Title  Design and Realization of Smart Car for The Eighth Freescale Cup Smart Car Contest —— Hardware Design of Visual Guidance Intelligent Vehicle Control System                                        

Abstract 

Based on the eighth "Freescale" Smart Car Design Contest, the hardware design of the visual guided vehicle, whose core sensor is the camera, is completed in this paper after analyzing the specific contest rules and requirements. The main design includes the assembling of the racing car model, the installation of the sensor, and the fabrication of circuit boards. During the process of assembling the racing car, we focus on the change of tracks and rules of the competition. The racing car is modified as a whole, and the installation of the camera is optimized and modified. The top-down modular approach is used in designing the controlling circuit board, which includes the power management module, motor drive module, servo module,image processing module, speed measurement module and the auxiliary debugging module. When the design of the hardware finishes, the whole car model is tested. It proves that the performance of the smart car designed by our team is excellent, meeting the requirements of the competition.
