Remote control of Solar inverter
Pohorský, Ondřej ; Kopečný, Lukáš (referee) ; Burian, František (advisor)
This thesis deals with the design and implementation of a remote monitoring device for the solar inverter SOFAR HYD-10-KTL-3PH. The assignment of this thesis was based on the knowledge and requirements of the author. The aim of this thesis is to create a device communicating with the inverter. The device will display the essential parameters on the website. From the website it should also be possible to control the outputs of the device, which can be used to switch appliances.
Concept design of a multi-environment mobile robot
Zezula, Benjamin ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
This thesis presents the design of a multi-enviroment mobile robot that combines the simple principle of movement both in water and on land. In particular, the design of a~four-wheeled vehicle is presented, whose innovation lies in the use of blades on the rear wheels. A suitable type of propulsion system is chosen based on a~study of~different types of~robots. During the research of already functional solutions, great emphasis is put on the advantages and disadvantages of~the different actuators as well as their mathematical and physical analysis. The proposed solution includes the proven design of four differentially controlled wheels for movement on land and the use of~blades on the rear wheels for movement in water. This concept is described in detail using a~mathematical-physical model, on the basis of~which a~working prototype has been developed. The thesis concludes with an experimental verification of~the agreement between the mathematical model and the real prototype. This verification focuses on the motion dynamics and the behaviour of the robot in different environments. The differences observed are attributed to external influences such as the resistance of the gears or the manufacturing tolerances of the individual components.
Li-ion Batery Management System
Kratochvíla, Lukáš ; Macho, Tomáš (referee) ; Kopečný, Lukáš (advisor)
This thesis is about systems for Li-ion batteries. The system consists of measuring and charging. The main part of system is 3 to 5-Series Cell Li-Ion and Li-Phosphate Battery Monitor chip BQ76920. The result of this thesis is printed circuit board (PCB) with BQ76920 and a box contain PCB and battery pack. Box is designed for robot KAMBOT. The system has been tested and measured and evaluated in this thesis.
Localization of RF transmiter
Mikuláštík, Jiří ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
The thesis deal with possibility of localization of avalanche victims. Main focus is for RF avalanche beacons. The major objects of this thesis are design and construction of this device. A large part of thesis describes design of avalanche beacon and particular steps of realization. The design take into account the compatibility with commercial beacons. The paramters of designed device are verified by testing and measurement.
Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.
Process control of a distillery
Sejkora, Martin ; Kopečný, Lukáš (referee) ; Veselý, Libor (advisor)
This master‘s thesis deals with the design of a control system for a distillation column. It deals with the issue of distillate production and acquaints the reader with the necessary knowledge that is necessary to understand the purpose of the work. The practical part of the work presents a specific distillation column, the means for its control and the method of implementation of the control system, then the visualization of the control system and the method of control. Part of the work is the evaluation of the results and benefits of the work.
Battery charger
Paták, Michal ; Kopečný, Lukáš (referee) ; Burian, František (advisor)
This diploma thesis deals with battery charging. The thesis describes qualities and possi-bilities of lithium battery charging. The charger is independent on the input voltage and recharges batteries carefully. Due to a careful recharging process it is needed to measure the voltage at various cells of the battery and then balance this voltage. Since the charger is to be implemented in a robot, it is needed to switch the operation from an external source and the battery. The first part of the project deals with qualities of batteries and the way of their recharging. In the second part I design an individual blocks charger. In the third part I deal with a communication with a computer charger and data visualization. And in the last part I designed a program for the charger.
APU unit for KAMbot robot
Duz, Aleksei ; Kopečný, Lukáš (referee) ; Burian, František (advisor)
This thesis deals with design and creation PCB unit, which will provide protection Li-Ion battery for KAMbot robot. The aim of this work is to design, revive and programm PCB board, whitch will be connected to 4-cells Li-Ion battery and will protect it. The work is divided into 4 parts. The first one deals to parse different ways to protect the battery. The second part occupy design and creation PCB board for protection of aLi-Ion battery. The third section deals to programm microcontroller, communicate with chip that it protects battery and control the protection unit. The fourth part presents results of efficiency tests for protection Li-Ion battery unit.
3D Printer Control System
Vítek, Radim ; Kopečný, Lukáš (referee) ; Arm, Jakub (advisor)
This thesis describes ways to controll 3D printers. Especially controlling stepper motors with their motion profiles. Furthermore discusses about interpolation algorithms. Attention is also paid to the design of the control board for the 3D printer built on kit Nucleo F411. The last part describes implementation of controll firmware.
Robot for disabled drivers
Amler, Ivo ; Kopečný, Lukáš (referee) ; Šolc, František (advisor)
Project deals with design of a control system for control of electric vehicle for disabled persons. The project represents a feasibility study that will be used for construction of a real system. For gaining information about position of the vehicle, it was managed to create only incremental sensor for calculation these position.
