Hi friends
How are you???Hope all of u doing well
This is my first posting to our blog ,I am going to give u information about flying of robots.It is invented by our company FESTO,I am very proud to be part of festo family.Recently it was published in MUMBAI MIRROR BUREAU on april 1 2011
German researchers have invented a flying robot that mimics the way birds move during flight. The device is so bird like that it could be mistaken for the real thing from a distance
One of the oldest dreams of mankind is to fly like a bird - to move freely through the air in all dimensions and to take a “bird’s-eye view” of the world from a distance.
No less fascinating is bird flight in itself. Birds achieve lift and remain airborne using only the muscle power of their wings, with which they generate the necessary thrust to overcome the air resistance and set their bodies in motion - without any rotating “components”.

Nature has ingeniously achieved the functional integration of lift and propulsion. Birds measure, control and regulate their motion through the air continuously and fully autonomously in order merely to survive. For this purpose they use their sense organs. Not a bird brain The SmartBird, inspired by the herring gull,is an ultralight but powerful flight model with excellent aerodynamic qualities and extreme agility. The can even start, fly and land autonomously - with no additional drive mechanism making it energy efficient. Its wings can not only beat up and down, but also twist at specific angles. The engineers at Festo’s Bionic Learning Network who developed the Smartbird were facinated by the idea of building an artificial bird that could take off, fly and land by means of flapping wings alone. Flapping is not easy Flapping-wing flight comprises two principal movements. First, the wings beat up and down creating lift. Second, the wing twists in such a way that its leading edge is directed 
The tail of SmartBird also produces lift; it functions as both a pitch elevator and a rudder. When the bird flies in a straight line, the V-position of its two flapping wings stabilises it in a similar way to a conventional vertical stabiliser of an aircraft. On-board electronics allow precise and efficient control of the wing position. For this purpose, a powerful microcontroller calculates the optimal setting for the motors, which adjust the torsion of each wing. The wing’s position and torsion are monitored by two-way radio communication, by means of which operating data are conveyed such as battery charge, power consumption and input by the pilot. Together with the electronic control system and intelligent monitoring the mechanism to adapt to new situations within a fraction of a second.
