Robotic table football - optimization of image processing of the playing area
Sijková, Simona ; Parák, Roman (referee) ; Lang, Stanislav (advisor)
The aim of this bachelor’s thesis is to optimize image processing of the playing area of B&R’s Automation robotic table soccer using intelligent vision system from Cognex. The introduction is devoted to a research of machine vision systems and vision systems made by Cognex company. It expounds on fundamentals necessary for system running and compares their pros and cons for different applications. Procedures, changes and solutions of problems which lead to final optimization in In-Sight explorer program are shown in the second practical part. In the end of the bachelor thesis, the influence of illumination and the external environment on the ball detection is discussed.

Design of tester of piezoelectric PVDF layers
Sijková, Simona ; Rubeš, Ondřej (referee) ; Hadaš, Zdeněk (advisor)
The diploma thesis deals with a design of a tester device, a selection and verification of a suitable method for comparing the piezoelectric properties of tested PVDF samples. In the introduction, a basic overview of the theory is important to understand the issue and the various branches of use of PVDF in the field of energy harvesting. The tester device includes a unimorph piezoelectric cantilever beam with tip mass, whose properties are described by three models: a model with N degrees of freedom reduced to one degree of freedom (NDOF), a single degree of freedom model (SDOF), both created in Matlab and a model for verifying results in FEM ANSYS Workbench program. The voltage time response and the voltage frequency response of the models is compared with each other. For two different PVDF samples, the voltage response to harmonic excitation is measured using a tester device, and the piezoelectric properties of one of them are determined using the NDOF and SDOF models.
