User tracking of an educational robot with android operating system based robot platform

Abstract

For an education purpose between an education robot and user, the robot needs to identify the location of the user and follow the user when the user stays or moves. In this work, a distance measurement scheme between a robot and user using ultrasound sensors and RF modules is introduced. Also, algorithms following the moving user with certain distance are addressed and those applications to the developed robot were implemented, showing the results including distance measurement and user-following. The robot control system is totally based on Android system, which makes the robot operation convenient and compact.
