The Delft University of Technology in the Netherlands has created a new gadget, and it is a small one. The team has developed a Micro Air Vehicle (MAV) which they claim is the smallest ornithopter in the world that also has a camera attached.
The tiny aircraft measures only 10 cm from wingtip to wingtip, and it has a range of 50 meters. Power is provided by a 30 mAh lithium polymer battery, and this gives three minutes of stealth flying. Light weight construction techniques involve the use of Mylar foil for the wings and carbon and balsa wood for the vehicle body.
The DelFly Micro is the latest from the University's DelFly project, and it improves on the original 50 cm Delfly and the 28cm DelFly II. The goal of the project is to bring together ideas from different fields while creating a tiny aircraft that is capable of achieving independent unmanned (well, uncontrolled) flight.
