Self-flying helicopter gets off ground in Calif
(Agencies)
Updated: 2008-09-16 15:03 STANFORD, California -- A four-foot-long helicopter flew itself over the Stanford University campus on Monday in a test of artificial intelligence that researchers say could be used to scout wildfires or on military missions.
The autonomous helicopter performed flips, rolls, pirouettes, stall-turns, knife-edges, and an inverted hover over a field. The helicopter is equipped with an artificial intelligence system developed by computer scientists at Stanford and taught itself to fly by watching the aerobatics of a radio-controlled helicopter flown by a human. "These helicopters can fly maneuvers at the edge of what a helicopter is capable of," said Adam Coates, a PhD student who worked on the project. The helicopters, which communicate with a ground-based computer that guides it, are still being developed. PhD student Pieter Abbeel said the research group has been contacted by a number of companies interested in surveillance and mapping applications, while scientists saw the mini-helicopters investigating wildfires and looking for land mines. Each helicopter costs approximately $4,000 and is outfitted with an accelerometer, gyroscope and a magnetometer to determine its orientation and acceleration, and a GPS or two ground-based cameras to determine its location. |
