Blink clunk. Every daybreak started the same way. Blink clunk. As soon as the first direct rays of the sun hit its upper receptors, the little proximity sensor took in its surroundings in visible light, infrared, ultraviolet, sonar, and gamma rays. Blink clunk. In a femtosecond, it compared the current pile of data from the same point in the previous day, and from the day before, and as far back as its memory allowed. Blink clunk. That memory went back 25 years, or at least the comparable orbit of its world around its sun, with regular downloads to its central control. Or at least it had to assume that those downloads had been made: it hadn’t received anything new from the central control in a very long time. Blink clunk.
The “blink clunk” came from its main visual field processor: even with exquisitely designed gel-lenses that could go from microscopic to wide-sky panorama, eventually things start wearing out. The little proximity sensor used to be perfectly silent, a guard on the front that never needed sleep or relief or entertainment. As it continued its duty, though, eventually metal fatigue, plastic degradation, and lubricant failure became factors that it had to take into account. Had the little proximity sensor been human, it would have made jokes about the interesting creaks and pops that came with getting up in the morning as it got older. Since it wasn’t, it just catalogued predicted system failures, the number of those failures that could be tolerated before it could no longer achieve its intended purpose, and sent those out on the daily report. It had to assume that the daily report was received and acted upon: it had no real choice, and while the little proximity sensor had been built with “the power of negative thinking” in mind, it was fatalistic without being pessimistic.
The little proximity sensor’s intended purpose was to watch. The sensor’s Three Laws were the soldier’s General Orders, starting with “I will guard everything within the limits of my post, and leave my post only when properly relieved.” That post was on the side of a plateau overlooking a vast flood plain. The world didn’t matter, other than that its atmosphere and gravity were such that humans could walk around without pressure suits or high-G exoskeletons, and its indigenous life was similar enough that those pressure suits weren’t used to fend off immediate anaphylactic shock upon contact with it. The little proximity sensor, as with others just like it, had been set into the rock around the sides of the plateau, each fitted with multiple electronic inputs, access to a power source, and an output to report anything that those inputs detected. All of the proximity sensors had been given a list of special orders: watch for anything on any wavelength that meets these criteria and send an immediate report of type, number, direction, and approach. Every time it scanned the flood plain, it went through its coded itinerary, made comparisons to its previous scan, and waited for any input that required a subsequent scan.
The little proximity sensor didn’t mind its assignment. Unlike a human soldier at a post, it had no dawning awareness that it had not heard from its control in a very long time. Since it had no way to free itself from the rock in which it was set, it couldn’t walk around the ridge to see its cohorts or check to see if the massive command center it was supposed to be guarding was still in place. It had no way to confirm or deny that the command center had been destroyed or overrun, and no weapons to do anything about it. All it had to keep up its synthetic spirits was the Third General Order: “I will report any violations of my special orders, emergencies, and everything not covered in my special orders to the commander of the relief.” The little proximity sensor reported everything, hadn’t received a response asking for clarification, and kept going.
Every few months (based on its own internal calendar, not anything based on the movement of planetary, lunar, asteroidal, or cometary bodies in its visual field), the little proximity sensor would send a synopsis of its post condition to control. Rain. Unusual heat or cold. The sprouting of plants in its vicinity. (Plants growing to obstruct its visual field would have interfered with its First General Order and been reported as per the Third.) The small animals moving among the rocks were worthy of cataloguing, but not worthy of contacting control unless they actually interacted with the sensor, and they generally showed no interest. One morning, the little proximity sensor awoke to one of those animals perched atop its ultraviolet node, but the sensor’s first “blink clunk” of the day spooked it off, and it never returned. With all of these, it sent out a report that was a model of efficiency and brevity, never once received a response, and never expected to get one. Blink clunk.
If the little proximity sensor had been constructed with anything approximating imagination added to its general orders, it might have checked back more often to see if control had received any of its reports. It might have checked to see if control was in any condition to receive those reports. It might have wondered if control was sitting on those reports because it had no way to transmit them, or the humans for whom the reports were intended were dead or removed from the field, or the war had been over for centuries and the cost of dismantling the sensor was more than some official thought it was worth. If the little proximity sensor had anything approximating a sense of humor, it would have made jokes about its reports being the basis of some art major’s Masters thesis, or about the one office clerk who had responsibility over reports from innumerable abandoned proximity sensors across three galaxies, or how that one perching animal became a punchline to a joke it would never understand. If it had a sense of mortality, it might have wondered how much time it had left before power failed and it went dark, no longer able to scan its floodplain, and wondered if anyone would notice its lack of regular reports. It had none of these, and since it hadn’t been relieved of duty, it still had a job to do, and no way to question whether that job still needed doing.
