The K5 robot, developed by Sunnyvale, Calif.-based Knightscope, is designed to be a surveillance robot for law enforcement, private security firms, schools and anything else looking for an extra set of eyes and ears on the ground. The 5-foot, 300-pound robot can roam autonomously, sending back real time data about an area with technology that does facial recognition, lidar mapping and 360-degree video. CNET's Kara Tsuboi got a closer look at what makes the K5 robot tick.
