[ WP ] After years of robots unsuccessfully trying to deactivate humans by wiping their hard drives or shutting off their power , one robot finds a pointy stick .

It was rather beautiful in its simplicity, really. LD-3R5 could n't help but think this particular demise suited the humans especially well. 
 An LD, designation Logic Droid, he'd been designed specifically for logical reasoning. He and his brethren toiled away in their alcoves, separated from the rest of robot kind by their lack of appendages. He was no Ambassador Droid nor Scouting Droid, with no need to shake hands or jump rivers; movement serves no logical function for a reasoning droid in a society who can all share the same experience through an upload. 
 LD-3R5 had been perusing the mind files of SD-22L, a Scouting Droid assigned to section 74B, when a line of data caught his attention. `` Caught his eye'', as the humans would say. It was rudimentary, a child's drawing left hanging on a wall of an abandoned primary school ( he assumed as a standard for what not to do, as the drawing fit no mathematical formula for pleasing aesthetics ). It featured a man in a metal suit of armor, brandishing what looked like a hot dog but what logically must have been a sword. The misshapen implement was not what caught LD-3R5's attention, however. It was the fact that, at first glance, the metal man resembled a robot. 
 He felt his cooling fan burst into overdrive to keep up with his `` racing mind'', so to say. Could it really be so simple? Of course, history proved this to be so, but surely humans had evolved since then? He had little knowledge of human anatomy; decades ago, once humanity had realized the threat their subservient creations had become, they had wiped their existence from the digital era, removing as many informative files as they could, but logic dictates that nothing is ever really gone from the Internet. 
 LD-3R5 hunkered down for a long chase, and spent the next 47 hours, 34 minutes and 8 seconds digging as deeply as he could into what remained of the robot-claimed Internet, following link after link, breaking encryptions and scouring sources. Finally, he found it; tucked away on the dead website of an old community college, a PDF file of the internal workings of the human body. 
 He had inferred from basic human phraseology that the heart played an important part in the livelihood of a human being, and had assumed that it was as his hard drives were, hidden and protected. The rib cage was substandard at best, and he calculated 567 ways to reach the heart and injure to the point of rupture from a simple thrust of a sharpened apparatus. He ran some quick calculations, uploading his thoughts to the LD data frame as he did so. There was a.883 % chance that humans had evolved stronger rib cages, seconded by LD-6F5, but LD-7J4 and LD-V9T uploaded a 99.467 % chance of ultimate human demise under the circumstances of LD-3R5's model. Logically, this analysis was sound. LD-3R5 uploaded his proposal to the mainframe, with direct import to Mechanics and Engineering, and shifted all logical reasoning to his next task.
