摘要近几年来，信息技术飞速发展，单片机技术和无线遥控技术的提升促使了遥控小车这一领域也发生了日新月异地变化。不同型号，具有不同作用的遥控小车屡见不鲜。在排爆、核污染等高危险地区进行作业，有人工作业所没有的巨大优势，发挥了极大的作用。具有成本较低，风险小，易于控制等优点，并因为体积较小，可以进入人工不能进入的地方进行作业，比如山洞，地震后的救灾工作等。70322

本设计课题是无线遥控智能小车，主要功能就是通过无线遥控技术对小车的运动方向进行控制。

整个设计被分为遥控器和车体两个部分，遥控器可以对小车进行简单的控制。车体部分有四个模块:单片机模块、电机模块、无线传输和电源。主控部分所用器件的核心是Arduino nano，无线传输模块用的是NRF24L01芯片，小车的电机模块则是用L298N芯片。遥控器由两部分组成，第一部分是无线传输模块，也是NRF24L01，另外一部分是主控芯片Arduino，另加两个摇杆，来控制小车的前进后退和向左向右。

Intelligent wireless remote control car design and production

Abstract

In recent years, the rapid development of information technology to enhance the single-chip technology and wireless remote control technology prompted the remote control car in this area has also undergone changes with each passing day.Different models, remote control car with a different role in common. EOD conducted, high-risk areas of nuclear contamination job, it was the work of the great advantages of the industry does not have to play a great role. Low cost, low risk, easy to control, etc., and because of the smaller size, can not enter into the artificial work places, such as caves, after the earthquake relief work.

The design problem is a wireless remote control of the smart car, the main feature is the wireless remote control technology to control the direction of movement of the trolley.

The whole design is pided into two parts of the body and the remote control, remote control can be simple control of the car. Body portion has four modules: SCM modules, motor modules, wireless transmission and power supply. Master-section core components is Arduino nano, wireless transmission module is NRF24L01 chip, car motor module is used L298N chip. Remote Control consists of two parts, the first part is the wireless transmission module is NRF24L01, the other part is the master chip Arduino, plus two joysticks to control the car forward and back and left to right.
