For mobile robots which operate in human environments it is not sufficient to simply travel to their target destination as quickly as possible. Instead, mobile robots in human environments need to travel to their destination safely,  keeping a comfortable distance to humans and not colliding with any obstacles along the way. As the number of possible human-robot interactions is very large, defining a rule-based navigation approach is difficult in such highly dynamic environments. Current approac...

The thesis addresses the vast problem of mobile robot localization in the dynamic environment of a robotic contest. Method based on particle filters is developed, using only the image of a catadioptric visual sensor as its input. The advantage of this approach is an easy portability thanks to independence on other systems of the mobile robot and robustness to external influences such as robot collisions. This new method employs the composition of fast color thresholding, look-up coordinate trans...

The stand-alone Global Positioning System (GPS) or an Integrated GPS and Dead Reckoning Systems (such as Inertial Navigation System or Odometer and magnetometer) have been widely used for vehicle navigation. An essential process in such an application is to map match the position obtained from GPS (or/and other sensors) on a digital road network map. GPS positioning is relatively accurate in open sky conditions, but its position is not accurate in dense urban canyon conditions where GPS is affec...

In 1999 Europe, through the European Commission and the European Space Agency, began detailed definition of a second generation Global Navigation Satellite System (GNSS). This GNSS development programme, known as “Galileo”, was intended to both complement and compete against the existing US Global Positioning System (GPS). Unlike GPS, Galileo is intended to be privately financed, following the initial development investment from the EC and ESA, which implies that Galileo should provide some reve...

Utilizing a Global Navigation Satellite System (GNSS) together with an Inertial Navigation System (INS) is today a common integration method to obtain a positioning solution for autonomous systems. Both GNSS and INS have benefits and weaknesses where the best parts from both systems can be combined with a Kalman filter. Because of this complementary nature, it is of interest to look at the robustness of the positioning solution when the Global Navigation Satellite System is temporarily not avail...

Les mammifères ont la capacité de suivre différents comportements de navigation, définis comme des " stratégies " ne faisant pas forcément appel à des processus conscients, suivant la tâche spécifique qu'ils ont à résoudre. Dans certains cas où un indice visuel indique le but, ils peuvent suivre une simple stratégie stimulus-réponse (S-R). À l'opposé, d'autres tâches nécessitent que l'animal mette en oeuvre une stratégie plus complexe basée sur l'élaboration d'une certaine représentation de l'es...

Avec la demande croissante d'espace urbain, de plus en plus de parkings à plusieurs étages sont nécessaires. Bien que ces parkings contribuent à une utilisation plus efficace de l'espace urbain, ils introduisent également un nouveau problème. Les rapports suggèrent environ 70 millions d'heures de recherche d'emplacements de stationnement chaque année, soit une perte équivalente de 700 millions d'euros pour la seule France. En outre, les utilisations des parkings vont au-delà de leurs objectifs i...

The field of 3-D-environment reconstruction has been subject to various research activities in recent years. The applications for mobile robots are manifold. First, for navigation tasks (especially SLAM), the perception of 3-D-obstacles has many advantages over navigation in 2-D-maps, as it is commonly done. Objects that are located hanging above the ground can be recognized and furthermore, the robots gain a lot more information about its operation area what makes localization easier. Second, i...

The hippocampal-medial prefrontal circuit has been shown to serve a critical role in decision making and goal directed actions. While the hippocampus (HF) exerts a direct influence on the medial prefrontal cortex (mPFC), there are no direct return projections from the mPFC to the HF. The nucleus reuniens (RE) of the midline thalamus is strongly reciprocally connected with the HF and mPFC and represents the major link between these structures. We investigated the role of RE in functions associate...
