%&tex This previous chapter described the development and implementation process of the Whiteboard Writer. The following is a brief overview of the produced design, models and prototype. The design is covered with dynamic models and CAD drawing. These dynamic models can be categorized into three different modelling approaches, with different levels of detail: \begin{description} \item{Kinematics:} \begin{itemize} \item Basics model \end{itemize} \item{2D:} \begin{itemize} \item Ideal physics implementation \item DC-motor behavior \item Control loop \item Stepper motor behavior \end{itemize} \item{3D:} \begin{itemize} \item 3D physics implementation \item Marker lifting behavior \end{itemize} \end{description} The CAD drawing was added at the end of the development process. Therefore, the CAD drawing has not been made for the levels of detail prior to the marker lifting behavior. The assembled SCARA prototype is shown in \autoref{fig:scara_pic}. This prototype is able to make complete \autoref{test1}, which is the small rectangle. Furthermore, it was possible to write three characters, which completes \autoref{test_triple_char}.
