Utopia

The maintenance frame itself was attached to its base by a complex arrangement of three sets of rotating bearings, built at right angles to each other, so that the frame could be spun around into any conceivable orientation. Thus, a robot clamped into the frame could be spun and swiveled and rotated into whatever position was most convenient to the roboticist doing the work. Once the service robots had Kaelor up on the frame, Fredda stepped in and went to work. Not that she had much hope of success, but with the stakes this high, one had to at least try.

She swiveled Kaelor’s body around until he was lying facedown, his unpowered eyes staring blankly at the floor. She found Kaelor’s standard diagnostic port at the base of his neck and plugged in her test meter. She switched from one setting to another, watching the display on the meter. “No surprises there,” she said. “The standard diagnostics show that his basic circuits are all functioning normally, but we knew that.”

“Can you tap into his memory system through that port?” Davlo asked, leaning in a bit closer than Fredda would have preferred. He was nervous, agitated, his face gaunt and pale. He kept rubbing his hands together, over and over.

“I’m afraid not,” said Fredda, trying to assume a cool, professional tone. “It’s not that easy. This just shows me the basic systems status. Even though he’s powered down, there are still lots of circuits with trickle-charges running through them, things that need power to maintain system integrity. This just shows me he hasn’t blown a fuse, that his basic pathing is stable. Now I know we’re not going to harm him accidentally as we proceed.” Whether or not we decide to harm him deliberately is quite another story. she thought. No sense saying any such thing out loud. Lentrall was in a bad enough state as it was.

Fredda left the test meter plugged in and hung it off a utility hook on the side of the maintenance frame. She got in a little closer, adjusted the position of the table slightly, and undid the four clampdown fasteners that held on the back of Kaelor’s head, and carefully lifted the backplate off. She took one look at the circuitry and cabling thus revealed and shook her head. “No,” she said. “I was afraid of that. I’ve seen this setup before.” She pointed to a featureless black ball, about twelve centimeters across. “His positronic brain is in that fully sealed unit. The only link between it and the outside world is that armored cable coming out of its base, where the spinal column would be on a human. That cable will have about five thousand microcables inside, every one of them about the diameter of a human hair. I’d have to guess right on which two of those to link into, and get it right on the first try, or else I would quite literally fry his brain. Short him out. Space alone knows how long it would take to trace the linkages. A week probably. The whole brain assembly is designed to be totally inaccessible.”

“But why?” asked Davlo Lentrall.

Fredda smiled sadly. “To protect the confidential information inside his head. To keep people from doing exactly what we’re trying to do-get information out of him that he would not want to reveal.”

“Damnation! I’d thought we’d just be able to tap into his memory system and extract what we needed.”

“With some robots that might be possible-though incredibly time-consuming,” Fredda said as she reattached the back of Kaelor’s head. “Not with this model.”

“So there’s nothing we can do,” Lentrall said. “I mean, on the level of electronics and memory dumps. “As he spoke, his face was drawn and expressionless, and he seemed unwilling to meet Fredda’s gaze, or to look at Kaelor. He was the portrait of a man who had already decided he had to do something he was not going to be proud of. And the portrait of a man who was going to crack before very much longer.

“Nothing much,” said Fredda.

“So we’re going to have to talk to him-and we know he doesn’t want to talk.”

Fredda wanted to have some reason to disagree, but she knew better. Kaelor would already have spoken up if he had been willing to speak. “No, he doesn’t,” she said. She thought for a moment and picked up her test meter. “The two things I can do is deactivate his main motor control, so he can only move his head and eyes and talk. And I can set his pseudoclock-speed lower.”

“Why cut his main motor function?” Davlo asked.

So he won’t tear his own head off or smash his own brain in to keep us from learning what he wants kept secret, Fredda thought, but she knew better than to tell that to Davlo. Fortunately, it didn’t take her long to think of something else. “To keep him from breaking out and escaping,” she said. “He might try to run away rather than speak to us.”

Davlo nodded, a bit too eagerly, as if he knew better but wanted to believe. “What about the clock speed?” he asked.
