调制光寻线系统及其在自动行走机器人中的应用

Light modulation line-tracking system and it's application in a autorunning robot

为了使机器人可以沿着地面上的指示线自动行走 ,研制了一套调制光寻线系统。调制光寻线系统基于主动式光电检测法中的调制光检测原理 ,同时 ,它针对机器人的具体工作环境 ,还采用了多点巡回检测以及同步采样等技术 ,进一步发挥了调制光检测法的优点 ,如抗干扰能力强、作用距离远、适应范围广等 。

A light modulation line tracking system was designed to assist a robot walking along an indicated line on the ground. The system uses routing detection and synchronous sampling technology to enhance the performance of the modulated light detection and to adapt to different environments. The system has many features such as: high anti disturbance ability, long working distance, broad working range, etc. The system provides the control system with reliable position information. The paper gives a brief introduction to the principle of modulated light detection and then demonstrates the system's design and working principles.
