This thesis will cover the entirety of the development process of Skara Skyddsängels virtual reality test platform. The platform means to support their efforts in creating a lighting drone service that assists pedestrians and cyclists in areas lacking proper lighting infrastructure while at the same time promoting sustainable modes of transportation. Unreal Engine 4 was used since it provides all the tools needed in order to create the desired product. All changeable parameters requested by the supervisor are fully implemented, such as drone altitude, light angle, and light intensity. Beyond the required parameters, some additional miscellaneous features, such as ambient sound, are also implemented to increase the immersion further. The result is a functioning test platform with an environment resembling a rural road in Skara that can assist the Skara Skyddsängel project in accelerating its testing. / Denna kandidatrapport handlar om den kompletta utvecklingsprocessen för Skara Skyddsängels virtual reality testplatform. Denna plattform skapas för att assistera Skara Skyddsängel i deras arbete att utveckla och utvärdera belysningsdrönare för fotgängare och cyklister i områden där traditionell belysningsinfrastruktur inte är lönsam. Genom att erbjuda alternativ infrastuktur strävar projektet mot en ökad användning av mer miljövänliga transportmedel. Samtliga av projektledarens krav är implementerade, såsom till exempel drönarhöjd, ljusvinkel och ljusintensitet. Dessutom finns några övriga funktioner implementerade, så som ljud från omgivningen för att göra miljön mer verklighetstrogen. Den slutgiltliga produkten är en fungerade testplatform med en miljö som efterliknar en väg på landsbygden utanför Skara. Denna plattform kommer hjälpa Skara Skyddsängel i att göra tester för att hitta optimala drönarinställningar / Skara Skyddsängel

Through the electrification of bicycles, the implementation of new active and passive safety systems becomes possible. Examples for such systems are bicycle ABS, TU Delft - Fall Prevention Bicycle, Bosch Help Connect (eCall System for bicycles), airbag helmets and many others. One of the main difficulties in developing and testing such safety systems is, that test riders should not be exposed to high risks when testing early prototypes. Thus, an automated or remote-controlled test platform for the analysis of bicycle dynamics and for testing of newly developed safety systems could boost the development of such systems and make it safer. The main difficulty when developing such a test platform, which has been addressed in this work, is stabilizing it at low speeds (1.5 m/s - 4.5 m/s) and being capable of tracking a desired yaw rate, only using a steer actuator. In the following, the development of such a test platform is described and first experimental results are presented.
