The RooT is an electric scooter designed to create a new user experience that enhances the advantages of electric mobility: it is quiet, clean and intuitive. It moves with you like a “flying carpet”. In the previous projects, the RooT concept has already been developed until a first prototype. This first prototype was still a very primitive version of what RooT will become. The first prototype only had the function to test the flying carpet experience in a forward acceleration and deceleration. It is not able to steer. The assignment is to develop a prototype that is able to steer. The functioning of the suspension system must be incorporated in the design. The end product must be a fully functioning prototype that is able to do test drives with test persons. The aesthetics are not the main focus for this assignment, but they will also be taken into account. For getting a deeper understanding in some aspects that where important for the new design, some research was made. This can be found in the Analysis part. From every research area, the conclusions will be summarized. The conclusions will eventually lead to the design brief, this is a list of demands and wishes for the new design on which the new prototype should fulfil. With the Design brief as the basis, the first ideas are drawn as a set of possible Solutions. Parts of these Principle Solutions can be documented into a morphological chart. From this chart, all the best combinations of ideas will be brought together into ideas. The best ideas will be developed into concepts. In the embodiment phase, the final concept will be chosen. First all concept series will be modelled with the help of Working model. The chosen concept series can be equipped with multiple types of steering mechanisms. The best steering mechanism will be chosen. With help of the J-Bike6 software, the chosen steering mechanism will be analyzed. With all the test data from Working Model and J-Bike6 in mind, and the latest design features, the final design could be made. The final design was completely done in Solidworks. The last hand drawings and sketches where made right after the working model tests. In this chapter the final design process is reported. After the design was made, construction started. The building process took a few months and is summarized in the chapter Final Testing and Design. In the final part of this chapter also the driving tests of the new build prototype will be discussed. To continue the project after the graduation, some recommendations are written down that can help improving a possible next prototype. Also the references, and additional information that was not present in this thesis can be found with the help of this chapter.
