  1. 1. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kyle William Coble; [2023]
    Keywords : Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Abstract : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. READ MORE

  3. 2. Range-based Wireless Sensor Network Localization for Planetary Rovers

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : August Svensson; [2020]
    Keywords : SLAM; Sensor Networks; Interplanetary Rovers; Space Exploration; Simulation;

    Abstract : Obstacles faced in planetary surface exploration require innovation in many areas, primarily that of robotics. To be able to study interesting areas that are by current means hard to reach, such as steep slopes, ravines, caves andlava tubes, the surface vehicles of today need to be modified or augmented.

  4. 3. Planetary Rover Wheel and Lower Leg Structural Design to Reduce Rock Entanglements

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Natalie Lawton; [2020]
    Keywords : Mars; rover; wheels; planetary rover wheels; flexible wheels; rigid wheels;

    Abstract : This thesis looks at the SherpaTT planetary rover. The rover is a hybrid walking and driving rover that has been developed and built by DFKI and has already been deployed on several Mars analogue field studies. The SherpaTT rover wheels were found to become entangled in rocks during the last field deployment in Morocco. READ MORE

  5. 4. Compact 3D Microscopy for Planetary Exploration

    University essay from KTH/Rymdteknik

    Author : Gustav Pettersson; [2018]
    Keywords : ;

    Abstract : We propose using grain-of-sand-scale microscopy (1-micrometre resolution) to study the microstructure and composition of planetary material in a fast, in-situ, solid-state device. We have constructed a small and light prototype instrument (100 grams, 0. READ MORE

  6. 5. Wheel-terrain contact angle estimation for planetary exploration rovers

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Ria Vijayan; [2018]
    Keywords : Contact angle; Side slip angle; Nonlinear Kalman filter; Differential Kinematics; ExoMars BB2; Planetary exploration rovers;

    Abstract : During space missions, real time tele-operation of a rover is not practical because of significant signal latencies associated with inter planetary distances, making some degree of autonomy in rover control desirable. One of the challenges to achieving autonomy is the determination of terrain traversability. READ MORE
