Common question: This is not human-piloted (please see the overview vid). The vehicles/ball are tracked by an overhead motion capture system and controlled by a pair of computers.

Aerodynamic SmartBird flight model – Bird flight deciphered: http://www.festo.com/smartbird_en

Aerodynamisches Flugmodell SmartBird – Vogelflug entschlüsselt: http://www.festo.com/smartbird_de

——————————————————————————–­­————————-

SmartBird is an ultralight but powerful flight model with excellent aerodynamic qualities and extreme agility. With SmartBird, Festo has succeeded in deciphering the flight of birds – one of the oldest dreams of humankind.

This bionic technology-bearer, which is inspired by the herring gull, can start, fly and land autonomously — with no additional drive mechanism. Its wings not only beat up and down, but also twist at specific angles. This is made possible by an active articulated torsional drive unit, which in combination with a complex control system attains an unprecedented level of efficiency in flight operation. Festo has thus succeeded for the first time in creating an energy-efficient technical adaptation of this model from nature.

SmartBird ist ein ultraleichtes, aber leistungsstarkes Flugmodell mit einer hervorragenden Aerodynamik und maximaler Agilität. Mit SmartBird ist es Festo gelungen, einen der ältesten Menschheitsträume zu entschlüsseln: den Vogelflug.

Der von der Silbermöwe inspirierte, bionische Technologieträger kann von selbst starten, fliegen und landen – ohne zusätzlichen Antrieb. Seine Flügel schlagen dabei nicht nur auf und ab, sondern verdrehen sich gezielt. Dies geschieht durch einen aktiven Gelenktorsionsantrieb, der in Verbindung mit einer komplexen Regelung bisher unerreichte Wirkungsgrade im Flugbetrieb realisiert. Damit gelingt Festo erstmals eine energieeffiziente, technische Adaption des natürlichen Vorbilds.

Deb Roy: The birth of a word from TED:[embed_code]

http://www.ted.com MIT researcher Deb Roy wanted to understand how his infant son learned language — so he wired up his house with videocameras to catch every moment (with exceptions) of his son’s life, then parsed 90,000 hours of home video to watch „gaaaa“ slowly turn into „water.“ Astonishing, data-rich research with deep implications for how we learn.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the „Sixth Sense“ wearable tech, and „Lost“ producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts. Closed captions and translated subtitles in a variety of languages are now available on TED.com, at http://www.ted.com/translate.
