The aim of this master's thesis is to design a remote-controlled platform for testing advanced assistance systems in modern cars. The work focuses on the detailed construction of a robust undercarriage powered by electric motors. This undercarriage must be capable of carrying various dummies, such as a pedestrian, child, or cyclist, and withstand being overrun by a vehicle, which is verified using the finite element method. The thesis also includes the development of a specialized attachment system for dummies that minimizes potential damage to the tested vehicle. The result is a complete design of the platform, including a detailed description of the selection and integration of electronic components, providing a comprehensive basis for th...
