With a wingspan of 70 cm and a body length of 48 cm, the model dragonfly weighs just 175 grams. The wings consist of a carbonfibre frame and a thin foil covering. The structure is made of flexible polyamide and terpolymer. The small ribcage houses the battery, nine servo motors and a high-performance ARM microcontroller, all installed in the smallest of spaces just like the sensors and wireless modules.
Up and down, forwards, backwards and to the side: the flapping wing design of the BionicOpter enables it to fly in all directions in space and hover in mid-air just like a helicopter. Unlike a helicopter, however, the dragonfly does not need to tilt forwards to generate forward thrust. This means that it can fly horizontally as well as float like a glider. Its lightweight design means it is able to start autonomously.
