  1. 1. An Investigation of How Hydrophobicity, Water, and Surface Topography Influence Macroscopic Particle Accumulation on Surfaces : A Case Study of Grass Accumulation on Robotic Lawn Mower

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Rasmus Brask-Nilsen; Petter Ydrestrand; [2023]
    Keywords : Macroscopic Particles; Accumulation; Hydrophobicity; Humidity; Topology; Adhesion; Experiments; Design of Experiments; Grass; Robotic Lawn Mower;

    Abstract : This master's thesis project investigates the impact of hydrophobicity and topology on dry and wet macroscopic particle accumulation on surfaces. The report begins by outlining the challenges associated with this phenomenon and the existing theories and methods used to study it, including adhesion, surface engineering, the Lotus effect, and humidity.

  3. 2. Effects of materials and texturing on wettability of ski base

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : ROSHAN SWAR; [2022]
    Keywords : Cross-country skiing; Stone grinding; UHMWPE;

    Abstract : Cross-country skiing has turned into the most highly competitive winter sport, with skiers having the ability to win by merely milliseconds. Every year researchers, ski - technicians, and athletes come together to prepare the ski base surface that gives the best possible results. READ MORE

  4. 3. Effect of the Textured Surface on Friction Coefficient

    University essay from KTH/Industriell produktion

    Author : Miguel Angel Valdivieso Muñoz; [2022]
    Keywords : Surface texture; friction coefficient; pin-on-disk; crosspatched; circumferential; Yttextur; friktionskoefficient; pin-on-disk; korspatchad; periferiell;

    Abstract : Friction continues to be one of the main causes of energy loss in mechanical systems despite the advances in technology. As a result, this not only involves energy overuse but also maintains high levels of CO2 emissions that cannot be assumed if society wishes to shift towards a more sustainable industry. READ MORE

  5. 4. Exploratory study of the interactions between textured alumina coatings and steel

    University essay from KTH/Materialvetenskap

    Author : Jonas Svantesson; [2018]
    Keywords : alpha Al2O3; diffusion couple; chemical wear; crater wear; DICTRA;

    Abstract : The crater wear of alumina coated WC-Co cutting tools is thought to be influenced by the chemical reactions between the coating and the workpiece material. Three different crystal orientations ((001), (012), and (100) of alpha alumina CVD coatings are examined in combination with four workpiece materials of steel to establish what reactions are present, and the extent of diffusion.

  6. 5. Terrain Classification to find Drivable Surfaces using Deep Neural Networks : Semantic segmentation for unstructured roads combined with the use of Gabor filters to determine drivable regions trained on a small dataset

    University essay from KTH/Robotik, perception och lärande, RPL

    Author : Agneev Guin; [2018]
    Keywords : Semantic segmentation; Deep learning; Gabor filters; Drivable surfaces;

    Abstract : Autonomous vehicles face various challenges under difficult terrain conditions such as marginally rural or back-country roads, due to the lack of lane information, road signs or traffic signals. In this thesis, we investigate a novel approach of using Deep Neural Networks (DNNs) to classify off-road surfaces into the types of terrains with the aim of supporting autonomous navigation in unstructured environments.
