I, Robot

‘Robbie!’ Her shriek pierced the air, and one of the robots about the table faltered and dropped the tool he was holding. Gloria went almost mad with joy. Squeezing through the railing before either parent could stop her, she dropped lightly to the floor a few feet below, and ran toward her Robbie, arms waving and hair flying.

And the three horrified adults, as they stood frozen in their tracks, saw what the excited little girl did not see, – a huge, lumbering tractor bearing blindly down upon its appointed track.

It took split-seconds for Weston to come to his senses, and those split-seconds meant everything, for Gloria could not be overtaken. Although Weston vaulted the railing in a wild attempt, it was obviously hopeless. Mr Struthers signaled wildly to the overseers to stop the tractor, but the overseers were only human and it took time to act.

It was only Robbie that acted immediately and with precision.

With metal legs eating up the space between himself and his little mistress he charged down from the opposite direction. Everything then happened at once. With one sweep of an arm, Robbie snatched up Gloria, slackening his speed not one iota, and, consequently, knocking every breath of air out of her. Weston, not quite comprehending all that was happening, felt, rather than saw, Robbie brush past him, and came to a sudden bewildered halt. The tractor intersected Gloria’s path half a second after Robbie had, rolled on ten feet further and came to a grinding, long-drawn-out stop.

Gloria regained her breath, submitted to a series of passionate hugs on the part of both her parents and turned eagerly toward Robbie. As far as she was concerned, nothing had happened except that she had found her friend.

But Mrs Weston’s expression had changed from one of relief to one of dark suspicion. She turned to her husband, and, despite her disheveled and undignified appearance, managed to look quite formidable, ‘You engineered this, didn’t you?’

George Weston swabbed at a hot forehead with his handkerchief. His hand was unsteady, and his lips could curve only into a tremulous and exceedingly weak smile.

Mrs Weston pursued the thought, ‘Robbie wasn’t designed for engineering or construction work. He couldn’t be of any use to them. You had him placed there deliberately so that Gloria would find him. You know you did.’

‘Well, I did,’ said Weston. ‘But, Grace, how was I to know the reunion would be so violent? And Robbie has saved her life; you’ll have to admit that. You can’t send him away again.’

Grace Weston considered. She turned toward Gloria and Robbie and watched them abstractedly for a moment. Gloria had a grip about the robot’s neck and would have asphyxiated any creature but one of metal, and was prattling nonsense in half-hysterical frenzy. Robbie’s chrome-steel arms (capable of bending a bar of steel two inches in diameter into a pretzel) wound about the little girl gently and lovingly, and his eyes glowed a deep, deep red.

‘Well,’ said Mrs Weston, at last, ‘I guess he can stay with us until he rusts.’

Susan Calvin shrugged her shoulders, ‘Of course, he didn’t. That was 1998. By 2002, we had invented the mobile speaking robot which, of course, made all the non-speaking models out of date, and which seemed to be the final straw as far as the non-robot elements were concerned. Most of the world governments banned robot use on Earth for any purpose other than scientific research between 2003 and 2007.’

‘So that Gloria had to give up Robbie eventually?’

‘I’m afraid so. I imagine, however, that it was easier for her at the age of fifteen than at eight. Still, it was a stupid and unnecessary attitude on the part of humanity. US Robots hit its low point, financially, just about the time I joined them in 2007. At first, I thought my job might come to a sudden end in a matter of months, but then we simply developed the extra-Terrestrial market.’

‘And then you were set, of course.’

‘Not quite. We began by trying to adapt the models we had on hand. Those first speaking models, for instance. They were about twelve feet high, very clumsy and not much good. We sent them out to Mercury to help build the mining station there, but that failed.’

I looked up in surprise, ‘It did? Why, Mercury Mines is a multi-billion-dollar concern.’

‘It is now, but it was a second attempt that succeeded. If you want to know about that, young man, I’d advise you to look up Gregory Powell. He and Michael Donovan handled our most difficult cases in the teens and twenties. I haven’t heard from Donovan in years, but Powell is living right here in New York. He’s a grandfather now, which is a thought difficult to get used to. I can only think of him as a rather young man. Of course, I was younger, too.’

I tried to keep her talking, ‘If you would give me the bare bones, Dr Calvin, I can have Mr Powell fill it in afterward.’ (And this was exactly what I later did.)

