WASHINGTON — An autonomous robot given the task of guarding a mall and office complex apparently chose to end it all by drowning itself in a water fountain. <br /> <br />The Knightscope K5 robot drove into a water fountain at the Georgetown Waterfront in Washington on Tuesday, the Washington Post reported. <br /> <br />The K5 costs about $7 an hour to rent out, which is a big saving on the average $11 an hour cost of a human security guard. <br /> <br />The K5 is equipped with microphones, cameras and other sensors, and makes a whistling noise when it catches wrongdoers up to no good. <br /> <br />Last summer, a K5 knocked over a toddler, injuring the child’s leg, according to the Verge. In April this year, a man was arrested in Mountain View, California for knocking over a K5 while drunk.
