Automated object tracking using robotic manipulator
Zelený, Miroslav ; Ligocki, Adam (referee) ; Chromý, Adam (advisor)
This diploma thesis deals with the tracking of objects using a robotic manipulator Epson C3 and a color camera. The work describes the basic qualities of the device to be used. The OpenCV library and its wrapper EmguCV are used as software tools for computer vision. It discusses the basic issues and principles of tracking objects in the image and introduces some methods of tracking. These methods have been tested and therefore their strengths and weaknesses, which appeared during testing, are listed here. Furthermore, there is a procedure for calculating the new coordinates of the camera and the manipulator effector using homogeneous transformations. The work contains the results of testing the algorithms and their evaluation. The output of the work is a test application for the Epson C3 robot.

Embedded Device for Robotic Arm Control
Kyzlink, Jiří ; Goldmann, Tomáš (referee) ; Orság, Filip (advisor)
This diploma thesis deals with a design and implementation of an embedded device (module), used to control a robotic manipulator. The module instructs servomotors of the manipulator to move according to the commands received via USB interface. The module consists of two double-sided printed circuit boards. The first one allows connection to the CAN bus, redundant and thus reliable power supply for servomotors as well as the whole module. The second board, compute oriented one, embeds powerful microcontroller used to communicate with the servomotors and to solve the kinematics tasks. As a part of the thesis a graphical user interface as well as a web-oriented interface were developed. Both interfaces allow full control of the manipulator. All the communicating buses, tools and methods used during the design and implementation phases of the work are described in the thesis. Finally, measurements proved improvement of the motion smoothness and response times in several orders of magnitude in comparison to the previous system.

Design of a robot gripper
Stoszek, Šimon ; Hůlka, Tomáš (referee) ; Matoušek, Radomil (advisor)
This bachelor's thesis is focused on robotic end-effectors, grippers in particular and is bringing their general overview. The goal of the thesis is to design, assemble and program a three finger gripper. The effector is designed using ROBOTIS Premium building set, especially Dynamixel actuators, obstacle detector and Bioloid frames, 3D printed parts. It is possible to use this three finger gripper in two configurations: centric for grasping spherical objects and parallel for grasping cylindrical objects. Functionality of this end-effector was successfully experimentally verified. Main benefits of the gripper are: its ability to adapt to shape and size of grasped object and to automatically initiate its grasping.

Robotic Arm with Model Servos
Bobčík, Petr ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
The main goal of this thesis was to create my own robotic manipulator, which is controlled by its own user interface. I made a robotic arm based on computer Raspberry Pi 3B+ with 5 digital servos and a gripping mechanism in the form of a claw, to which I also attached a laser pointer. The user interface problematics was solved by creating a simple web page (combination of HTML, PHP and JS), which i placed into the Apache 2 web server (installed in Raspberry Pi). I successfully incorporated a way to control the servo one by one and how to control the whole arm with inverse kinematics into the user interface.

Implementing the checkers game using a robotic manipulator
Lichosyt, David ; Ligocki, Adam (referee) ; Lázna, Tomáš (advisor)
The thesis starts with a field research about existing robotic systems with implemented checkers or similar desk games. In its next parts are described posibilities of controling robotic manipulator Fanuc LR Mate 200iD 4S using controller R-30iB Mate from platform ROS located on external hardware. In few next pages of the thesis there are mentioned designed and used physical models. Following chapters describe real time game situation detection, game logic implementation and human input with safety in mind. At the end of the thesis there are mentioned rule checking algorithms, system operation instructions and possible future upgrades of the system.

Calibration of Robotic Workspace
Uhlíř, Jan ; Veľas, Martin (referee) ; Kapinus, Michal (advisor)
This work is concerned by the issue of calibrating a robotic workplace, including the localization of a calibration object for the purpose of calibrating a 2D or 3D camera, a robotic arm and a scene of robotic workplace. At first, the problems related to the calibration of the aforementioned elements were studied. Further, an analysis of suitable methods for performing these calibrations was performed. The result of this work is application of ROS robotic system providing methods for three different types of calibration programs, whose functionality is experimentally verified at the end of this work.

Optical Localization System with a Pan/Tilt Camera
Senčuch, Daniel ; Musil, Petr (referee) ; Beran, Vítězslav (advisor)
The effective surveillance of large critical areas is crucial for their security and privacy. There is no publicly available and acceptable solution of automating this task. This thesis aims to create an application utilizing a combination of a pan-tilt robotic manipulator and a visible-spectrum camera. Based on the pan-tilt unit's position and camera's images, the application searches for semantically significant changes in the captured environment and marks these regions of interest.

Adaptive Planning of Industrial Robot Trajectory
Dizorzi, Matúš ; Burian, František (referee) ; Chromý, Adam (advisor)
This thesis deals with the extension of the RoScan scanning system features, making its behaviour more secure and adaptivte during scanning of the object on its whole trajectory. This work contains mathematical model of said manipulator, suggested methods to ensure proper behaviour during singularities. New features were added to the RoScan system such as control panel for manipulator control including new format of trajectory log, moving closer or further away from manipulator’s end effector and non adaptive trajectory testing for singularities. Result of this work is ready-to-use.

3D Scanning with Proximity Planar Scanner
Chromý, Adam ; Burian, František (referee) ; Žalud, Luděk (advisor)
Tato práce popisuje konstrukci skenovacího systému pro tvorbu trojrozměrných modelů. Kombinace laserového scanneru a robotického manipulátoru tvoří velice flexibilní zařízení schopné snímat jak velké, tak malé a detailní objekty. Zařízení nachází uplatnění v mnoha aplikacích, zejména v lékařství, kde přináší řadu nesporných výhod proti stávajícím systémům. Práce popisuje mechanickou konstrukci zařízení, funkční principy a jeho kalibrační proceduru. Součástí práce je i software pro vizualizaci naměřených dat a jejich zpracování do podoby modelů se stínovaným povrchem. Výsledkem práce je funkční zařízení a rozsáhlý obslužný software.
