"In many sci-fi movies and television shows, we see a future world policed by robot law enforcement officers. These future robocops are often humanoid robots - robots designed to look human. In reality, these kinds of robocops and the superhuman powers they use to fight crime are a long way off, but there are many other types of robots already being used in law enforcement today. A robot is a moving machine that can be programmed to perform tasks and gather information from its surroundings. Law enforcement robots come in all sorts of shapes and sizes and are used in a variety of roles, from surveillance in dangerous situations, such as store holdups, to getting up close to and disarming bombs" -- From page 4.
