自动跟随智能小车的定位与跟随系统设计

Automatic tracking smart car positioning and tracking systemdesignABSTRACTWith the coming of 5g era,the network communication technology has made greaterprogress than that of the 20th century.With the tide of global intelligence,modern society isgradually developing towards an intelligent society.The popularization of artificialintelligence makes people's life more and more intelligent.MCU is increasingly used inPeople's Daily life.In college students'extracurricular science and technology activities,automatic tracking car,automatic obstacle avoidance car and other kinds of smart car is anindispensable role for students to contact MCU programming.So far,most cars have onlyrealized the basic function of following the established route or controlling the driving byhand,but not the following function.The intelligent following luggage used forcommercialization has the disadvantage of high cost and is difficult to be popularized to thepublic.In this paper,the obstacle avoidance system and the positioning and following systemare designed by studying the working process of automatic following smart car,so as torealize the low cost of automatic following.The core control chip of the obstacle avoidancesystem is STM32.The car uses an infrared distance sensor to find obstacles ahead duringdriving.The positioning and following module uses STM32 MCU and Bluetooth module toestablish the connection between the car and the followed object.Key words:Intelligent;Sensor;STM32;Wireless communication
