“Calling from the other room” by Ceiling Ultrasonic Locator and Microphone Array

摘要

This paper describes a mobile robot for home service purpose together with ubiquitous ceiling ultrasonic locator and microphone array. User call can be detected by those ubiquitous devices and then mobile robot navigates toward given location. After reaching to the given location, the robot tries to find out user location by using stereo camera, laser and onbody microphone array. We implemented those system at our experimental house "Rokko Holone". System components and experimental results are shown.
