Submission + - Drone Dragonfly takes to the air. (suasnews.com)

garymortimer writes: "These people from Festo are really beyond clever.

The mechanics of dragonfly flight are unique: dragonflies can manoeuvre in all directions, glide without having to beat their wings and hover in the air. Their ability to move their two pairs of wings independently enables them to slow down and turn abruptly, to accelerate swiftly and even to fly backwards.

A natural model for flight

With the BionicOpter, Festo has applied these highly complex characteristics to an ultra-lightweight flying object at a technical level. For the first time, there is a model that can master more flight conditions than a helicopter, plane and glider combined.

In addition to controlling the flapping frequency and the twisting of the individual wings, each of the four wings features an amplitude controller. This means that the direction of thrust and the intensity of thrust for all four wings can be adjusted individually, thus enabling the remote-controlled dragonfly to move in almost any orientation in space. The intelligent kinematics correct any vibrations during flight and ensure flight stability both indoors and outdoors."

Submission + - SmartBird stunning flapping drone from Festo (suasnews.com)

garymortimer writes: "Another beautiful bit of work from Festo biomimicry is something we are going to see lots of in the future. This has really brightened my Friday up! It looks right it flies right and guess what its more efficient because of it.

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. 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, whichin conjunction with a complex control system makes for unprece -dented efficiency in flight operation"
