2、两轮各用一个电机执行，用MAX232芯片来控制，前方和底部探头采用红 外发射管和红外接收管进行障碍物检测以及地面信息的采集。 关键词：关键词：AT89S52，寻线，避障，避悬崖，流水灯 3 Abstract based on undergraduate electronic contest in recent years, the research on this car according to the application of the embedded system, puts forward presented a 8-bit microcontroller as the syste
3、m can realize intelligent follow line brain obstacle-avoidance avoid cliff car design methods, through the main chip 32 completely to these ports, IO port to signal input circuit, control circuit and execute circuit, and make use of infrared sensor technology testing obstacles and ground information
4、, collected by AT89S51 for timing control, intelligent obstacle-avoidance and resolutely line from the cliff. Intelligent car using two rounds of the front wheel drive, with a motor with MAX232 chips to carry out, control, and front and bottom probe USES the infrared tubes and infrared receiving tube obstacle detection and ground information collection. Key words: AT89S51 , Cast about line，obstacle-avoidance avoid cliffs， flowing water line of light. 4 目 录 摘要 2 Abstract 3 1 引言
