Title Design and Implementation of Intelligent Vehicle for the Ninth Freescale Cup—Hardware Design of Optical- Guided Vehicle Control System
Abstract
Based on the "Freescale Cup" intelligent car competition,the hardware design of optical-guided vehicle control system with a linear CCD as the core sensor is proposed in this paper, aiming at completing the race as soon as possible. It mainly includes selection of system components needed, schematic designing and PCB drawing,and design of car’s mechanical structure .Taking all cases into account, the hardware system is designed by modules, including power module, motor drive module, speed detection module, servo drive module, blue-tooth communication module, linear CCD module, control module of MCU and human-machine interface module, etc. Finally,the system is assembled, tested and improved. Experimental results show that the designed hardware system of the optical-guided intelligent car can meet the requirements.