She spread her thin hands out upon the desk and looked at them. ‘There are two or three,’ she said, ‘that I know a little about.’

‘Start with Mercury,’ I suggested.

‘Well, I think it was in 2015 that the Second Mercury Expedition was sent out. It was exploratory and financed in part by US Robots and in part by Solar Minerals. It consisted of a new-type robot, still experimental; Gregory Powell; Michael Donovan—’

Runaround

It was one of Gregory Powell’s favorite platitudes that nothing was to be gained from excitement, so when Mike Donovan came leaping down the stairs toward him, red hair matted with perspiration, Powell frowned.

‘What’s wrong?’ he said. ‘Break a fingernail?’

‘Yaaaah,’ snarled Donovan, feverishly. ‘What have you been doing in the sublevels all day?’ He took a deep breath and blurted out, ‘Speedy never returned.’

Powell’s eyes widened momentarily and he stopped on the stairs; then he recovered and resumed his upward steps. He didn’t speak until he reached the head of the flight, and then:

‘You sent him after the selenium?’

‘Yes.’

‘And how long has he been out?’

‘Five hours now.’

Silence! This was a devil of a situation. Here they were, on Mercury exactly twelve hours – and already up to the eyebrows in the worst sort of trouble. Mercury had long been the jinx world of the System, but this was drawing it rather strong – even for a jinx.

Powell said, ‘Start at the beginning, and let’s get this straight.’

They were in the radio room now – with its already subtly antiquated equipment, untouched for the ten years previous to their arrival. Even ten years, technologically speaking, meant so much. Compare Speedy with the type of robot they must have had back in 2005. But then, advances in robotics these days were tremendous. Powell touched a still gleaming metal surface gingerly. The air of disuse that touched everything about the room – and the entire Station – was infinitely depressing.

Donovan must have felt it. He began: ‘I tried to locate him by radio, but it was no go. Radio isn’t any good on the Mercury Sunside – not past two miles, anyway. That’s one of the reasons the First Expedition failed. And we can’t put up the ultrawave equipment for weeks yet—’

‘Skip all that. What did you get?’

‘I located the unorganized body signal in the short wave. It was no good for anything except his position. I kept track of him that way for two hours and plotted the results on the map.’

There was a yellowed square of parchment in his hip pocket – a relic of the unsuccessful First Expedition – and he slapped it down on the desk with vicious force, spreading it flat with the palm of his hand. Powell, hands clasped across his chest, watched it at long range.

Donovan’s pencil pointed nervously. ‘The red cross is the selenium pool. You marked it yourself.’

‘Which one is it?’ interrupted Powell. ‘There were three that MacDougal located for us before he left.’

‘I sent Speedy to the nearest, naturally. Seventeen miles away. But what difference does that make?’ There was tension in his voice. ‘There are the penciled dots that mark Speedy’s position.’

And for the first time Powell’s artificial aplomb was shaken and his hands shot forward for the map.

‘Are you serious? This is impossible.’

‘There it is,’ growled Donovan.

The little dots that marked the position formed a rough circle about the red cross of the selenium pool. And Powell’s fingers went to his brown mustache, the unfailing signal of anxiety.

Donovan added: ‘In the two hours I checked on him, he circled that damned pool four times. It seems likely to me that he’ll keep that up forever. Do you realize the position we’re in?’

Powell looked up shortly, and said nothing. Oh, yes, he realized the position they were in. It worked itself out as simply as a syllogism. The photo-cell banks that alone stood between the full power of Mercury’s monstrous sun and themselves were shot to hell. The only thing that could save them was selenium. The only thing that could get the selenium was Speedy. If Speedy didn’t come back, no selenium. No selenium, no photo-cell banks. No photobanks – well, death by slow broiling is one of the more unpleasant ways of being done in.

Donovan rubbed his red mop of hair savagely and expressed himself with bitterness. ‘We’ll be the laughing stock of the System, Greg. How can everything have gone so wrong so soon? The great team of Powell and Donovan is sent out to Mercury to report on the advisability of reopening the Sunside Mining Station with modern techniques and robots and we ruin everything the first day. A purely routine job, too. We’ll never live it down.’

