Measuring station with data transmission via LoRa network
Nguyen, David ; Formánek, Martin (referee) ; Najman, Jan (advisor)
This thesis deals with the data transmission from the measuring station via LoRa network. The goal is to research possible solutions of data transmission using a LoRa technology and to select suitable hardware for creating a measuring station. Subsequently, setting up radio module with sensors and developing web application that will collect, store and present the data from the measuring station. This thesis includes tests of power consumption, range and transmission reliability of the end node.

Test stand for DC motor control units
Procházka, Jan ; Adámek, Roman (referee) ; Najman, Jan (advisor)
Main focus of this bachelor thesis is construction of testing stand for master-slave driver units with possibility of using more slave units at the same time. Theoretical part is about DC engines and sensors. Practical part is about testing components, construction of mechanisms, which are mented to test different variants of controlling DC engines. For every mechanism is created program in SIMULINK. With thesis is included list of used components, script with subsystem for each mechanism and file with wire description and basic troubleshoot.

Collaborative robot with adaptive grippers
Vondráček, Jakub ; Appel, Martin (referee) ; Najman, Jan (advisor)
This bachelor thesis deals with collaborative robots and adaptive grippers with a focus on practical testing of the UR5 robot from Universal robots with adaptive grippers Onrobot RG2 and Robotiq 3F, which are available in the mechatronic laboratory of the Faculty of Mechanical Engineering of Brno University of Technology. In the first part of the work, a search is performed, which presents the basic issues of collaborative robots, adaptive grippers, force sensing, as well as the possibility of software simulation aimed at testing the available collaborative robot. The second part of the work presents the methodology and development of practical work with the robot, which is focused on testing all the basic functions of the robot on simple tasks. The last section of the thesis shows a simulation of a more complex robot task from engineering practice using selected software.

Visual odometry for robotic vehicle Car4
Szente, Michal ; Krejsa, Jiří (referee) ; Najman, Jan (advisor)
This thesis deals with algorithms of visual odometry and its application on the experimental vehicle Car4. The first part contains different researches in this area on which the solution process is based. Next chapters introduce theoretical design and ideas of monocular and stereo visual odometry algorithms. The third part deals with the implementation in the software MATLAB with the use of Image processing toolbox. After tests done and based on real data, the chosen algorithm is applied to the vehicle Car4 used in practical conditions of interior and exterior. The last part summarizes the results of the work and address the problems which are asociated with the application of visual obmetry algorithms.

Barcode scanner connected to a server database
Hrůzek, Jan ; Bastl, Michal (referee) ; Najman, Jan (advisor)
This thesis deals with barcode scanning on Raspberry Pi and subsequent work with server database system. There is a detailed analysis of principles of working of scanners and database systems and their selection for the purpose of this thesis. The settings and behavior under different conditions of the chosen scanner are analyzed and proper settings for different situations is suggested. Python is used as a programming tool, and a simple application for scanning and working with the database with a simple graphical interface, which was created as part of the work, is described along.

Design of construction and control algorithm for unstable robot with spherical base
Špila, Filip ; Najman, Jan (referee) ; Spáčil, Tomáš (advisor)
This bachelor's thesis deals with the complete design, manufacture, and control of an unstable robot, balancing on a spherical base, also known as ballbot. The complete design of the construction, motor unit selection, design, implementation testing of an intelligent control algorithm to keep the robot in a meta-stable equilibrium is assumed. Multiple tools such as Matlab/Simulink are used for this approach. It also includes the final implementation of the code in the PIC microcontroller. The project has an interdisciplinary character and is meant to be done as teamwork whereby each team member has a strictly defined role.

Development of database of mechatronic models in Simscape
Al-Dailami, Zaid Abdulqudos Abbas ; Najman, Jan (referee) ; Bastl, Michal (advisor)
Tato práce se zabývá především vývojem databáze modelů mechatronik v nástroji Simscape. Je rozdělena do tří hlavních částí a to následně: První část popisuje nástroj Simscape a jeho možnosti . Práce poskytuje návrh, jak nastroj použít při vývoji modelů a jak se liší od jiných způsobů modelování. Druhá část obsahuje některé mechatronické modely založené na Simscape. Některé z modelů jsou také vytvořené pomocí standardního modelování Simulinku, a ty lze porovnat s dříve uvedenými modely. Třetí část je zaměřena na jeden z dříve navržených modelů se stejnosměrným motorem. Tento model se používá k vyhodnocení, odhadu a optimalizaci skutečných parametrů stejnosměrného motoru, obsahuje také popis, jak vygenerovat c kód z modelů Simscape, abychom jej použili v HIL.
