Robotic table football - position detection of opponent
Otradovský, Radek ; Zuth, Daniel (referee) ; Lang, Stanislav (advisor)
The aim of this thesis is design of the sensing device to detect the positions of the four independent human axes robotic table soccer and create an output program applicable to game strategy. In the introduction is comparison of previously developed solutions. Next part is the comparison and selection of appropriate sensors applicable to the design table. For specific solutions then select a suitable module for integration into the control system and then test the functionality of the system. Implementation part of the proposal includes the design of construction for detection and next includes all necessary upgrades in the construction of the machine ware to commissioning.

Measurements of the object position and velocity by using optical scanners
Uncajtik, Petr ; Říčný, Václav (referee) ; Kratochvíl, Tomáš (advisor)
The objective of Master’s Thesis is to research the utilization of line optical sensors for object location´s and speed measurement in cooperation with PROTOTYPA company. At the beginning of the Thesis there is an explanation of CCD sensor components and photodiods working principals. Further are discussed particular methods of object sensing. There are schematics of different sensor locations and flying object. The other step deals with introduction to the question of ray impact on sensor in the way of using different light sources and optical systems. In the other part of the Thesis are presented two sensors, which have been chosen by PROTOTYPA company workers. Final part of the Thesis deals with description of executed experimental measurement with LCCD 2048S-14 type of sensor. Experiments are aimed for statical and dynamical processes. In statical part was checked displaying of fixed objects on CCD sensor in internal spaces on the assumption that changing of object-lens focalization, object´s high and shape. For the evaluation was used of MATLAB program. Dynamical part of measurement is aimed for moving objects.

Optosensors
Jakoubek, Martin ; Havránek, Zdeněk (referee) ; Bejček, Ludvík (advisor)
Master’s Thesis solves a problem of vehicle detection for a system control of stoplights on crossroads for a long distance. First, there is a resolution how it is possible to detect cars and select from two sensor’s principles; second, chosen specific microwave detector is a result of sensor market research and finally, there is a description and processing of sensor.

Special length sensors
Pavliš, Jakub ; Prostredník, Daniel (referee) ; Jankových, Róbert (advisor)
This bachelor thesis contains a theoretical description of selected length sensors with emphasis on inductive and optical sensors. The main benefit of this thesis is the design and realization of a special inductive sensor with a small pressure force and an optical sensor with a resolution of 2.5 nanometers. In the thesis are analyzed the selected metrological properties of the designed sensors and the formulation of recommendations for their practical use.

Evaluation of load tests of permanent ground anchors instrumented with optical fibres
Chylík, Zdeněk ; Račanský, Václav (referee) ; Chalmovský, Juraj (advisor)
The thesis focuses on evaluation of load tests of permanent ground anchors instrumented with optical fibres. The thesis is divided into six parts. The first patr introduces topic of the thesis and work procedure. The second part contains all the information about the tested ground anchors, the building site, the loading scheme and methods of measuring. In the third part is evaluation of the apparent tendon free lenght and comparison of measurement methods. Fourth part includes evaluation of sheat friction in the free length. The fifth part describes the behaviour of the part, where free length changes to bond length. The sixth section presents an overall results with suggestions for possible continuation.

Revolution counter of high-speed motors
Biječek, Vilém ; Tomíček, Pavel (referee) ; Skácel, Josef (advisor)
This bachelor thesis deals with two issues. Several methods have been explored to measure rotational speed. Primarily the speed of the high-speed shafts. Based on this, it was found that the most suitable method for this experiment is the optical method. The second focus of this work was design and development of the device. A large part is devoted to the selection and application of components, and simulations of circuit connections, which have been successfully tested and implemented. The output is an accurately measured value shown on the display. It also included the design of printed circuit boards, one for analogue information processing and the other for placing the microcontroller with the display.
