Vývoj embedded modulu pro podporu lokalizace průzkumného vozidla

Abstract

This thesis deals with the extension of an existing autonomous mobile exploration vehicle for locating in the interior. The vehicle is equipped with a GPS module for location, but in areas with high density in the building interior a location using GPS is practically useless due to insufficient signal. The solution for these sites is offering in use of existing WiFi infrastructure. The coverage is already sufficient in many buildings for a relatively precise location and can be expected, that the situation will improve. The result of this work is software for vehicle control unit i.MX31, communicates with the WiFi module and evaluates the position of the vehicle based on maps and signal strengths of visible APs. In addition, a number of other applications have been created, especially localization software for Windows Mobile and application for measuring serial port quality of connection.
