Design of a three-axis manipulator
Vojtěch, Michael ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
The goal of master’s thesis is design of a three-axis manipulator working as x-ray unit. Axis include one rotary and two liner. The work is based on the existing manipulator and the goals are reducing vertical installation space, weight reduction, increasing accuracy and repeatability. Creating 3D model with computational report from available components. There is resulting variant solved with linear motor in this thesis with that there is indicated alternative variant but not dealt with in detail.

Electromagnetic pulse accelerator of projectiles
Žamberský, Jan ; Jirák, Josef (referee) ; Frk, Martin (advisor)
Tato práce se zabývá použitím magnetického pole k urychlení projektilů v zařízení zvaném coilgun. Je složena ze dvou částí, z nichž první je teoretická diskuze o magnetismu a jeho využití, druhá část je o vlastním coilgunu, jeho výhodách a nevýhodách. Následuje série měření na dvou experimentálně postavených coilgunech a jejich optimalizace pro dosažení co nejlepších výsledků. První část probírá více témat. Na začátku je krátká kapitola, ve které se definuje magnetické pole a s ním související konstanty a jevy. Další dvě kapitoly jsou zaměřeny na různé typy materiálů, především feromagnetik, jak reagují na přítomnost magnetického pole a jakými parametry jsou specifikovány. Dále je výčet některých aplikací magnetizmu napříč lidskou společností. V druhé části se popíše princip coilunu a jak byly prototypy vyrobeny. Měření na prvním prototypu je zaměřeno na testování různých materiálů projektilu, jeho rozměrů a přínosy externího magnetického obvodu okolo cívky. Taktéž je tam kapitola pojednávající o způsobu měření rychlosti projektilu. Druhý prototyp se snaží eliminovat nedostatky zjištěné na prvním a prozkoumat výhody vícenásobného urychlení na dalších stupních.

Robotic table football - game strategy
Parák, Roman ; Matoušek, Radomil (referee) ; Lang, Stanislav (advisor)
The aim of the master's thesis is the robotic table football device modification and the design of game strategies. The thesis was extended by the design of technology for the robotic table football safety and the design of the Human Machine Interface (HMI). In the introduction so far developed solutions and presentation of the B&R Automation company are described. The following chapters describe mechanical solution modification, electrical wiring diagram design, creating simulation in the MATLAB development environment, resolving security issues and the subsequent application of a solution into the robotic table football. The conclusion of the thesis is devoted to the visualization interface design.

Linear drive control based on object motion detection
Novotná, Eliška ; Harabiš, Vratislav (referee) ; Sekora, Jiří (advisor)
The diploma thesis deals with motion detection and linear drive control. The diploma thesis is divided into a theoretical part, where the part of ultrasonic sensors and linear actuators, including the types of individual linear actuators, is mainly described and explained. The practical part presents the solution itself, both in terms of hardware and software. This part therefore contains the system design together with the flowcharts and the simplified 3D design of the structure. At the end of the work is given a sample of the final structure.

Position control of cross-table dedicated manufacturing machine
Plocek, Jaroslav ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis treats the drive solution of the two axis cross-table of a single-purpose manufacturing machine. The first chapter analyzes the concept of drives and compares different variants using either a direct linear drive or a ball screw with a rotary servo drive. The thesis further deals with sizing the motor and the power unit assembly and the description of the whole measuring system. The structure of cascading position controller, its description and the calculation of current and speed control loops is covered in the next part. The last section discusses practical settings of all control parameters.

Design of linear axis for heavy machine tool
Göbel, Lukáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The content of this thesis is the description the various component of the linear feed axis, which are used in heavy duty machine tools. This describes their features, advantages and disadvantages and on these basics, are selected different appropriate design variants. In the second part of this thesis has been drawn up constructional design of these variants. They were subsequently compared and then was chosen the most ideal one for the designed machine, which is heavy machine tool upper gantry type. The work also includes the 3D CAD model of the final version and drawing documentation.

Control of the Electromechanical System with a Linear Motor
Judinyová, Katarína ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
The submitted Master’s thesis deals with the general principle of the electric drives’ functioning and with the construction of a synchronous electric motor. A comparison of a linear drive and a rotary drive with rack and pinion system is provided, as well as an overview of common type linear drives. A mathematical model of a rotary synchronous motor, the Clark’s and Park’s transformation and the principle of vector control is explained. A method of the linear parameters’ conversion to the rotary equivalents is demonstrated. A block diagram to motor control is designed. The control quality is tested by various criteria. Lastly, there is a simulation provided on how the changes of motor’s parameters affect the control quality.
