Description
Summary:In Abisko National Park there are a numberof weather stations. To be able toretrieve the data from the nodes in thefuture a Quadrocopter-prototype has beendeveloped during this master thesisproject as a first step. A quadrocopter isa helicopter with four rotors placed in across formation. The quadrocopter cannavigate autonomous between different GPSpositionsthat are updated during flighttrough Xbee-modules. All levels fromsources code, design of the electronics todevelopment of the chassis was performedduring the project. During GPS-navigationthe quadrocopter can achieve a stationaryposition with a mean stationary offset ofless than 0.5 meters even in light winds. I Abisko Nationalpark finns det ett antal väderstationer. För att på sikt kunna läsa av väderdata från dessa har en quadrocopter-prototyp utvecklats i detta examensarbete. En quadrocopter är en helikopter med fyra rotorer placerade i ett kryss. Quadrocoptern kan navigera autonomt mellan olika GPS-positioner som ges trådlöst via Xbee-moduler. Alla nivåer från källkod, design av elektronik till utformning och tillverkning av chassit har gjorts inom detta projekt. Vid GPS-navigering kan quadrocoptern uppnå en stationär position med en medelvärdesavvikelse mindre än 0.5 meter trots lättare vindar.
