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.

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.

Sensors and motion control for humanoid robot
Chlaň, Jakub ; Křivánek, Václav (referee) ; Najman, Jan (advisor)
The presented diploma thesis deals with the design and construction of a simple humanoid robot with two arms attached to a torso. The work was solved as a team project of two authors. Therefore, only the construction of the arm, which is inspired by the kinematics of the human arm is described in more detail. Its construction was the task of the author. An important part of the work is the selection of drives and sensors for the operation of the mechanism. Furthermore, the work presents the procedure of creating a kinematic model of the arms to solve the forward and inverse kinematics problem. For the possibility of motion control, the control of the control unit in Simulink was designed and the drive control was created.

Design of communication interface in WBAN systems
Kandera, Tomáš ; Najman, Jan (referee) ; Krejsa, Jiří (advisor)
Táto diplomová práca sa zaoberá technickou realizáciou WBAN zariadenia, ktoré je schopné súbežne komunikovať prostredníctvom dvoch bezdrôtových komunikačných protokolov. Rešerš dostupných riešení je dostupná s hodnotením jednotlivých produktov podľa vopred stanovených kritérií. Návrh z hľadiska software obsahuje tvorbu vlastného BLE servisu, konfiguráciu Timeslot API a periférií často využívaných vo WBAN zariadeniach. Výroba dosiek plošných spojov pre zariadenie a dedikovaný ovládač zahŕňa vlastnú anténu, nabíjací obvod batérie a nRF52810 čip. Testovanie prototypov je zhrnuté v poslednej kapitole spoločne s experimentálnym meraním útlmu živočíšneho tkaniva.

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 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.
