Using Different Types Ultrasonic Range Finders for Environment Recognition and Obstacles Avoidance of Mobile Robot
Wei Luo, Sadao Maekawa · IEEJ Transactions on Electronics Information and Systems · 1996
These days, it has been pointed that ultrasonic range finder is very useful for some purpose in robot navigation. The usages of ultrasonic range finders are, for example, recognition of the type of a crossing, detection the obstacle and avoidance of it and so on.This paper represents some features of an array type and a rotary type ultrasonic range finder for autonomous mobile robot. And by using these ultrasonic sensor systems, we describe a means of recognizing workspace, and avoiding obstacles among others in detail. We have made some experiments with 2 types ultrasonic range finder. Experimental results verify its effectiveness in a mobile robot navigation.
