"Tell me later," Johnny pleaded. "I want to get started. The longer we delay here the longer it will take until we're finished. And I still have that appointment with Diane tonight. I couldn't contact her during the day because she said she works with Starbuck. We've got to hurry." Westler's hands, guiding the complex tools, moved with swift efficiency, as if, indeed, he had worked with the Robots all his life. Wires were crossed, insulated, re-arranged. Gaps and relays were tested and retested, gears changed, long-unused parts oiled, cleaned, checked for defects. Surface plates were clamped into place over layers of insulation. At last the two Robots lay there, supine but--Westler hoped--ready for human use. "He's still watching," said Johnny. "Let him. We couldn't prevent him. Only hope he suddenly doesn't decide to come down here for a closer look or send for help. It seems amazing he's done neither so far." "Maybe he's asleep." "Robots do not sleep. I assure you. Well, it's ready." Westler reached into the Robots' interior before clamping on the final head plates. Each Robot stood up in ponderous silence. "You first, Johnny. I can clamp my plate from the inside. Are you sure my explanations on how to work this were satisfactory? Once inside we'll have to contact each other by signals only." "What about the radio sets inside? I don't know much about radio, but you said they worked." "They do, but the wavelength might be too close to a Robot wavelength and we'd give ourselves away. Remember, we are to be nothing more or less than two Robots once we climb inside. That way, there shouldn't be any trouble. All ready? Up you go." Johnny was boosted up, pulled himself within the cramped interior of the Robot. There was barely room for him to stand upright, his shoulders hunched, arms tight in front of him. A dizzying mass of dials and levers confronted him suddenly, and although Westler had explained them and diagrammed them and made Johnny memorize them, he was still bewildered by direct contact. He was almost afraid to try his first movement, lest the Robot remain immobile. The face plate slammed home. Johnny could see through the one-way plastic of the Robot's eyes as Westler climbed into his own machine. Johnny pulled the starting lever and felt his Robot lurch forward. Must learn to control the motion ... so ... he was now aware of a lumbering gait, of a steady advance toward the farther wall.... Something made him whirl and peer through the rear eyes. The Robot supervisor was coming toward them at a rate of speed they couldn't match. * * * * * "You see?" said Starbuck proudly. "I am no longer a servant. I suppose you would call me a junior executive now. But I'm on the way up. Definitely on the way up. In a while there is no telling how far I can go."
