Design of the dilatation pad for linear encoder
Moravanský, Richard ; Hadraba, Petr (referee) ; Štěpánek, Vojtěch (advisor)
The bachelor’s thesis deals with the issue of linear length sensors, their dividing, construction, temperature effects and design of an dilatation pad. The aim of the work is a professional search on the topic of linear length sensors, design of variants of the pad and the associated recommendation for practice. The chapter of current knowledge is dedicated to basic knowledge about position sensors, ie. converter sensor connection types. The following chapter is about the description of the basic parts of linear systems, specifically the method of drive and lead in linear systems. After clarifying the concepts, the chapter of linear length sensors will be explained. The chapter deals in more depth with position measurement in linear systems, photoelectric sensing, and a linear encoder from HEIDENHEIN. As the last part of the theory, the analysis of thermal effects is presented. The practical part describes the design of variants of dilatation pad and assembly of elements that allow expansion, their connection and clamping. In the final part, the best variant and recommendation for practice is suggested.

4K real-time video encoding using NVENC technology
Buchta, Martin ; Přinosil, Jiří (referee) ; Kříž, Petr (advisor)
Diploma thesis is focused on real-time 4K video encoding using NVENC technology. First chapter describes the most used video codecs H.264 and HEVC. There is an explanation of the principle of graphic cards and their programmable units. Analysis of the solution of open source Video Codec SDK is also part of the thesis. The main focus of the thesis is an implementation of an application which can handle 4K video encoding from multiple cameras in real time. Performance and qualitative tests were performed for application. Results of these tests were analyzed and discussed.

Intelligent Programmable Stamp Based on Inkjet Print
Crha, Adam ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This thesis deals with a concept and physical prototype of an intelligent, electronically programmable stamp, based on inkjet print. The stamp is basically a small inkjet printer. The stamp can print a simple custom text and is meant to replace regular office stamps. The benefit of the proposed stamp should include cost reduction and need for multiple stamps. The theoretical concept is followed by a prototype, which is an essential part of this work.

The construction of a mobile robot for monitoring ambient temperatures
Čejka, Štěpán ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This diploma thesis deals with the design and control of the mobile robot with caterpillar tracks on the basis of information obtained via infrared thermocouple. The work includes firmware implementation for robot chassis control and communication with the sensors used. The functionality of the proposed system is demonstrated on a robotic task when the robot is searching the source of excessive heat within his surroundings. The theoretical part deals with the basic description of the common robotic chassis, contactless temperature measurement, further analysis of the components used and their principles. The practical part is devoted to the firmware implementation and detailed description of selected problems. In the end of the thesis there is a summarization of the achievements and the success of the robot while detection of the suspicious objects with high surface temperature.

Electronic Subsystem of a Small Mobile Robot
Podolan, Luděk ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The topic of this bachelor thesis is design and construction of a mobile robot with wheeled differential platform. The main goal was to design, implement and test an electronic sub-system for a small mobile robot. Each chapter firstly deals with theoretical aspects of relevant topics and after that describe the process of construction. The thesis shows various ways of construction of the robot with the process of selection of the optimal one. The main controlling part of the robot is the AVR microcontroller placed on the EvB4.3 development board. A simple menu was created on an LCD display for communication between the user and the robot. Battery management is controlled by an analogue to digital converter. The last two chapters focus on encoders and communication between the robot and a proximity sensor. Pictures of the robot are enclosed at the end of the thesis.
