Amazon turned its Alexa robot into a Ring security patrol bot

Amazon has announced the Ring Rover Cam, a mobile security camera designed for businesses that can patrol and investigate concerns in large facilities. The device is part of the new Ring Robotics brand and is an upgraded version of the Astro home robot, with features such as 4K resolution, a 360-degree scan, and a built-in siren and flashing red light. The Rover Cam can be dispatched to specific rooms or locations, and can automatically head to areas where other Ring devices have triggered an alarm. It also has a blue ring of light that projects onto ceilings to help locate it in large spaces.
