HOVER CRAFT

摘要

It sounds like something out of a science fiction movie. You're walking along a dark country lane at night. You're a bit unsure where you're going or your surroundings and so you whip out your mobile phone. The screen has its own comforting glow, but you're going to use it for much more than that. A few moments later a drone equipped with high-powered onboard lights appears above your head, hovering and circling. It 'walks' with you, lighting your route, until you reach your destination.
