摘要
介绍了用于教学用机器人避障功能的超声波测距系统的构成及原理,该系统在教学用机器人避障功能的应用中,测距的范围为0.2～5.0m,精度为±4cm。
An ultrasonic detecting distance system is designed for a mobile robot to avoid to obstacle in this paper.The software and hardware design of the system based on single chip microcumputer AT89C51 are discussed in detal,and the structure and principle of the system are also presented.The scheme has been applied to the obstacle avoidance of a mobile robot.The results show that it is well able to satisf the demand,and the range of measure is from 20centime- ters to 5meters,the precision is±4centimeters.
