Part of the Spyware glossary:

DelFly is a remotely controlled, camera-equipped, highly maneuverable aerial robot measuring less than 30 centimeters (12 inches) in length. The machine can hover, fly forward at up to 15 meters per second (30 miles per hour) and fly in reverse. Sturdy construction allows Delfly to operate in light winds and endure most accidental encounters with obstructions such as walls and trees.

DelFly weighs a little more than 16 grams (approximately 1/2 ounce) fully equipped. The camera gathers images that are transmitted by radio-frequency ( RF ) wireless at 35 MHz to a ground-based station. An onboard lithium-ion battery allows for flights lasting for up to 15 minutes and provides the power to all hardware including the motor, camera and wireless transceiver . The ground-based station is equipped with image analysis software that provides steering and navigation data based on the input from the camera. This feature makes it possible for the user to "pilot" the DelFly with a minimal learning curve.

DelFly can function as an airborne surveillance system, also called a spycam. It can also serve in more routine applications such as photographing landscapes, urban areas, real estate or wildlife. DelFly was designed and built at the Technical University of Delft in The Netherlands.
