Onboard computer for electric scooter
Stříteský, Vladimír ; Burian, František (referee) ; Kříž, Vlastimil (advisor)
The aim of this thesis is clarify construction of onboard computer for electric scooter. There is description of components, from which the electric scooter is built. Within this thesis a computer simulation of accelerating scooter is created. Based on the simulation three possible ways of controlling the electric drive were proposed. Then thesis describe parts from witch control system is composed. Onboard computer and support circuits are described in more detail and explained their functions. Description of the created software is in the final part.

Mobile robot control system
Řezníček, Radek ; Kříž, Vlastimil (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with differential drive wheeled mobile robot which is running under a real-time operating system. Introductory part is focused on theoretical description of robot and its original firmware. Practical part deals with creating software and implementation several methods that allow following the line by robot using reflectance sensor array. Significant part of this thesis is focused on design and implementation of communication protocol, based on IEEE 802.15.4 which provides communication between robot and PC. There is also created a PC application that allows to transmit commands to the robot and display information gained from robot.

Remote controlled wheel robot
Ruhás, Sándor ; Kříž, Vlastimil (referee) ; Florián, Tomáš (advisor)
Tato práce se zabývá návrhem a vytvořením kolového robotu na dálkové ovládání. První část práce obsahuje základní úvod do robotiky. Poté se čtenář seznámí se všemi kroky návrhu, které byly provedeny. Samotná konstrukce je rozdělena do dvou hlavních částí: návrh hardware a software. V kapitole návrhu hardware se čtenář dozví, jaké součástky byly vybrány a proč. Pro vysvětlení funkce součástek, budou uvedeny některé důležité parametry. Protože většina součástek může být nastavena různým způsobem, jsou hlavní nastavení detailně popsána. V dokumentu je také uveden jednoduchý ilustrovaný popis hlavních funkcí obslužného software. Na konci tohoto textu jsou diskutovány dosažené výsledky.

Optimizing the selection of actuators for reconnaissance flying robot
Vítek, Milan ; Gábrlík, Petr (referee) ; Kříž, Vlastimil (advisor)
Purpose of this semestral thesis is to create a set of recommendations for choosing optimal motors, propellers and batteries for multi rotor flying vehicles with respect to flight time and flight dynamics. In this thesis you can find analysis of motor, propeller and battery properties and characteristics and their dependencies. Based on these findings there is a set of rules to choose optimal components and set optimal working point. This thesis also describes the design and implementation of a device used to measure the main characteristics of motors and propellers.

Mobile robot control system
Jiruška, Jiří ; Kříž, Vlastimil (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with wireless mobile robot control. The thesis is divided into two main parts. The first part deals with design and implementation of communication protocol based on IEEE 802.15.4 providing communication between robot and PC. The topic of the second part is mathematical description of DC motor and rpm controller design.

Inertial Navigation Unit
Kulka, Branislav ; Kříž, Vlastimil (referee) ; Šolc, František (advisor)
This thesis is concerned with attitude estimation of small flying robots using low cost, small-sized inertial and magnetic sensors. A quaternion-based extended Kalman filter is used, which adaptively compensates external acceleration. External acceleration is the main source of estimation error. If external acceleration is detected, the accelerometer measurement covariance matrix of the Kalman filter is adjusted. The proposed algorithms are verified through experiments. Selected algorithm is implemented on STM32F4DISCOVERY development board.

Controller for quadrocopter
Tilgner, Martin ; Kříž, Vlastimil (referee) ; Burian, František (advisor)
This thesis deals with design and creation of control board for the type of drone quadrotor. The aim of this work is to design create a control unit capable of drone stabilization and communication with superior system. It is assumed that there will be used open source firmware for quadcopter controlling. The work is divided into five parts. The first one deals with the quadrocopter flight principle and creation simple physical model of the quadrocopter. The second part deals with electrical motors for small flying machines and the suitable operating electronics. The third part deals with sensors necessary for flight stabilization and their selection. The fourth part deals with design and creation of PCB control board for the quadrocopter and the fifth part deals with the operating software.

Quadrotor altitude stabilization
Ligocki, Adam ; Kříž, Vlastimil (referee) ; Gábrlík, Petr (advisor)
The aim of this thesis is to design and implement a vertical stabilization for drone developed at the Department of Control and Instrumentation of the Faculty of Electrical Engineering and Communication. Work gradually deals with summary of already existing solutions of already existing projects, analysis of individual sensors possible to be applied in this project and evaluate their pros and cons for measuring the flight altitude. It also deals with the mathematical apparatus suitable for processing altitude data and the design and implementation of the controller for the movement of the drone in the vertical axis. The conclusion summarizes the results achieved on real hardware.
