3 AirPenguin – autonomous self-regulating systems with collective behaviour The AirPenguins are also equipped with complex navigation and communication facilities that allow them to explore their “sea of air” on their own initiative, either autonomously or in accordance with fixed rules. The underlying project: A group of three autonomously flying penguins hovers freely through a defined air space that is monitored by invisible ultrasound “transmitting stations”. The penguins can move freely within this space; a microcontroller gives them free will in order to explore it. The microcontroller also controls a total of nine digital actuators for the wings and for the head and tail sections. By means of XBee, based on ZigBee, large volumes of data can be transmitted between the penguins and the transmitting stations by 2.4-GHz band radio. The penguins recognise each other on the basis of their distances to the transmitting stations. The rapid, precise control allows the AirPenguins to fly in a group without colliding, while also mastering height control and positional stability. As an alternative, they can act synchronously as a group. A comprehensive central surveillance system provides security in case of sensor failure and reports low energy supply. Whenever necessary, it prompts the penguins to return to the charging station. Technology-bearers for the automation technology of tomorrow If the 3D Fin Ray®structure of the head and tail sections is transferred to the requirements of automation technology, it can be used for instance in a flexible tripod with a very large scope of operation in comparison with conventional tripods. Fitted with electric drive mechanisms, the BionicTripod from Festo for example makes for precise, rapid movements, just like the AirPenguin. Autonomous, versatile, adaptive self-regulating processes will acquire increasing significance in future for automation in production. The animal kingdom can provide insights here which, when implemented by resourceful engineers, lead to astounding new applications. The ongoing development of sensor and control technology is thus also being promoted along the road to decentralised, autonomously self-controlling and self-organising systems thanks to inspiration from nature. The transfer to automation technology is also to be found by analogy in regulating technology from Festo, for example in the new VPPM and VPWP proportional-pressure regulators for servo-pneumatics.
