eMotionButterflies is robotic butterfly created by German company called Festo. Such robot is refered to as drone hence this Butterfly is essentially drone. However, unlike the device with four propellers, eMotionButterflies is inspired by the nature. The ablility to fly is realized by the moving of the wings similar to the reall insect. That is really special!
The company Festo use such facilities to demonstrate not only the possibility of miniaturization and lightweight construction, but also the ability of a coordinated robot multi-flying. Infrared camers sense their possition and on the basis of the data the movement of each of the butterflies is controlled.
