Abstract
The framework of this paper is the robotics navigation inside buildings using WiFi signal strength measure. In most cases this navigation is achieved using a Partially Observable Markov Decission Process (POMDP). In the localization phase of this process the WiFi signal strength is used as observation. The localization system works in two stages: map construction and localization stage. In this paper we compare three different methods for obtaining the WiFi map in the construction stage. The methods have been tested in a real environment using two commercial robotic platforms. Some experimental results and the conclusions are presented.
