If you're flying a robot indoors, chances are it's a quadrocopter. The ability hover and maneuver on a dime is essential to whipping around the confined spaces of a lab. Researchers have figured out a way to overcome such obstacles with a fixed-wing aircraft, using laser range finders, sensors and an Intel Atom processor to churn through all the data. To demonstrate just how accurate the on-board navigation systems are, the team of scientists took the autonomous plane to a parking garage with ceilings just 2.5 meters high. Why is that important? The vehicle has a wingspan of two meters -- leaving little room for error. To see the plane in action, check out the video after the break.
