Title Design and Implementation of Intelligent Vehicle for the Eighth Freescale Cup—Hardware Design of Optical Guided Vehicle Control System
Abstract
A complete solution of Optical guided intelligent vehicle control system designed for the Eighth Freescale Cup National Undergraduate Smart Car Competition is proposed in this paper. On the basis of the competition rules, the intelligent vehicle needs to walk upright with two wheels on the track. After a specific analysis of the hardware, modularize method is finally put to use in the system, which includes MCU module, power management module, motor drive module, angle sensor module, photoelectric sensor module, speed sensor module, man-machine interface module and wireless communication module. Besides, in order to check the feasibility of the designed system, a set of PCB is designed. Then the functional modules are testified as well as the whole system. The experimental results show that the hardware design meets the requirements of the subject and controls the system well.
