The DelFly project〔http://www.delfly.nl/〕 focuses on fully functioning systems and follows a top-down approach toward ever smaller and more autonomous flapping wing MAVs. The DelFly Micro with its 10 cm wing span and 3.07 grams is still the smallest untethered, free flying, fully controllable (thrust, elevator, rudder) flapping wing MAV equipped with a camera and video transmitter carrying its own energy source.〔http://www.guinnessworldrecords.com/records-7000/smallest-camera-plane/〕 A hobbyist from Albany NY, build an even smaller version of 920 mg and just 60mm wing span, which is (the worlds smallest free flying flapper till date ). The 28 centimeter 16 gram DelFly II performed ground-breaking work in the area of autonomous flight, mainly using off-board processing.〔〔〔http://www.lr.tudelft.nl/en/cooperation/facilities/mav-laboratory/publications/〕 The DelFly Explorer is the latest development. It measures 28 centimeter while weighing 20 grams. It is equipped with a miniature stereo vision system enabling fully autonomous flight in unknown environments. ==History== The DelFly project started in 2005 as a Design Synthesis Exercise for a group of Bachelor of Science students at the Faculty of Aerospace Engineering of the TU Delft. The flapping wing design was mentored by (Wageningen University ),〔 the remote control and micro camera integration by (Ruijsink Dynamic Engineering ), and the real-time image processing by the TU Delft.〔De Wagter, Christophe, and J. A. Mulder. "Towards vision-based uav situation awareness." AIAA Guidance, Navigation, and Control Conference and Exhibit. 2005.〕 The result of this exercise was the ''DelFly I'', a 50 cm wingspan, 21 grams flapping wing MAV equipped with a camera. The DelFly I was able to fly but could not hover, and there was considerable motion perturbing the camera images. In 2007, the DelFly II was created: a 28 cm wing span 16 gram flapping wing MAV equipped with onboard camera. This version was not only smaller, but it had a much broader flight envelope ranging from 7 m/s forward flight to hover and even backward flight at -1 m/s. The flight time of the DelFly II was around 15 minutes. The DelFly II was followed in 2008 by the DelFly Micro, a 10 cm wing span, 3.07 gram flapping wing MAV, also equipped with camera.〔("Delfly Micro IEEE Article" )〕 The DelFly Micro is fully steerable with 3 controls for the throttle, elevator and rudder. Given the limited onboard energy, the flight time of the DelFly Micro was around 2 to 3 minutes. The DelFly Micro featured in the Guinness book of records 2009 as the smallest airplane in the world equipped with a camera. The DelFly participated in the 2005, 2007, 2008, 2010 and 2013 editions of the Micro Air Vehicle Competitions and was the first vehicle to demonstrate fully autonomous indoor flight.〔http://www.imavs.org〕 The DelFly Explorer was created in 2013. It has a stereo vision system that allows autonomous obstacle avoidance even in unknown and unprepared environments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DelFly」の詳細全文を読む スポンサード リンク
