Automatická výměna velkých obrobků u obráběcích center
Pomikálek, Adam ; Pavlík, Jan (referee) ; Blecha, Radim (advisor)
The subject of this bachelor thesis describes an automatic workpiece replacement at the machining centres. The description is divided into three chapters. The first chapter deals with clamping and positioning of the technological pallets and workpieces. The second chapter is focused on determination of position of workpieces and on manipulation between the machine and container with assistance of manipulators. In the third part, the thesis aims on containers of the technological pallets and their use in the process of automatic workpiece replacement.

Design of a mobile projection device supporting the virtual reality environment
Šooš, Marek ; Blecha, Radim (referee) ; Tůma, Zdeněk (advisor)
This work deals with the analysis of the state and development of virtual reality and AR. In this work I described in detail the advantages and disadvantages of individual technologies, history, present state and trends in development these technologies. In addition to modelling components in a virtual environment, the current state of the art allows the assembly or disassembling of individual machinery as well as testing their functionality and mechanical properties, using special goggles and gloves. The basis for creating 3D images are special projectors, in one, two, or quadruple configurations. The aim of this bachelor thesis is to design a modular and flexible box for the projectors. The designed concept allows for different flexible arrangements of one, two or four projectors, while providing us with simple and accurate alignment.

Use of sensors in automation
Kiza, Jakub ; Huzlík, Rostislav (referee) ; Blecha, Radim (advisor)
This bachelor thesis contains a summary and conclusion of technical conditions of industrial sensors in the automatization field. The objective of this thesis is to analyze industrial sensors and subsequently list possibilities of their utilization in the automatization. This analysis was performed based on particular kind of sensors which were divided in accordance to their physical qualities. As a result of acquired research regarding principles and function of these sensors, it is possible to specify the essential advantages and disadvantages of the sensors. This acquired research allows for accurate usage and implementation of sensors in the engineering practice. Therefore, this thesis offers a summary of sensor information which can assist a reader to choose the proper sensor for particular applications.
