Research And Design Of Smart Car System With Function Of Automatic Obstacle Avoidance And Communication Control Based On Arduino

With the continuous improvement of the field of artificial intelligence,the application of smart car,which becomes more and more widely,not only covers the military,industrial and other industries,but also related to many aspects of life services.For smart cars,the function of obstacle avoidance is the main part of research and design and one of the core technology.Automatic obstacle avoidance function,not only for the safety of smart car driving is of great significance,but also can enhance the efficiency of smart car,which is of great help to the handling of goods,unmanned driving and other functions of the automatic performance of the smart car.At the same time,communication control can greatly simplify the control of smart car.The goal of this paper is to study and design a set of smart car system with function of automatic obstacle avoidance and communication control,which integrates the selection and cooperation of the obstacle avoidance sensor,the choice of the core of the car,the cooperation of the communication interface and the communication computer,the circuit design and so on.After comparison,this paper selected Arduino Uno R3 platform as the core of smart car,which controls the smart car’s obstacle avoidance,travel and other functions.In the communication control,Arduino platform and Android platform are strong coupling and in accordance with the current trend,so the host computer using Android platform for development.In the communication interface,Bluetooth technology has a convenient network,no special communication perspective and direction and other advantages,therefor,communication interface between the smart car and the host computer is selected with Bluetooth technology.After the establishment of the communication,just running APP on the Android platform can control the smart car and drive the module of the smart car.APP on the Android platform mainly complete the Bluetooth communication matching and command sending and other functions.In the selection of obstacle avoidance sensors,the system uses infrared sensors and ultrasonic sensors to achieve the measurement of distance as the smart car travels.And,in the ultrasonic sensor increases the steering gear module,so as to achieve automatic obstacle avoidance function of smart car system more accurate and automatic route selection after automatic obstacle avoidance.After testing,the smart car system can complete the automatic obstacle avoidance,and the communication is stable,the circuit response is timely and accurate and the operation is simple,which is the basis of the optimization of the system.
