Get ready for some friendly robots in your airport. LG made two different ones -- one is the Airport Guide Robot while the other is a Cleaning Robot. The Airport Guide robot, well, guides you through the airport. Simply feed it your boarding pass and it will tell you how to get to your gate and when your flight is going to take off. It can also respond to your voice, tell you the weather of your destination, and offer directions in one of four languages: English, Mandarin Chinese, Japanese and Korean. Oh, and there's a giant display where it shows you where to go. It can even walk you to your gate, if you prefer.
