Mobile Application for Robotic Arm Programming
Jurka, Vojtěch ; Materna, Zdeněk (referee) ; Kapinus, Michal (advisor)
This thesis describes the design and creation of a system which controls and programs a robotic arm through a mobile application. The system consists of an Android mobile application and a server. The server is implemented like a Python script to process the app communication and then send instructions to the robotic arm. This approach makes it easy to use one mobile device to control several robots independently. This solution enables the user to control and program the robotic arm in real time using intuitive control elements and to create and edit applications for the robot. All through his mobile device. The programs for the robot are created with the methods of visual programming directly in the mobile application. This way of robotic arm control contributes to the accessibility of these devices to the less professional public, which could utilize these devices.

Smart Video Doorbell Based on Raspberry Pi
Ondrejka, Adam ; Zemčík, Pavel (referee) ; Materna, Zdeněk (advisor)
This thesis is focused on the design and implementation of a smart doorbell based on Raspberry Pi. Unlike commercially available smart doorbells, the solution described in this thesis offers full functionality (motion detection, audiovisual streaming, and notifications) even without internet access. The doorbell operates fully locally and enables the user to use more doorbells at the same time. A web page and desktop app for displaying notifications was also implemented for the doorbell. After connecting to the android app Gotify, notifications can also be delivered to a device with the Android operational system.

Basic Shapes Detection in Point Clouds
Eldes, Pavol ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
This thesis deals with the topic of simple geometric shapes detection from point-clouds with a special interest in the influence of point normals on speed and quality of produced results. Its main product is an application that demonstrates detection of planes, spheres and cylinders. Detection is done using the RANSAC paradigm that is modified in this thesis to allow it to work with multiple models simultaneously. Another modification presented in this thesis focuses on enforcing stricter candidate shapes selection conditions for detection models.

Physiological Data to Analyze and Improve the User Experience
Štěpánek, Daniel ; Beran, Vítězslav (referee) ; Materna, Zdeněk (advisor)
The goal of this thesis is to obtain dataset of physiological data for user emotions in order to analyze and improve human-computer interaction. This paper proposes of the use Empatica wristband to capture physiological data and Python for data processing. After evaluation, 94 % of intact data was obtained from the expected number of samples. Based on the obtained data, it is possible to better analyze the user experience and thus improve it.

Automated Testing of User Interfaces
Meluzín, Vojtěch ; Materna, Zdeněk (referee) ; Kapinus, Michal (advisor)
The main theme of this thesis is automated testing of graphical user interfaces for the system ARTable, created using the ROS framework. My solution to this problem is an extension for a testing tool. The extension named ARTBot allows simulating user interaction. Its use can be combined with a testing tool to automate testing of garafical interface of ARTable applications. The thesis contains the design, description of the implementation and methods of testing the ARTBot.

Augmented Reality for ARTable and See-Through Glasses
Adam, Róbert ; Materna, Zdeněk (referee) ; Kapinus, Michal (advisor)
This Bachelor Thesis was created during study at the Faculty of Information Technology at Brno University of Technology. The thesis is focused on augmented reality using Game Engine Unity and ARTable system. The theoretical part contains history and augmented reality usage. Then it is defined what augmented reality is and how camera tracking works in a real world. In a practical part the thesis is focused on integration of Vuzix glasses in to Unity. The application is able to draw information about objects placed on table differently according to information obtained from ARTable. The thesis describes design and implementation details about the created application. The final part of the thesis includes test results and conclusion.

Demonstration Application for Mobile Robot
Prokopová, Dagmar ; Beran, Vítězslav (referee) ; Materna, Zdeněk (advisor)
This work deals primarily with the design and principles used for the creation of Ball Picker demonstration application for mobile robot TurtleBUT2. The robot controlled by this application is capable of picking up tennis balls spread around and placing them into the hand of a nearby person. Among others, the work describes the robot operating system the application is based on and simulator Gazebo. Also, it provides the detailed analysis of the algorithm for tennis ball detection based on the image color filtration and the usage of Hough transform as well as principles of detection with Haar feature-based cascade classifier used for human hand detection.

Robot Motion Simulator
Langer, Lukáš ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
Robot simulation is currently an essential part of robotic development and selection of the simulator plays an important role. The aim was to highlight why it is important simulation and show its advantages and disadvantages. Another objective was to map overview of current simulation tools used in robotics. The aim was to propose a number of experiments that compare the environmental Gazebo and Microsoft Robotics Developer Studio with a focus on comparing the physical properties of the simulator. Finally, it was included in the evaluation of the experiments and practical experience with the two instruments.

Smart Home: Digital Thermostatic Valve Controlled via WiFi
Bednařík, Radim ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
This bachelor thesis deals with the design and creation of a prototype smart thermostatic valve head controlled via WiFi, created by modifying a cheap digital valve head eQ-3 N. And creating a system that would support the control of these valve heads and would allow the user to enter requirements using a graphical interface. The theoretical part deals with a survey of the current market of thermostatic valve heads offered, methods of heating control using control algorithms and modules for use in modifying the valve head. The practical part describes how to modify the valve head and the implementation of the control system. Part of the work is performing several tests to verify the correct behavior of the heating control of the created thermostatic valve head.
