Robocops may be a ways off still, but robot security guards are already here. Security robot company Knightscope has two different guard bots, both of which look like Daleks designed by Tim Cook-era Apple. Slick, bulb-shaped machines, they bristle with cameras, sensors, and lights, and are covered in white plastic. Uber previously tested some Knightscope robots as parking lot guards, like mobile security cameras scanning for people and reading license plates. Now, Knightscope is dreaming bigger, and looking for investors online.
