This is part 2 of 3 videos from the hovercraft design competition at the University of Maryland, Colllege Park. Part of ENES 100 program. The idea was to keep the hovercraft on the black guide line as it moved forward through the channel. There were two tricky turns the vehicles were needed to maneuver. A Lego Mindstorms NXT kit was programmed to control the vehicle. A short extract from Wikipedia - (http://en.wikipedia.org/wiki/Hovercraft) A Hovercraft, or Air-Cushion Vehicle (ACV), is an amphibious vehicle or craft, designed to travel over any sufficiently smooth surface supported by a cushion of slowly moving, high-pressure air, ejected downwards against the surface close below it.Hovercraft have one or more separate engines (some craft, such as the SR-N6, have one engine with a drive split through a gearbox). One engine drives the fan on the bottom of the hovercraft, (the impeller) which is responsible for lifting the vehicle by forcing high pressure air under the craft. The air therefore must exit throughout the "skirt", lifting the craft above the area on which the craft resides. One or more additional engines are used to provide thrust in order to propel the craft in the desired direction (these engines help push the hovercraft). Some hovercraft utilize ducting to allow one engine to perform both tasks by directing some of the air to the skirt, the rest of the air passing out of the back to push the craft forward.
