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 signal strength 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.
