An NYPD security robot will be patrolling the Times Square subway station

The New York Police Department (NYPD) is implementing a new security measure at the Times Square subway station. It's deploying a security robot to patrol the premises, which authorities say is meant to "keep you safe." We're not talking about a RoboCop-like machine or any human-like biped robot -- the K5, which was made by California-based company Knightscope, looks like a massive version of R2-D2. Albert Fox Cahn, the executive director of privacy rights group Surveillance Technology Oversight Project, has a less flattering description for it, though, and told The New York Times that it's like a "trash can on wheels." K5 weighs 420 pounds and is equipped with four cameras that can record video but not audio.
