基于蓝牙遥控的多功能智能小车设计与制作
摘要：无线遥控的机器人小车在危险环境作业、人员搜集等应用中可发挥特殊的
作用。本次毕业设计选择基于蓝牙遥控的多功能智能小车为对象。设计了该系统的硬件电路原理图和PCB图，控制系统以STC12C5A60S2单片机为主控芯片，采用L293D为电机驱动芯片、蓝牙无线遥控模块、红外光电传感器模块、超声波发射与接收模块等构成外围扩展电路。将自制的控制电路、控制程序和四轮小车机械结构相结合，制作多功能机器人小车。实验调试实现了智能小车的蓝牙无线遥控、自动避障、自动循迹、自动测速、自动测距等功能。

Development of a smart remote control vehicle based on blue-tooth
communication
Abstract: Wireless remote control robot car could play a special role in the hazardous
environment operations and search & rescue personnel. A multi-function smart car with bluetooth remote control is selected as my graduation thesis subject. The design of the system hardware circuit schematic and PCB diagram is present in paper. The control system circuit is mainly consist of a STC12C5A60S2 MCU as the main chip, as well as a L293D chip for motor driving, a bluetooth wireless communication module for remote control, a infrared photoelectric sensor module for object detection, a ultrasonic transmitter and receiver module for distance measurement. The smart car is implemented by the combination of the self-control circuit, the control program code and four-wheel car mechanical structure. Experimental tests showed that some functions such as Bluetooth wireless remote control, automatic obstacle avoidance, automatic tracking route, auto-sensing objects and auto-detecting distance were completely achieved in the smart car.
