User following, ultrasonic sensor, mobile robot


This paper presents a mobile robot system in education for understanding a fusion of ultrasonic sensors. One of the most important characteristics of the ultrasonic sensor has a property of the straight within a constant angle range. In addition, the ultrasonic sensor promptly detects the user with fast operating speed and resists influence of external environment. The mobile robot follows the user quickly despite a simple hardware configuration and algorithm. Extensive simulation presents that the proposed user following mobile robot system can be effectively used for robotics learning.
