Automatisk bollskjutare för innebandyträning

Sammanfattning: The purpose of the project is to design, develop and evaluate an automatic ball throwing machine for floorball practice. The functions for the machine are automatic aim, shoot with different speeds, ball passing and chip pass. The machine will also supply floorball balls automatically from a storage. This report covers the design of the storage with automatically provider, build a protective frame, design and programming for the pass and the chip pass and overlook possibility to have an automatic detection for the goal. Similar products already exist in other sports like football, tennis and baseball. For throwing the ball the machine uses 2 motors that rotate two wheels. The distance between the wheels enable the ball too pass through but just by so much so the wheels get in contact with the ball and can accelerate it. The project has been done in the Umeå University’s facilities with access to workshop and school programs and computers. The system is controlled by a Raspberry PI model 3 and the programing is done in Codesys.  The tests that were made achieved the requirements and will be seen as successful. The test and evaluations have also been done in the schools facilities. Ideas and inspirations have come from other similar products for other purposes such as tennis, baseball and football. The tests have been evaluated for possible changes and improvements. The project is a first prototype and its purpose is to find functions and possibilities and not build a product.
