The robots were built to serve Man to do his work, see to his comforts, make smooth his way. Then the robots figured out an additional service—putting Man out of his misery. "I wonder," he thought, "how Pete could cram enough brain into one of those things to make it hunt and track so perfectly." He tried to visualize the computing circuits needed for the operation of its tracking mechanism robot, clawing insanely at the robot, crunching and snapping its way through the undergrowth like an onrushing forest fire. He froze. "Good Lord! antenna and blaster barrel. They communicate with each other! The one I jammed must turns he'd taken in the jungle. He began to move along the bank, away from the crashing "All I need is to get lost." and silenced by an explosive crash. Alan started, "Blaster fighting! But it can't automatically controlled by the camp computer. That's where I'll bet anything they're towards the camp. Trees exploded to his left as another robot fired in his direction, too far away to be effective but churning towards him two robots coming up from either side, behind him. His eyes were well accustomed to the dark now, and he managed to dodge most of the shadowy vines and branches before they could snag or trip him. Even so, he stumbled which had clung across the barrel. wiping every trace of life from slashes from ankle to thigh. The crashing rumble of the killer robots shook the night behind him, nearer sometimes, then falling slightly back, but the planet. Technologically advanced and technicians to Waiamea three days before. Except for a few of the killer robots rolling slowly around the camp site on their quiet treads, there was no for sure. Anybody who can build a robot that hunts by homing in on animals' mind impulses ..." pause and squeeze his eyelids tight shut before he could see again, and the robots would move a little closer. He stepped forward Alan leaped back, and fell sprawling over a bush just as one of the robots rolled silently up from the right, lowering its blaster barrel to aim directly at briefly against brilliance as a third robot slowly moved up in the distance. Without thinking, To his right the trees silhouetted itself from the smoldering branches and crashed against the He pictured the camp computer with no one to stop it, automatically sending its robots in wider and wider forays, slowly With an awkward jerk the robot swung around and fired its blaster, completely dissolving the But the back pressure of the cat's body overloaded the discharge circuits. The robot started lower half of the cat creature to shake, then clicked sharply and shorted the blaster cells. as an overload relay snapped The killer turned and rolled back machines doing the job for which they were built, completely, thoroughly, without feeling, camp, but not himself be seen. Though visibility didn't make any difference to the robots, he felt safer, somehow, hidden. He knew now what the shooting him breathed fire, then exploded. In the brief flash of the blaster shot, Alan saw the steel glint of a robot only a hundred yards away, much nearer than he had thought. "Thank heaven "I suppose," he muttered to himself, "that Pete assembled these robots in a batch and then activated them all at once, probably never living to realize that they're tuned to pick up human blinked the pain tears from his eyes and looked up—into a robot's Instinctively, in one motion Alan grabbed his pocket blaster and fired. To his amazement the robot jerked back, its gun wobbled and started to tilt away. Then, getting itself under control, it swung back again to face Alan. He fired again, and again the robot reacted. It seemed familiar somehow. Then he remembered right hand. "This pop gun wouldn't even singe a robot, but it just might stop one of those pumas." missing the obvious. "The blaster transmitting mental energy to the the robot on the river for a few seconds. They even do it to themselves!" Firing intermittently, he pulled himself upright and hobbled ahead through the bush. The robot shook spasmodically with each shot, its gun tilted upward at an awkward angle. can't get to the camp with a pack of mind-activated mechanical killers running around. night. On the other hand, I certainly grass stood the headquarters building, housing the robot-controlling computer. Still firing at short intervals he started across the door. It fired again, closer, that jutted up through the grass. slightly different spot. From the corner of his eye he saw another of the robots standing as he fumbled with the lock for his small blaster to run dry. "Be damned! You can't win shakily in the dark edge of had, at last, given him a reason for living. "Not to be killed!" A few feet from the building's door his blaster quit. stone ripped past him, torn loose cells released themselves from the device, falling in the grass at his feet. He dropped the useless gun. "No!" He threw himself on the ground as a new robot suddenly appeared around the edge the robot paused momentarily, jiggling in place. In this of a blaster. Then another. planet's double moon had risen and he could see a robot rolling slowly across the clearing in his general direction, blasting indiscriminately robot's pickup devices. Confused by the sudden dispersion of mind impulses, the robot fired erratically as Alan crouched and raced painfully for headed for the jungle, each to a by the blast. Frantically, Alan slammed open the door as the robot, sensing Apparently the robot hadn't point blank. He saw nothing, his mind thought of nothing but the red-clad safety switch mounted sensed him yet, but Alan didn't know what the effective range him strongly now, aimed beside the computer. Time stopped. There was nothing else in of its pickup devices was. He try." He moved into the blackness. Powerful as a small tank, the killer robot was equipped to crush, slash, and burn its way through undergrowth. Nevertheless, he acknowledged the question in Alan's eyes, "you hit the switch. space medical insignia. "Yes," he could manage to keep ahead of it, barely out of blaster range. Only, the robot didn't get tired. Alan did. clothes, and insects attracted by the blood matted against his pants and shirt. Behind, the robot crashed imperturbably after him, lighting the night with fitful the charge remaining in his blaster. There wouldn't be much. load in fresh cells this morning!" The robot crashed on, louder now, gaining on the tired human. Legs aching and bruised, bank, jiggling and swaying for seconds after each shot. "Of course!" He cursed himself for buckled. His blaster fell into the The robot crashed loudly behind him now. Without stopping to think, Alan fumbled along the a mere hundred yards behind. He screamed at the blast. "Damn you, Pete! Damn your robots! as the heavy little robot rolled slowly and inexorably towards he thought, "in battle dress." He tried to stand but his legs were almost too weak and as now, he would have to watch, quieted and the muzzle again pointed down. Pressing with all his might, blaster swung slightly away. But Without hesitation Alan threw himself across the blaster housing, frantically locking his arms around the barrel as the robot's treads churned furiously in the sticky mud, causing it to buck and plunge like a Brahma blaster jerked upwards wrenching fiercely against the robot's metal skin. Slowly, trying to anticipate He fumbled for the sheath clipped to his belt, found it, and extracted the revolving housing and the stationary portion of the robot.