‘We won’t have to, perhaps,’ replied Powell, quietly. ‘If we don’t do something quickly, living anything down – or even just plain living – will be out of the question.’

‘Don’t be stupid! If you feel funny about it, Greg, I don’t. It was criminal, sending us out here with only one robot. And it was your bright idea that we could handle the photo-cell banks ourselves.’

‘Now you’re being unfair. It was a mutual decision and you know it. All we needed was a kilogram of selenium, a Stillhead Dielectrode Plate and about three hours’ time – and there are pools of pure selenium all over Sunside. MacDougal’s spectroreflector spotted three for us in five minutes, didn’t it? What the devil! We couldn’t have waited for next conjunction.’

‘Well, what are we going to do? Powell, you’ve got an idea. I know you have, or you wouldn’t be so calm. You’re no more a hero than I am. Go on, spill it!’

‘We can’t go after Speedy ourselves, Mike – not on the Sunside. Even the new insosuits aren’t good for more than twenty minutes in direct sunlight. But you know the old saying, “Set a robot to catch a robot.” Look, Mike, maybe things aren’t so bad. We’ve got six robots down in the sublevels, that we may be able to use, if they work. If they work.’

There was a glint of sudden hope in Donovan’s eyes. ‘You mean six robots from the First Expedition. Are you sure? They may be subrobotic machines. Ten years is a long time as far as robot-types are concerned, you know.’

‘No, they’re robots. I’ve spent all day with them and I know. They’ve got positronic brains: primitive, of course.’ He placed the map in his pocket. ‘Let’s go down.’

The robots were on the lowest sublevel – all six of them surrounded by musty packing cases of uncertain content. They were large, extremely so, and even though they were in a sitting position on the floor, legs straddled out before them, their heads were a good seven feet in the air.

Donovan whistled. ‘Look at the size of them, will you? The chests must be ten feet around.’

‘That’s because they’re supplied with the old McGuffy gears. I’ve been over the insides – crummiest set you’ve ever seen.’

‘Have you powered them yet?’

‘No. There wasn’t any reason to. I don’t thing there’s anything wrong with them. Even the diaphragm is in reasonable order. They might talk.’

He had unscrewed the chest plate of the nearest as he spoke, inserted the two-inch sphere that contained the tiny spark of atomic energy that was a robot’s life. There was difficulty in fitting it, but he managed, and then screwed the plate back on again in laborious fashion. The radio controls of more modern models had not been heard of ten years earlier. And then to the other five.

Donovan said uneasily, ‘They haven’t moved.’

‘No orders to do so,’ replied Powell, succinctly. He went back to the first in the line and struck him on the chest. ‘You! Do you hear me?’

The monster’s head bent slowly and the eyes fixed themselves on Powell. Then, in a harsh, squawking voice – like that of a medieval phonograph, he grated, ‘Yes, Master!’

Powell grinned humorlessly at Donovan. ‘Did you get that? Those were the days of the first talking robots when it looked as if the use of robots on Earth would be banned. The makers were fighting that and they built good, healthy slave complexes into the damned machines.’

‘It didn’t help them,’ muttered Donovan.

‘No, it didn’t, but they sure tried.’ He turned once more to the robot. ‘Get up!’

The robot towered upward slowly and Donovan’s head craned and his puckered lips whistled.

Powell said: ‘Can you go out upon the surface? In the light?’

There was consideration while the robot’s slow brain worked. Then, ‘Yes, Master.’

‘Good. Do you know what a mile is?’

Another consideration, and another slow answer. ‘Yes, Master.’

‘We will take you up to the surface then, and indicate a direction. You will go about seventeen miles, and somewhere in that general region you will meet another robot, smaller than yourself. You understand so far?’

‘Yes, Master.’

‘You will find this robot and order him to return. If he does not wish to, you are to bring him back by force.’

Donovan clutched at Powell’s sleeve. ‘Why not send him for the selenium direct?’

‘Because I want Speedy back, nitwit. I want to find out what’s wrong with him.’ And to the robot, ‘All right, you, follow me.’

The robot remained motionless and his voice rumbled: ‘Pardon, Master, but I cannot. You must mount first.’ His clumsy arms had come together with a thwack, blunt fingers interlacing.

Powell stared and then pinched at his mustache. ‘Uh … oh!’

