Built with artificial intelligence, the Hover Camera Passport selfie drone detects and follows users. Source: Zero Zero Robotics At this year's CES, a little company named Zero Zero Robotics demonstrated a flying camera drone that hovers near you taking pictures and autonomously detects, follows and records your movements. That selfie drone, called Hover Camera Passport, is now available and just picked up a huge backer in the form of Apple Inc. The smartphone giant has started exclusively selling the drone online and in its Apple stores in five countries. The Hover Camera Passport is powered by internally-developed artificial intelligence that the company says allows consumers to operate the drone camera out of the box and works for both indoor and outdoor environments.
