Kratochvíl, Jaromír ; Mašek, Petr (referee) ; Růžička, Michal (advisor)
This thesis deals with designing 3D scan method for visualization of laser beam. The first part deals with the division of 3D scanners and explains how they work. The second part compares various image processing tools and selects the most suitable for this work. The third part proposes a solution that explains the individual methods that were used or considered for this work. The fourth part deals with the solution, explaining how the methods has been created. The next part deals with practical experiments where proposed solutions are applied to different objects in different positions. The last part is the conclusion summarizing the results of this work.
Battery management systems for mobile robotics
Brabenec, Petr ; Mašek, Petr (referee) ; Hrbáček, Jan (advisor)
The goal of this bachelor’s thesis is research study of systems mainly used for monitoring, charging and balancing of battery packs – Battery Management Systems (BMS). These systems are necessary for reliable service of vehicles with electric drive and battery power. Study is aimed mainly on BMS used with LiFePO4 cells.
RFID based attedance system design
Krejzek, Jakub ; Mašek, Petr (referee) ; Věchet, Stanislav (advisor)
This thesis describes the design of applications for attendance system. The first part describes today's modern applications and basic information about RFID technology. The second part deals with the design, of SQL database applications and own attendance system application. The last part describes the instructions and suggestions for possible improvements and expansion, which is described in the conclusion.
Interactive web applications for support of teaching signal processing
Mašek, Petr ; Rajmic, Pavel (referee) ; Záviška, Pavel (advisor)
The bachelor thesis deals with the topic of processing one-dimensional signals. Five interactive web applications have been created in JavaScript to support teaching. These are applets that relate to the following topics: rational number resampling of the discrete signal, mean and root mean square signal values, discrete linear and circular convolution in 1D, and discrete cross correlation. The thesis introduces each topic by a theoretical foreword, followed by description of implementation and user interface of the created applications and further there is a commentary on the development and testing of applets.
Desing of method for position detection of autonomous convoy vehicles
Krysl, Jakub ; Mašek, Petr (referee) ; Věchet, Stanislav (advisor)
This thesis deals with autonomous convoy vehicles control methods. A real 1:10 scale model was choosen as a control and testing platform. As the main computaion unit serves the BeagleBoard xM which runs the used detection method.
Sensor system design for mobile robot based on ROS framework
Tomáš, Petr ; Mašek, Petr (referee) ; Věchet, Stanislav (advisor)
The essence of this master thesis is design and implementation of sensor system based on robotic framework which is called ROS (Robot Operating System). The main task is to perform detailed analysis and test of capabilities of the framework with final implementation on specific robot application (sensor system) with following evaluation of applicability of the system in mobile robotics. As parallel aim is to create detailed general and practical guide for beginners with ROS which they are also beginners in Linux based operating systems.
3D scanning method of environment via Kinect sensor
Kumpán, Pavel ; Mašek, Petr (referee) ; Růžička, Michal (advisor)
This bachelor thesis deals with the use of Microsoft Kinect sensor to create a three-dimensional model of the environment. The thesis describes a method for scanning the environment and its implementation for common CPUs and GPUs. The outcome of this work is an application that allows scanning the environment and creating a model in the form of a point cloud or a polygon mesh.
Design and implementation of UAV SW architecture
Kuchař, Vojtěch ; Mašek, Petr (referee) ; Krejsa, Jiří (advisor)
This thesis describes design and implementation of SW architecture for autopilot of unmanned aircraft including flight data logging, integration of automatically generated code from Matlab Simulink and communication with ground station.
Implementation of the LoRaWAN Communication Technology Using the Network Simulator 3
Mašek, Petr ; Pospíšil, Jan (referee) ; Mašek, Pavel (advisor)
The diploma thesis focuses on the description of LPWAN (Low Power Wide Area Network) technologies for use in IoT (Internet of Things) communication scenarios. The theoretical part compares communication technologies operating in the license-exempt frequency band, i.e. Sigfox and LoRaWAN (Long Range Wide Area Network). Furthermore, technologies using the licensed frequency spectrum are discussed, specifically, attention is focused on NB-IoT (Narrow Band IoT). Emphasis is placed on LoRaWAN technology and the properties of the unlicensed frequency band below the 1 GHz, which is utilized by this technology. The practical part of the thesis consists of the evaluation of simulation scenarios using an integrated module in the simulation environment NS-3 (Network Simulator 3). Attention is focused mainly on the analysis of data transmission success using selected communication parameters of LoRaWAN technology. The obtained simulation outputs with a focus on mMTC (massive Machine-Type Communication) communication scenarios confirm the relationship between the number of end devices and gateways, communication distance and transmission reliability, or the limit value for the duty cycle.
Design of control board for autonomous mobile robot.
Mašek, Petr ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
This bachelor's thesis deals with design and realization of the control board, that enables the control of an autonomous mobile robot. Simultaneously it deals with possible control alternatives of the similar robots concerning the construction. The outcome of this thesis is the control board, that communicates with the computer via the Bluetooth technology. The position of the robot is controlled via two differential drives and few infrared sensors are used to collision avoidance. The board is composed of standard parts available.
