Kinematics of a robotic arm
Hekrle, Vojtěch ; Eryganov, Ivan (referee) ; Vašík, Petr (advisor)
This thesis focuses on problematic with the forward and inverse kinematics of a robotic arm with three, four and five arms. The conformal geometric algebra CGA2 is used to solve this issue. The outcome of the thesis consists of four algorithms for computing the given kinematics in the Python language. Specifically, one algorithm for forward kinematics and the others algorithms for the inverse kinematics of the robot with three, four and five arms.

Robotic manipulator control
Černík, Filip ; Sedlařík, Marek (referee) ; Vyroubal, Petr (advisor)
The work deals with familization of the project called BCN3D-Moveo. What is it and how it works. The project can be divided into three parts: structural, electronic and control part. The construction part includes familiarization with robotic arm structures and obtaining its 3D model for consequential 3D printing and assembly. The electronic part deals with the selection adn connection of the appropriate electronics, for the proper functioning of the robotic arms and. The last control part includes the issue of controlling the entire robotic arm and introduces the control of stepper motors.

Robotic Manipulator Exploiting RC Components and Servos
Liška, Jakub ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
Cieľom tejto diplomovej práce bolo vytvorenie vlatného robotického manipulátoru, s pou-\\žitím RC(diaľkovo ovládaných) komponentov a servomotorov. V rámci riešenia bolo potre-\\bné robotický manipulátor vybaviť senzorikou, ktorá umožnuje detekciu kolízii s okolím a zabezpečuje tak bezpečnosť obsluhy v pracovnom priestore manipulátoru. Robotický manipilátor je taktiež vybavený absolútnimi enkódermi pre snímanie polohy jednotlivých kĺbov, akcelerometrom a senzormi pre meranie záťaží pôsobiacich na jednotlivé kĺby. O pohyb ramena sa starajú štandardné krokové motory. Samotné telo robotického manipulátoru bolo navrhnuté s ohľadom na jednotlivé komponenty a je možné ho vyrobiť pomocou 3D tlače. Súčastou riešenia je aj užívateľské rozhranie, pomocou ktorého je možné robotické rameno ovládať.

Object Detection on Robotic Workplace Using Two Kinects
Dragúň, Peter ; Beran, Jan (referee) ; Rozman, Jaroslav (advisor)
This thesis deals with the use of a multi-depth camera Microsoft Kinect V2 for object pose estimation. The main emphasis is on calibration, including mutual and also calibration of a single camera. Which is critical for correct transformation. The theoretical part thesis describes methods for object detection and their pose estimation in space using the robotic operating system. The practical part thesis describes resolving issues with USB saturation by adding a single board computer based on ARM architecture for secondary Kinect.

Robotic Arm Exploiting RC Components and Servos
Bobčík, Petr ; Kapinus, Michal (referee) ; Zemčík, Pavel (advisor)
Cílem této práce bylo postavit vlastní robotické rameno, s využitím RC komponent, serv a dodat k němu i vlastní uživatelské rozhraní, které umožní jeho řízení. Součástí řešení bylo také opatřit robotické rameno potřebnou senzoriku, která by umožnila jistou míru autonomnosti. Pro mé řešení jsem se rozhodl upravil již existující design robotického ramene, s pěti stupni volnosti, založeném na krokových motorech. Přidal jsem senzory, jako je akcelerometr, enkodér, měřič proudu, laserové měření vzdálenosti a kameru. Na základě těchto senzorů je robotické rameno schopné detekovat náraz, pozici odpojených motorů, uchopení předmětu uchopovacím mechanizmem nebo měřit vzdálenost předmětu v prostoru za účelem inverzní kinematiky. Vytvořil jsem také jednoduché uživatelské rozhraní, které umožňuje tři typy ovládání, jako je ovládání jednotlivých kloubů samostatně, autonomně s využitím kamery nebo ručním napozicováním.

Data Analysis for Predictive Maintenance of a Robotic Arm
Žitný, Roland ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
The Mitsubishi MELFA robotic arms used in modern factories work almost without interruption and produce sensory data about their operation. Various analysis techniques can be applied to such data for predictive maintenance, which provide information on the condition and maintenance needs of such robotic arms. The proposed predictive maintenance process consists of a sensory data acquisition system using the slmpclient and mitsubishi-monitor libraries, an analysis method system with anomaly detection using a convolutional autoencoder, anomaly classification using convolutional neural networks, and data segmentation into segments of individual robot actions using hidden Markov models. Such analysis techniques provide information on the severity, type, and location of emerging faults and abnormalities in behavior, which then determine the time required to perform the required maintenance. This work presents a created chain of predictive maintenance processes, where the obtained findings provide valuable insights into the application of predictive maintenance of Mitsubishi MELFA robotic arms in an industrial environment.

Design of a chess manipulator
Novák, Tomáš ; Parák, Roman (referee) ; Cejpek, Zdeněk (advisor)
The bachelor’s thesis deals with a design and realization of a chess manipulator and its controlling through a graphical user-friendly interface. The theoretical part is divided into two sections, a brief insight into manipulation technique and a more in-depth characteristic of robotic manipulators. The practical part focuses on the chosen chess set and a concept of the robotic manipulator. The following parts then describe the structural units, motor and control units and electronic components. Additionally involves the practical part the design and implementation of the manipulator via the Arduino and the user interface. In the final part is created a functional model and designed possible future improvements and development.

System with Model Servos
Jablonický, Jaroslav ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
This work is focused on exploring how to control modeling servos by computers. It will also serve as an overview or a guide for beginners. The work includes the design of a simple robot, more precisely it is a simple robotic hand, but in particular it contains control designs from different platforms using different means. Finally, there are recommendations for each platform.
