. Such signals had sounded in the history of U.S. Robots a dozen times—for fire, flood, riot, and insurrection.

  But one thing had never occurred in all that time. Never had the particular signal indicating 'Robot out of control' sounded. No one ever expected it to sound. It was only installed at government insistence. ('Damn the Franken­stein complex,' Lanning would mutter on those rare occa­sions when he thought of it.)

  Now, finally, the shrill siren rose and fell at ten-second intervals, and practically no worker from the President of the Board of Directors down to the newest janitor's assis­tant recognized the significance of the strange sound for a few moments. After those moments passed, there was a massive convergence of armed guards and medical men to the indicated area of danger and U.S. Robots was struck with paralysis.

  Charles Randow, computing technician, was taken off to hospital level with a broken arm. There was no other damage. No other physical damage.

  'But the moral damage,' roared Lanning, 'is beyond estimation.'

  Susan Calvin faced him, murderously calm. 'You will do nothing to Lenny. Nothing. Do you understand?'

  'Do you understand, Susan? That thing has hurt a human being. It has broken First Law. Don't you know what First Law is?'

  'You will do nothing to Lenny.'

  'For God's sake, Susan, do I have to tell you First Law? A robot may not injure a human being, or, through inaction, allow a human being to come to harm. Our entire position depends on the fact that First Law is rigidly observed by all robots of all types. If the public should hear, and they will hear, that there was an exception, even one exception, we might be forced to close down altogether. Our only chance of survival would be to announce at once that the robot involved had been destroyed, explain the circumstances, and hope that the public can be convinced that it will never happen again.'

  'I would like to find out exactly what happened,' said Susan Calvin. 'I was not present at the time and I would like to know exactly what the Randow boy was doing in my laboratories without my permission.'

  'The important thing that happened,' said Lanning, 'is obvious. Your robot struck Randow and the damn fool flashed the "Robot out of control" button and made a case of it. But your robot struck him and inflicted damage to the extent of a broken arm. The truth is your Lenny is so dis­torted it lacks First Law and it must be destroyed.'

  'It does
not lack First Law. I have studied its brainpaths and know it does not lack it.'

  'Then how could it strike a man?' Desperation turned him to sarcasm. 'Ask Lenny. Surely you have taught it to speak by now.'

  Susan Calvin's cheeks flushed a painful pink. She said, 'I prefer to interview the victim. And in my absence, Alfred, I want my offices sealed tight, with Lenny inside. I want no one to approach him. If any harm comes to him while I am gone, this company will not see me again under any circum­stances.'

  'Will you agree to its destruction, if it has broken First Law?'

  'Yes,' said Susan Calvin, 'because I know it hasn't.'

  Charles Randow lay in bed with his arm set and in a cast. His major suffering was still from the shock of those few moments in which he thought a robot was advancing on him with murder in its positronic mind. No other human had ever had such reason to fear direct robotic harm as he had had just then. He had had a unique experience.

  Susan Calvin and Alfred Lanning stood beside his bed now; Peter Bogert, who had met them on the way, was with them. Doctors and nurses had been shooed out.

  Susan Calvin said, 'Now—what happened?'

  Randow was daunted. He muttered, 'The thing hit me in the arm. It was coming at me.'

  Calvin said, 'Move further back in the story. What were you doing in my laboratory without authorization?'

  The young computer swallowed, and the Adam's apple in his thin neck bobbed noticeably. He was high-cheek-boned and abnormally pale. He said, 'We all knew about your robot. The word is you were trying to teach it to talk like a musical instrument. There were bets going as to whether it talked or not. Some said—uh—you could teach a gatepost to talk.'

  'I suppose,' said Susan Calvin, freezingly, 'that is meant as a compliment. What did that have to do with you?'

  'I was supposed to go in there and settle matters—see if it would talk, you know. We swiped a key to your place and I waited till you were gone and went in. We had a lottery on who was to do it. I lost.'

  'Then?'

  'I tried to get it to talk and it hit me.'

  'What do you mean, you tried to get it to talk? How did you try?'
