The Airport of the future is here. And it doesn't need humans

Imagine landing at a major airport and the only human official you meet on your way through the terminal is a customs officer. Singapore's Changi International Airport, voted the world's best for the past six years by Skytrax, is pursuing that goal of extensive automation with such vigor that it built an entire terminal to help test the airport bots of the future. Here's an idea of what Asia's second-busiest international airport is implementing. As a plane joins the long line to land, it's detected, identified and monitored by an array of cameras and technology that bypass the traditional control tower. Once at the gate, a laser-guided aerobridge positions itself to let passengers disembark, while automated vehicles below unload baggage, dodging others that are delivering robot-packed meals or processing cargo.
