As part of our Bionic Learning Network, we have been dealing with the fascination of flying for over 15 years. Since then, we have researched and technologically implemented numerous, additional flying objects and their natural principles, learning from the biological models. A major challenge here was autonomous swarm behavior. With the BionicBee, for the first time our team has now developed a flying object that can fly in large numbers and completely autonomously in a swarm.
At about 34 grams, a length of 22 centimeters and a wingspan of 24 centimeters, the BionicBee is the smallest flying object of the Bionic Learning Network to date. For the first time, the developers used the methodology of generative design: after a few parameters have been entered, the software finds the optimum structure based on defined design principles in order to use as little material as necessary with the most stable construction possible. This consistent lightweight construction is of elementary importance for good maneuverability and flight duration.
The bee’s body forms the compact housing for the beating wing mechanism, the communication technology as well as the control components for the wing beats and adaptation of the wing geometry. A brushless motor, three servo motors, the battery, the gear unit and various circuit boards are installed in the smallest of spaces. The intelligent interaction between the motors and the mechanical system makes it possible to precisely adjust the frequency of the flapping of the wings for the various maneuvers, for example.
