Bartušek, Jakub ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
This thesis deals with design of mobile robot for movement in dangerous environment. The first part of this thesis pays attention on area of mobile robot construction, different types of suitable sensors, motion planning algorithms and robot control. Second part is about construction and design of the robot. Motion planning algorithms are used for this robot and tested in enviroment.

Probabilistic Localization of Mobile Robot
Kopečný, Tomáš ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
Motion control, navigation and sense of orientation of a mobile robot are tied to development of every mobile robot. This work concerns mainly about robot localization in the sense of orientation in space. Nevertheless, nor other aspects of mobile robotics are being omitted. Therefore, the goal of this work is to get familiar with Monte Carlo localization algorithm and apply this algorithm on a real robot.

Two channel stepper motor controller
Hýbl, Matouš ; Arm, Jakub (referee) ; Žalud, Luděk (advisor)
Cílem této práce je vývoj dvoukanálového kontroléru krokových motorů. V rámci práce je popsán jak vývoj elektroniky, tak vývoj příslušného software. Elektronika kontrolŕu je založena na mikrokontroléru STM32F405 a driverů krokových motorů vyráběných firmou Trinamic. Pro komunikaci s nadřazenými systémy je implementován protokol CANOpen a sběrnice I\textsuperscript{2}C a USB. Elektronika byla navržena v software KiCAD and využívá čtyřvrstvého plošného spoje a moderních výrobních technologií. Co se týká software, byl vyvinut jak firmware pro mikrokontrolér, tak software pro ovládání kontroléru. Obě části software využívají programovacího jazyka Rust, který se zaměřuje na bezpečnost práce s pamětí, rychlost a zero-cost abstrakce. Sekundárním cílem této práce je ukázat, jak lze tento programovací jazyk s výhodou použít pro programování nízkoúrovňového embedded software. Firmware kontroléru implementuje nezávislé řízení pohybu obou os kontroléru a to jak v rychlostním, tak v pozičním režimu a zároveň implementuje bezpečnostní funkce pro případy selhání komunikace. Výsledný kontrolér by měl být použit v rámcí výzkumné skupiny Robotiky a Umělé Inteligence a studenty na Ústavu Automatizace FEKT VUT.

Robotic snake model control
Levek, Martin ; Matoušek, Radomil (referee) ; Hůlka, Tomáš (advisor)
The goal of this work was control of a robotic snake model in an unknown environment with randomly generated obstacles. The robotic snake is made of nine segments. These segments are serially connected with actuators, which are used to change the angle between neighboring segments. Its functionality was tested in a co-simulation between MATLAB Simulink and MSC Adams. The snake’s task was to slither through a gap between two walls and reach the target without a collision. The correlation between the snake’s behavior and the set movement parameters was observed.

SCARA control system
Bittner, Jakub ; Burian, František (referee) ; Benešl, Tomáš (advisor)
This thesis shows the process of restoring a SCARA type robot, which has had its controller destroyed. The signal cables as well as the power ones were rewired so that it would be able to create new control system for robot arm. New control system is created using devices from Beckhoff company. For that identification of motors is required. After that PC control is programmend to control every single axis of manipulator, with this program vizualizations of controll elements are created. In the end linear interpolation of movement between points is implemented.

Control of special purpose machine tool
Plocek, Jaroslav ; Holub, Michal (referee) ; Houška, Pavel (advisor)
The master thesis treats the design of control system of special purpose machine tool. The first part analyzes and compares two possible variants of control system which use either a CNC control system Sinumerik or motion control system Simotion. Only the variant with the Simotion control system is subsequently examined in detail: its hardware configuration, the selection of components and partly also the software solution. The thesis further deals with the safety of the realized control system and of the whole machine. There are described general safety requirements of machinery based on harmonized European standards and their specific application in the design of safety functions and the safety circuits of solved machine tool.

Control of packaging machine using Safety PLC
Žiak, Martin ; Novotný, Radek (referee) ; Štohl, Radek (advisor)
This thesis deals with a technology of continuous packaging machine in the beginning from the point of risk assessment and design of necessary measures to reduce the risk as much as it is possible. Here the HRN method was used to quantify every risk factor. Next part documents the implementation of the safety measures and the realization of the safety circuits by using Simatic S7–1500F safety PLC and Shared device functionality. Safety function which is realized in the Sinamics S120 drive is Safe Stop 1. Next, it describes the drive dimensioning and the principle of the drive control. Simotion PLC is discussed in more details and then is used as a motion control master. An approach to the configuration of camming synchronous operation is dealt with in details. Cam design and their realization is documented, too. The thesis also demonstrates the state manager that was implemented in the user program and which is used according to the concept of OMAC state manager. In the end a simple HMI for packaging machine control is described.

Mobile robot control and guidance using computer vision
Granát, Michal ; Jílek, Tomáš (referee) ; Mišík, Štefan (advisor)
Teória riadenia je aplikovaná takmer všade okolo nás, počnúc reguláciou teploty v našich domoch cez modelovanie správania sa trhu až po riadenie vesmírnych lodí. Dôvod, prečo je tomu tak je, je jej výkonnosť a krása, obe skryté v použitých matematických aparátoch. Kolesové mobilné roboty sú taktiež veľmi rozšírené, hlavne v priemysle, kvôli ich obrovskej nosnosti, ktorá je nevyhnutná. Veľmi presné detekovanie trasy je dôležité kvôli dôslednému riadeniu robota po jeho ceste. Jedna z najjednoduchších možností ako vynačiť trasu je použitie čiary, ktorá má iné optické vlastnosti ako jej podklad. Na detekovanie takto určenej trasy existuje niekoľko metód, ale najvýkonnejšie a najefektívnejšie je použitie kamery s následným digitánym spacovaním obrazu, ktoré je síce náročné na výpočtovú silu, ale je ním možne získať obrovské množstvo dát. Hoci táto metóda môže vyzerať zastaralo (vodiaca čiara) stále sa využíva v niektorých projektoch práve kvôli jej jednoduchosti a nízkej cene. Skutočné použitie kamery pre navigáciu všeobecne (nie pomocou čiary) je dokonca zatiaľ oblasť, ktorá je stále vo vývoji. Cieľom tejto práce je zostaviť malý mobilný robot, vytvoriť matematický model, navrhnúť niekoľko regulátorov a riadiť robot po vyznačenej čiare za použitia camery a počítačového videnia.

Control of two-axis positioning table
Mičulka, Tomáš ; Kroupa, Jiří (referee) ; Houška, Pavel (advisor)
The bachelor thesis deals with design and implementation of software for control of two axis positioning table. Table control is implemeted in PLC with the Beckhoff EL 7642 card for DC motor control. Software is designed in the TwinCat3 enviroment, using TC_MC2 according to the PLCopen standard. The use of camming and gearing methods for central control of two motors is presented too.
