本设计完成了基于AT89c52单片机为核心的智能语音播报机器人的设计,本设计可以通过STC89C52单片机来实现红外避障、光电循迹、语音播报等功能。本次设计主要由单片机,电动机,红外传感器,语音播报器和电源等模块组成。该设计轻便小巧并且美观,不需要过多的元件,语音模块和电机模块单独供电,避免电路同时发生故障。其中LM393芯片用于调节小车循迹左右转弯时的灵敏度,大大提高了小车对方向的反应速度。
The design completed based on AT89c52 microcontroller as the core of intelligent voice broadcast robot design, the design can STC89C52 microcontroller to achieve infrared obstacle avoidance, photoelectric tracking, voice broadcast and other functions. The design mainly by the microcontroller, motor, infrared sensor, voice announcer and power modules. The design is small and lightweight and does not require excessive components. The voice module and motor module are individually powered to prevent simultaneous circuit failure. Which LM393 chip used to adjust the sensitivity of the car when the turn around the track, greatly improving the reaction speed of the car on the direction.
