Where birds and planes
collide, a winged robot may help
The bird, apparently a female falcon,
wheels into view 100 feet over Edmonton International Airport, flapping her
wings - hunting behaviour. She pursues a flock of starlings, which scatter
into the safety of the woods. The falcon is majestic, graceful and resolute.
She is also a machine - a battery,
sensors, GPS, barometer and flight control computer stuffed into a
falcon-shaped, hand-painted exterior. A human on the ground controls her
wings.
The Robird patrols the skies around the
airport, in Alberta, Canada. Her mission is to mimic falcon behaviour in
order to head off a serious threat to aviation: the bird strike, which
happens when a bird or flock collides with an airplane. The Robird doesn't
actually catch any prey. Its job is to alert birds to the presence of a
predator, herd them away from the airport, and teach them to prefer a less
dangerous neighbourhood.
