Radio Controlled cars are often used as scaled vehicles in various research studies, yet they have not been analyzed exhaustively based on their own unique dynamics. This is especially important since scaled vehicles can outperform their full sized counterparts relative to their sizes. In this study we present an experimentally validated dynamic model using mathematical analysis, simulation, and experimental validation. To model the lateral dynamics of the vehicle, a 3-DOF dynamic bicycle model is used. The model simulation will be constructed in Simulink using the equations of motion produced by the mathematical models. The experimental validation is conducted on a Traxxas XO-1 which is capable of achieving speeds in excess of 100mph. The platform is instrumented with inertial sensors, time-of-flight sensors and an optic flow sensor to measure the states and inputs of the vehicle.
