Abstract

Detta arbete har syftat till att skapa ett digitaliserat hjälpmedel till jägare och skyttar, för att assistera innan avfyrning och ge information kring hårda stötar mot vapnet. Kikarsikten är ömtåliga och om de skadas kan det begränsa precisionen hos siktet. Detta i sin tur begränsar skyttens förmåga att utföra sitt arbete korrekt. För att få en förståelse om de krafter som påverkar ett vapen har rekyl- och kollisionstester genomförts under olika förhållanden. Utifrån värden från dessa tester modifieras mjukvaran för att prototypen skall utföra sina funktioner så effektivt som möjligt. Prototypen som tagits fram i detta arbete är uppbyggd utav tröghetssensorer från Analog Devices som erbjuder funktioner för att mäta vinklingen samt kollisioner på ett skjutvapen. This work has aimed to create a digital aid for hunters and shooters, both to assist before firing and provide information regarding impacts on the rifle. Riflescopes are precise and quite fragile instruments. If these are damaged, the shooter's ability is greatly hindered. The prototype developed is a build of inertial sensors from Analog Devices that offer exceptional functionality to assist the user in the aforementioned weaknesses. Recoil and collision tests are some of the tests performed during this project. The outcome of the tests is to provide a fundamental understanding of the forces that can affect a rifle during different conditions. Based on the data from these tests, the software is modified so the prototype can perform its tasks as efficiently as possible.
