红外通信模块进行通信，用遥控按下按键，数码管显示按键的值(The infrared communication module communicates, uses the remote control to press the key, the digital tube displays the keystroke value)

基于c51单片机红外避障模块，多路检测实现精准避障(Based on the c51 MCU infrared obstacle avoidance module, the multipath detection can realize the accurate obstacle avoidance.)
