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.

FITkit as Step Motor Controller
Čejka, Štěpán ; Mičulka, Lukáš (referee) ; Strnadel, Josef (advisor)
This work deals with problems related to design and implementation of a stepper motor controller based on the MSP430F2617 microcontroller and the Spartan3 field-programmable gate array available on the FITkit platform. In the work, details related to types, principles, functions and stepper-motor control methods are described in detail. Proposed control units are designed to work in two different ways of control and operating modes of motor. Features of the control units have been tested with the SMR 300-100-RI/24 step motor by the means of a custom-designed pulse generator.

Let the young vote: Potential effects of lowering the voting age on elections in Czechia
Čejka, Štěpán ; Palanský, Miroslav (advisor) ; Mošovský, Jan (referee)
Several countries throughout the world have already adopted a reform that enables younger voters, from 15 or 16 years old, to vote. This thesis examines the potential influence of including such voters in the Czech Republic on recent elections. A key feature of my work is that it combines several methods together to model the voter turnout of this age group. To estimate the potential voter turnout of the 15 to 17-year-old category we use fixed effects estimation, together with the exact numbers of citizens from the 2021 state Census and combine them together with the results of Student election that are held by the People in Need organization. The uniqueness of this thesis is that we model the voter turnout in every of the 76 Districts from the 2012 Region election until the 2021 Chamber of Deputies election. We particularly focus on the 2017 Chamber of Deputies and the 2018 Presidential elections both with very narrow outcomes. Finally, we estimate that the inclusion of the young voters most likely would not alter the results of neither election.
