] Autonomous helicopter flight is characterised by
] helicopters that can fly without a human pilot or
] guidance from a remote-controlled device. Although many
] teams worldwide have been working on so-called vertical
] take-off, unmanned aerial vehicles (UAVs), the CSIRO
] helicopter is the first to fly completely independent of
] expensive global positioning systems (GPS) guidance.
] Instead it uses its brain to control its balance and
] orientation.
