基于LPC1768的简单几何地图绘制系统

为实现移动机器人环境探知并直观表现的功能，设计一种以前方180°为范围的简单几何地图绘制系统。该系统采用 lpc1768为核心，下位机部分以小型舵机 MG90S和超声模块 HC-SR04的云台组合为基础，上位机通过CVI 编写的程序对下位机测量的数据进行处理，将其通过上位机界面以二维地图形式直观表现；并通过探测3种障碍地图进行验证。实验结果表明：该系统能准确反映机器人前方的环境信息，适用于移动机器人的实时绘图。

Simple Geometric Map Building System Based on LPC1768

In order to realize the function that mobile robot can detect environment and performance it intuitively, the simple geometric map rendering system in front of the robot around 180 degree has been designed. lpc1768 has been used as the core. The small servo MG90S and the ultrasonic module HC-SR04 have been seen as the base of the machine. By the program written, the PC can process data measured by the machine. And the two-dimensional map of the environment in front of the robot would been displayed through window interface written. Through three types of obstacles’ detection, the experimental result can been verified. It shows that the system can accurately reflect the environmental information in front of the robot, so real-time map building can be done for mobile robot.
