             abstract = "Autonomous dirigibles - aerial robots that are a blimp controlled 
                         by computer based on information gathered by sensors - are a new 
                         and promising research field in Robotics, offering several 
                         possibilities for original research. One of them is the study of 
                         visual navigation for this kind of vehicle, which would fill an 
                         operational gap left by inertial, GPS and other kinds of 
                         well-established dead-reckoning navigation. In this paper, a 
                         simple pose estimation system based on artificial landmarks is 
                         introduced for the accomplishment of that task. The vision system 
                         uses that data to keep the dirigible on a progammed trajectory. 
                         This visual control can be done using both fixed, external cameras 
                         focusing the blimp as well as onboard cameras, thus opening a way 
                         for future research on visual cooperation between aerial and 
                         ground mobile robots. Preliminary experimental results showing the 
                         correct functioning of the system are presented and discussed.",
