Electronic law enforcement officers can step up the service already in the near future. American company Knightscope presented prototypes of robots, resembling hybrid R2-D2 from "Star Wars ". Models were named K5 and K10, have high autonomy and feature a variety of sensors, allowing to see in the dark, recognize faces and arms, record audio, detect anomalous behavior and inform the authorities at the first sign of trouble. K5 is smaller in size and will be used in an urban environment. K10 height of five feet, has a much greater autonomy, which allows him to travel long distances, providing control over the sparsely populated territories. Robots do not have any weapons, at least for now, so they will only be used for monitoring and warning.
