Surface Topography Formation And Thermographic Analysis In Laser Polishing Of H13 Tool Steel, Joshua D. Miller

Electronic Thesis and Dissertation Repository

Laser polishing, in its simplest form, is the melting of a small layer of material via laser radiation. This creates a small molten pool which is re-distrusted across the surface, resulting in a much smoother finished surface. Although this process has been around for decades now, there has been a recent insurgence into industrial applications. Despite this, the phenomena that occur during the process are still not fully understood. Therefore, increasing the knowledge surrounding the process would be ideal.

To accomplish this, various input parameters of the process are altered to analyze the effect on the finished polished surface. Through …

Development Of An Autonomous Robotic Mushroom Harvester, Nikita Alexeevich Kuchinskiy

Electronic Thesis and Dissertation Repository

The process of development of a new robot is one of the modern technological arts. This process involves multiple complex steps and recursive approach. In this project, a solution for automatic harvesting of mushrooms is developed. In order to design an effective solution, it is necessary to explore and take into consideration the limitations of grasping very soft and fragile objects (particularly mushrooms). We will elaborate several strategies of picking and analyze each strategy to formulate the design requirements, develop a solution, and finally, evaluate the efficiency of the proposed solution in actual farm conditions for real mushrooms. The mushroom …
