Object-tracking robot using data combination of ultrasonic sensor and servo motor

Abstract

In this paper, distance values of ultrasonic distance sensor and the rotation angle values of the servo motor are used as a way of tracking the moving object. Depending on the environment, it is needed to track the accurate path or the shortest distance by predicting them. So, to prove that the proposed tracking method which using ultrasonic distance sensor and servo motor as the input element is more accurate and affordable than tracking method using vision and LRF and multiple ultrasonic sensors as the input element, it is experimented to compare two tracking methods. Furthermore it is proved that tracking is more accurate by applying Intermediate filter. © 2014 Springer International Publishing.
