"The night watchman of the future," explains the NY Times' John Markoff, "is 5 feet tall, weighs 300 pounds and looks a lot like R2-D2 – without the whimsy. And will work for $6.25 an hour." California-based Knightscope has developed a mobile robot known as the K5 Autonomous Data Machine as a safety and security tool for corporations, as well as for schools and neighborhoods. "But what is for some a technology-laden route to safer communities and schools," writes Markoff, "is to others an entry point to a post-Orwellian, post-privacy world."
