红外线避障检测程序，2路，后来改成了6路的，但是因为公司电脑上只有2路的，所以只能发这个了，以后我会把6路的也传上来。 atmega8单片机，winavr编译.-infrared obstacle avoidance detection procedures, two road, and later changed six road, but because the company has only two computers on the road. So this can only be released in the future I will have the six-way onto. Atmega8 microcontroller, winavr compiler.
