Ferienakademie is a voluntary holiday academy organized by three Universities from southern Germany: Freie Friedrich-Alexander University of Erlangen-Nürnberg (FAU), Technical University of Munich (TUM) and University of Stuttgart. It takes place in Sarntal, which is a beautiful high valley near to Bozen in Italy. This year I participated in Bernd Brügge’s and Daniel Siewiorek’s course “Cyber Physical Systems”. We built a system which can help workers in extreme environments to minimize risks and to identify hazards earlier. Our system creates a local peer-to-peer mesh-network which ca transfer sensor data from so-called “emergency beacons”. These beacons can be deployed by specially-equiped workers, or from a drone. This can help to collect important environmental data in hazardous environments. Sensors can measure radioactivity, heat, oxygen levels and other essential values. The autonomous drone is[…]
