Most drivers have desired at one time or another to send messages to other drivers with more content than they can manage with hand gestures. And various solutions have been tried. It's probably good that no solution has been overwhelmingly successful, as incidents of road rage could catapult. The latest car-to-car communication solution, called Drivemocion, has an LED module that can show up to five different messages. The messages consist of emoticons such as a smiley face and a frowny face. It can also show text messages, such as "Thanks," "Back off," and "Idiot." The driver gets to pick the message using a wireless controller, a nice little bit of technology that makes the device easy to install.
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.
