论文题目：多功能遥控小车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、自动循迹等功能。关键词:单片机；蓝牙遥控；PWM调速；光电传感器Abstracttherobotwirelessremotecontrolcanplayaspecialroleinthedangerousenvironmentofoperation,personnelcollectionapplication.Thegraduationdesign,selectionofmultifunctionalintelligentvehiclebasedonBluetoothremotecontrolastheobject.ThedesignofhardwarecircuitprinciplediagramandPCBdiagramofthesystem,acontrolsystembasedonSTC12C5A60S2MCUasthemaincontrolchip,usingL293Dasthemotordrivechip,Bluetoothwirelessremotecontrolmodule,theinfraredphotoelectricsensormodule,ultrasonictransmitterandreceivermodulesetc.theperipheralexpansioncircuit.Combiningthecontrolcircuit,thecontrolprogramandmadefourwheelmechanicalstructure,fabricationofmultifunctionalrobot.TheexperimentaldebuggingBluetoothwirelessremotecontrol,smartcarautomaticobstacleavoidance,automatictrackingandotherfunctions.目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc407801862"毕业设计论文PAGEREF_Toc407801862\h3HYPERLINK\l"_Toc407801863"2.1总体方案设计PAGEREF_Toc407801863\h4HYPERLINK\l"_Toc407801864"2.2无线模块设计PAGEREF_Toc407801864\h5HYPERLINK\l"_Toc407801865"2.3显示模块设计PAGEREF_Toc407801865\h6HYPERLINK\l"_Toc407801866"2.4测速模块设计PAGEREF_Toc407801866\h7HYPERLINK\l"_Toc407801867"2.5调速模块设计PAGEREF_Toc407801867\h9HYPERLINK\l"_Toc407801868"2.6循迹模块设计PAGEREF_Toc407801868\h10HYPERLINK\l"_Toc407801869"2.7避障模块设计PAGEREF_Toc407801869\h11HYPERLINK\l"_Toc407801870"3、智能车机结构分析PAGEREF_Toc407801870\h11HYPERLINK\l"_Toc407801871"3.1底板设计PAGEREF_Toc407801871\h12HYPERLINK\l"_Toc407801872"3.2电机与底板的连接支架设计PAGEREF_Toc407801872\h13HYPERLINK\l"_Toc407801873"3.3整体装配图PAGEREF_Toc407801873\h14HYPERLINK\l"_Toc407801874"4、控制系统电路设计PAGEREF_Toc407801874\h15HYPERLINK\l"_Toc407801875"4.1MCU的选型P