Donovan’s eyes bulged. ‘We’ve got to ride him? Like a horse?’

‘I guess that’s the idea. I don’t know why, though. I can’t see – yes, I do. I told you they were playing up robot-safety in those days. Evidently, they were going to sell the notion of safety by not allowing them to move about without a mahout on their shoulders all the time. What do we do now?’

‘That’s what I’ve been thinking,’ muttered Donovan. ‘We can’t go out on the surface, with a robot or without. Oh, for the love of Pete’ – and he snapped his fingers twice. He grew excited. ‘Give me that map you’ve got. I haven’t studied it for two hours for nothing. This is a Mining Station. What’s wrong with using the tunnels?’

The Mining Station was a black circle on the map, and the light dotted lines that were tunnels stretched out about it in spiderweb fashion.

Donovan studied the list of symbols at the bottom of the map. ‘Look,’ he said, ‘the small black dots are openings to the surface, and here’s one maybe three miles away from the selenium pool. There’s a number here – you’d think they’d write larger – 13a. If the robots know their way around here—’

Powell shot the question and received the dull ‘Yes, Master,’ in reply. ‘Get your insosuit,’ he said with satisfaction.

It was the first time either had worn the insosuits – which marked one time more than either had expected to upon their arrival the day before – and they tested their limb movements uncomfortably.

The insosuit was far bulkier and far uglier than the regulation spacesuit; but withal considerably lighter, due to the fact that they were entirely nonmetallic in composition. Composed of heat-resistant plastic and chemically treated cork layers, and equipped with a desiccating unit to keep the air bone-dry, the insosuits could withstand the full glare of Mercury’s sun for twenty minutes. Five to ten minutes more, as well, without actually killing the occupant.

And still the robot’s hands formed the stirrup, nor did he betray the slightest atom of surprise at the grotesque figure into which Powell had been converted.

Powell’s radio-harshened voice boomed out: ‘Are you ready to take us to Exit 13a?’

‘Yes, Master.’

Good, thought Powell; they might lack radio control but at least they were fitted for radio reception. ‘Mount one or the other, Mike,’ he said to Donovan.

He placed a foot in the improvised stirrup and swung upward. He found the seat comfortable; there was the humped back of the robot, evidently shaped for the purpose, a shallow groove along each shoulder for the thighs and two elongated ‘ears’ whose purpose now seemed obvious.

Powell seized the ears and twisted the head. His mount turned ponderously. ‘Lead on, Macduff.’ But he did not feel at all light-hearted.

The gigantic robots moved slowly, with mechanical precision, through the doorway that cleared their heads by a scant foot, so that the two men had to duck hurriedly, along a narrow corridor in which their unhurried footsteps boomed monotonously and into the air lock.

The long, airless tunnel that stretched to a pinpoint before them brought home forcefully to Powell the exact magnitude of the task accomplished by the First Expedition, with their crude robots and their start-from-scratch necessities. They might have been a failure, but their failure was a good deal better than the usual run of the System’s successes.

The robots plodded onward with a pace that never varied and with footsteps that never lengthened.

Powell said: ‘Notice that these tunnels are blazing with lights and that the temperature is Earth-normal. It’s probably been like this all the ten years that this place has remained empty.’

‘How’s that?’

‘Cheap energy; cheapest in the System. Sunpower, you know and on Mercury’s Sunside, sunpower is something. That’s why the Station was built in the sunlight rather than in the shadow of a mountain. It’s really a huge energy converter. The heat is turned into electricity, light, mechanical work and what have you; so that energy is supplied and the Station is cooled in a simultaneous process.’

‘Look,’ said Donovan. ‘This is all very educational, but would you mind changing the subject? It so happens that this conversion of energy that you talk about is carried on by the photo-cell banks mainly – and that is a tender subject with me at the moment.’

Powell grunted vaguely, and when Donovan broke the resulting silence, it was to change the subject completely. ‘Listen, Greg. What the devil’s wrong with Speedy, anyway? I can’t understand it.’

It’s not easy to shrug shoulders in an insosuit, but Powell tried it. ‘I don’t know, Mike. You know he’s perfectly adapted to a Mercurian environment. Heat doesn’t mean anything to him and he’s built for the light gravity and the broken ground. He’s foolproof – or, at least, he should be.’

