研究一种智能扫地机器人。从硬件系统控制模块设计到主要技术调试进行了较详细的阐述。以STM32单片机为控制核心与电机驱动、红外线路径识别模块等相互协调应用。进行电路搭建和程序编写。实现了智能扫地机器人红外线避障和自动扫地功能,其清扫面积能达到约70%,清扫率约60%,很大程度受到自身机械机构的限制,后期将对小车的机械结构进行完善。This paper studies an intelligent sweeping robot.From the hardware system control module design to the main technical debugging are described in detail.stm32 mcu is used as the control core to coordinate with motor drive and infrared path recognition module.Conduct circuit building and programming.The functions of infrared obstacle avoidance and automatic sweeping of intelligent sweeping robot are realized.Its cleaning area can reach about 70%and the cleaning rate is about 60%.Because it is limited by its own mechanical mechanism to a great extent,the mechanical structure of the car will be improved in the later stage.
