Fingerprint Data Collection Using Autonomous Robot Vehice for Indoor Localization System

There is a high interest for indoor localization systems which works without specific infrastructure, since their installation and maintenance cost is minimal and they are available everywhere in shopping malls, public buildings or offices. Using such an indoor localization system we only need a smartphone with the appropriate application. In order the application be able to determine the user’s position it measures some location specific signals, like Wi-Fi, Bluetooth, Earth magnetic field strength and compares this measured value with premeasured field strength map of the building. This field strengths map needs to be created in advance and this is the only time-consuming operation using such an infrastructure less indoor localization system. The location specific field strings data needs to be measured with the appropriate spacing all along the future navigation routes. This measurement activity can be automatized using an appropriate robotic vehicle. The basic requirements and the development of such a robot is discussed in this article.
