NASA has created a life-size robot that will protect you unless you say something that hurts its feeling in which case it will eat you. From Rich McCormick at the Verge: “NASA has created a robot for DARPA’s upcoming Robotics Challenge Trials. The Valkyrie is a 6-foot-2-inch humanoid machine with detachable arms, sonar sensors, mounted cameras, and a glowing Tony Stark-esque circle in the middle of its chest. The space agency says it’s mobile and dexterous enough to enter disaster zones to provide search and rescue functions.”
