Logitech makes several iPod/iPhone audio systems, ranging in size and price from about $70 to about $200. The company's Pure-Fi Express Plus rolls in around $100 and it's designed to be a simple, compact, stereo speaker with a built-in clock and alarm that can be used at home or taken on the road, so long as you're willing to splurge on a set of six AA batteries that power the unit when you cut the cord.
Is this a real RoboCop?
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.
