Almost as if on cue, just after we complained about robots of dubious value, we find two toys that we especially like. First was the iPod Transformer. (OK, so it's not a real robot, but we still want one.) Second is the "Plen," a Japanese invention that can actually skate around your desk and even do skateboard tricks on any flat surface, according to Popgadget. And before you choke on the price--$2,000--be sure to check out the YouTube clip. You might just change your mind.
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.
