This Drone Acts as Your Tour Guide

Engineers at the Massachusetts Institute of Technology's Senseable City Lab have developed a small drone that can potentially lead you wherever you want to go.

Called Project SkyCall, the drone and its accompanying app provide directions to students and visitors, much like a campus tour guide. The app lets you call a flying robot and request directions, while the drone uses your smartphone's GPS to locate you. After typing in your desired location, the drone buzzes off in that direction, but continues to track you, so that it doesn't fly too far ahead.
