Mark Rogers was a prospector, and he went to the asteroid belt looking for radioactives and rare metals. He searched for years, never finding much, hopping from fragment to fragment. After a time he settled on a slab of rock half a mile thick.
Rogers had been born old, and he didn’t age much past a point. His face was white with the pallor of space, and his hands shook a little. He called his slab of rock Martha, after no girl he had ever known.
He made a little strike, enough to equip Martha with an air pump and a shack, a few tons of dirt and some water tanks, and a robot. Then he settled back and watched the stars.
The robot he bought was a standard-model all-around worker, with built-in memory and a thirty-word vocabulary. Mark added to that, bit by bit. He was something of a tinkerer, and he enjoyed adapting his environment to himself.
At first, all the robot could say was “Yes, sir,” and “No, sir.” He could state simple problems: “The air pump is laboring, sir.” “The corn is budding, sir.” He could perform a satisfactory salutation: “Good morning, sir.”
Mark changed that. He eliminated the “sirs” from the robot’s vocabulary; equality was the rule on Mark’s hunk of rock. Then he dubbed the robot Charles, after a father he had never known.
As the years passed, the air pump began to labor a little as it converted the oxygen in the planetoid’s rock into a breathable atmosphere. The air seeped into space, and the pump worked a little harder, supplying more.
The crops continued to grow on the tamed black dirt of the planetoid. Looking up, Mark could see the sheer blackness of the river of space, the floating points of the stars. Around him, under him, overhead, masses of rock drifted, and sometimes the starlight glinted from their black sides. Occasionally, Mark caught a glimpse of Mars or Jupiter. Once he thought he saw Earth.
Mark began to tape new responses into Charles. He added simple responses to cue words. When he said, “How does it look?” Charles would answer, “Oh, pretty good, I guess.”
At first the answers were what Mark had been answering himself, in the long dialogue held over the years. But, slowly, he began to build a new personality into Charles.
Mark had always been suspicious and scornful of women. But for some reason he didn’t tape the same suspicion into Charles. Charles’ outlook was quite different.
“What do you think of girls?” Mark would ask, sitting on a packing case outside the shack, after the chores were done.
“Oh, I don’t know. You have to find the right one.” The robot would reply dutifully, repeating what had been put on its tape.
“I never saw a good one yet,” Mark would say.
“Well, that’s not fair. Perhaps you didn’t look long enough. There’s a girl in the world for every man.”
“You’re a romantic!” Mark would say scornfully. The robot would pause--a built-in pause--and chuckle a carefully constructed chuckle.
“I dreamed of a girl named Martha once,” Charles would say. “Maybe if I would have looked, I would have found her.”
And then it would be bedtime. Or perhaps Mark would want more conversation. “What do you think of girls?” he would ask again, and the discussion would follow its same course.
Charles grew old. His limbs lost their flexibility, and some of his wiring started to corrode. Mark would spend hours keeping the robot in repair.
“You’re getting rusty,” he would cackle.
“You’re not so young yourself,” Charles would reply. He had an answer for almost everything. Nothing involved, but an answer.
It was always night on Martha, but Mark broke up his time into mornings, afternoons and evenings. Their life followed a simple routine. Breakfast, from vegetables and Mark’s canned store. Then the robot would work in the fields, and the plants grew used to his touch. Mark would repair the pump, check the water supply, and straighten up the immaculate shack. Lunch, and the robot’s chores were usually finished.
The two would sit on the packing case and watch the stars. They would talk until supper, and sometimes late into the endless night.
In time, Mark built more complicated conversations into Charles. He couldn’t give the robot free choice, of course, but he managed a pretty close approximation of it. Slowly, Charles’ personality emerged. But it was strikingly different from Mark’s.
