Abstract

This paper describes a system for high accuracy measurement of robot axis position using CCD image sensors and a set of laser-beams driven by an additional motor. The system works during normal operation such that the measurements can be used for axis control. The principle is explained on a single flexible link. With the given system of sensors and control, it is possible to realize a robot with high absolute positional accuracy.

用于机器人高精度定位的光学测量系统
本文介绍了一种利用CCD图像传感器和附加电机驱动的一组激光束对机器人轴线位置进行高精度测量的系统。该系统在正常运行期间工作,因此测量结果可用于轴控制。在单个柔性连杆上解释了该原理。在给定的传感器和控制系统下,可以实现具有较高绝对位置精度的机器人。
