Target user localization for a service robot using wireless LAN

This research proposes a location-based service using wireless lan and innovates by adding a robot as a service agent. The proposed system recognizes the limitation of current location-based systems of only being capable of providing information and media services. By adding a mobile robot, physical services can also be provided by this new system. This research utilizes received signalstrength from multiple wireless lan access points (WLAN APs) for the indoor localization of a Personal Digital Assistant(PDA) user; the determined location is set as the target destination of the service robot which navigates autonomously to find the user.
