The educational model of a hand-operated balanced manipulator
Letrik, Lukáš ; Najman, Jan (referee) ; Adámek, Roman (advisor)
This bachelor’s thesis deals with a draft and an assembly of a simple uni-axial HOBM (Hand-Operated Balanced Manipulator). The research part is dedicated to the history of HOBM, basic mechanisms of mechanic HOBMs, different types of propulsion used for HOBM and their most renowned producers. The practical part of this thesis is focused on simulation, construction and programming of uni-axial HOBM for educational purposes. The thesis is concluded with an evaluation of the functionality of the constructed uniaxial HOBM and improvement proposals. Part of the thesis is also a list of used components, which were used for construction, and their datasheets with attached scripts, which comprise of a simulation and a program for operating the uni-axial HOBM. These documents are enclosed.

Extending the Laboratory Educational Kit PIC Edu Kit with a Set of Wireless Sensors
Hanuš, Tomáš ; Najman, Jan (referee) ; Sova, Václav (advisor)
This thesis describes the design and implementation of extension of laboratory training model PIC Edu Kit. It is about set of wireless sensors. These sonsors have to measure temperature and deformation. Mesure of temperature was realized by temperature resistive sensor Pt100 and deformation by resistive tenzometr. These wireless moduls comunication on protocol Wi-Fi. In this work is introduced propose of measuring dictucts for measure of temperautre and deformation. There is evidenced their realization, showed software for receiving dates on PC and programme for the microcontroler.

Measuring station with data transmission via 4G network
Pernica, Michal ; Bastl, Michal (referee) ; Najman, Jan (advisor)
The bachelor thesis is concerned with data transfer via 4G network from a measuring station to a web server. The first part presents the possibilities of transmission via 4G network using the SIMCom 7600E-H module. The ways how to assemble the measuring station or how to make a web server for saving and displaying the measured data are introduced. In the second part, the individual types of transmission are tested and live data transmission and interval data transmission is also implemented based on the results from the first part. The thesis also notes the procedure for setting up a server and a web application for displaying data or assembling and programming a measuring station.

Visual servoing for humanoid robot
Nedvědický, Pavel ; Bastl, Michal (referee) ; Najman, Jan (advisor)
This thesis deals with construction of a cheap robotic manipulator, which should be used for exhibitions and educational purposes. This project is a teamwork of two students. A robotic arm with four degrees of freedom was developed. Control and power electronics were installed for whole robot. The software’s aim is to develop a software that can control the robot by visual feedback, obtained from image processing of an image from 3D camera. Lastly, a graphic user interface for robot movement control is presented.

Autonomous assembly using the UR5e robotic arm
Cesnek, Martin ; Formánek, Martin (referee) ; Najman, Jan (advisor)
This bachelor thesis deals with the demonstration of the abilities of collaborative robots in practical use. These abilities are demonstrated in a task where the robot autonomously composes a predefined shape from LEGO cubes. The UR5e robot from universal Robots was used together with the OnRobot RG2 gripper to carry out this work. Communication with the robot is ensured by the Maltab environment with the use of the library created at ÚMTMB from BUT FME. The first part of the work is devoted to getting acquainted with the used hardware and introducing the functions of the library together with setting up the communication between the robot and PC. There is also paid attention to the analysis of possible solutions to the problem of stacking LEGO cubes. The second part presents the methodology and elaboration of structural elements together with control software for robot motion control and data processing from sensors. The result is a demonstration in which the user enters the input parameters of a rectangular 3D shape according to which the robot autonomously composes the given shape.

Design and testing of the system for localizing a sound source
Havelka, Martin ; Vechetová, Jana (referee) ; Najman, Jan (advisor)
This bachelor’s thesis deals with possibilities of sound source localization. There are generally mentioned possible hardware and software solutions at the beginning, from which two applicable methods and suitable components of test device are selected. Further there is a practical part of this work, where programmed algorithms are described. An essential part is testing. Accuracy is tested for the selected microphone array, depending on the change in the number and position of the sensors, the effect of ambient noise, and the location of the obstacle in the area. The output of the tests is the evaluation of functionality and accuracy for both methods used.