Silence fell. This time, silence that lasted.

‘Master,’ said the robot, ‘we are here.’

‘Eh?’ Powell snapped out of a semidrowse. ‘Well, get us out of here – out to the surface.’

They found themselves in a tiny substation, empty, airless, ruined. Donovan had inspected a jagged hole in the upper reaches of one of the walls by the light of his pocket flash.

‘Meteorite, do you suppose?’ he had asked.

Powell shrugged. ‘To hell with that. It doesn’t matter. Let’s get out.’

A towering cliff of a black, basaltic rock cut off the sunlight, and the deep night shadow of an airless world surrounded them. Before them, the shadow reached out and ended in knife-edge abruptness into an all-but-unbearable blaze of white light, that glittered from myriad crystals along a rocky ground.

‘Space!’ gasped Donovan. ‘It looks like snow.’ And it did. Powell’s eyes swept the jagged glitter of Mercury to the horizon and winced at the gorgeous brilliance.

‘This must be an unusual area,’ he said. ‘The general albedo of Mercury is low and most of the soil is gray pumice. Something like the Moon, you know. Beautiful, isn’t it?’

He was thankful for the light filters in their visiplates. Beautiful or not, a look at the sunlight through straight glass would have blinded them inside of half a minute.

Donovan was looking at the spring thermometer on his wrist. ‘Holy smokes, the temperature is eighty centigrade!’

Powell checked his own and said: ‘Um-m-m. A little high. Atmosphere, you know.’

‘On Mercury? Are you nuts?’

‘Mercury isn’t really airless,’ explained Powell, in absentminded fashion. He was adjusting the binocular attachments to his visiplate, and the bloated fingers of the insosuit were clumsy at it. ‘There is a thin exhalation that clings to its surface – vapors of the more volatile elements and compounds that are heavy enough for Mercurian gravity to retain. You know: selenium, iodine, mercury, gallium, potassium, bismuth, volatile oxides. The vapors sweep into the shadows and condense, giving up heat. It’s a sort of gigantic still. In fact, if you use your flash, you’ll probably find that the side of the cliff is covered with, say, hoar-sulphur, or maybe quicksilver dew.

‘It doesn’t matter, though. Our suits can stand a measly eighty indefinitely.’

Powell had adjusted the binocular attachments, so that he seemed as eye-stalked as a snail.

Donovan watched tensely. ‘See anything?’

The other did not answer immediately, and when he did, his voice was anxious and thoughtful. ‘There’s a dark spot on the horizon that might be the selenium pool. It’s in the right place. But I don’t see Speedy.’

Powell clambered upward in an instinctive striving for a better view, till he was standing in unsteady fashion upon his robot’s shoulders. Legs straddled wide, eyes straining, he said: ‘I think … I think— Yes, it’s definitely he. He’s coming this way.’

Donovan followed the pointing finger. He had no binoculars, but there was a tiny moving dot, black against the blazing brilliance of the crystalline ground.

‘I see him!’ he yelled. ‘Let’s get going!’

Powell had hopped down into a sitting position on the robot again, and his suited hand slapped against the Gargantuan’s barrel chest. ‘Get going!’

‘Giddy-ap!’ yelled Donovan, and thumped his heels, spur fashion.

The robots started off, the regular thudding of their footsteps silent in the airlessness, for the nonmetallic fabric of the insosuits did not transmit sound. There was only a rhythmic vibration just below the border of actual hearing.

‘Faster!’ yelled Donovan. The rhythm did not change.

‘No use,’ cried Powell, in reply. ‘These junk heaps are only geared to one speed. Do you think they’re equipped with selective flexors?’

They had burst through the shadow, and the sunlight came down in a white-hot wash and poured liquidly about them.

Donovan ducked involuntarily. ‘Wow! Is it imagination or do I feel heat?’

‘You’ll feel more presently,’ was the grim reply. ‘Keep your eye on Speedy.’

Robot SPD 13 was near enough to be seen in detail now. His graceful, streamlined body threw out blazing highlights as he loped with easy speed across the broken ground. His name was derived from his serial initials, of course, but it was apt, nevertheless, for the SPD models were among the fastest robots turned out by the United States Robots and Mechanical Men Corp.

‘Hey, Speedy,’ howled Donovan, and waved a frantic hand.
