Enhancement of gait and control of six-legged walking robot Cerna Vdova
Krejsa, Jan ; Kopečný, Lukáš (referee) ; Kříž, Vlastimil (advisor)
This bachelor thesis deals with control, operating and remote programming of a six-legged walking robot. It is devided into six chapters. The introduction chapter is about remote programming. The second chapter describes possible walking ways of six-legged chassis. Furthermore this thesis deals with the overcoming of obstacles, thus to walking on uneven ground. The following chapter discusses the possibilities of wireless communication. The last two chapterss describes the hardware and software of the robot.

Creation of an experimental wireless sensor network
Piro, Šimon ; Šimek, Milan (referee) ; Botta, Miroslav (advisor)
In this thesis, there will be experimental wireless sensor network created. Simple mo- nitoring application will be running on this network and storing data in database. For easier maintaining of network, there will be prototype system created, which will allow remote firmware upload to network nodes. This system will use Bootloader application from Atmel company combined with Serial to Ethernet converter. This system will al- lows mass upload of firmware to nodes from any place in the world with Internet access. Information about network will be stored in database which will include table for nodes and connections where its possible to see link quality for each link in the network.

Remote maintenance of the microcontroller systems
Vágner, Martin ; Hynčica, Ondřej (referee) ; Kučera, Pavel (advisor)
This thesis deals with methods of remote maintenance of microcontroller systems based on Atmel AVR family over the Ethernet interface and TCP/IP protocols. To create communication through TCP/IP, an embedded server NE-4100T is used. At the beginning, key features of the server and methods of handling with content of a program memory are discussed. The final solution is based on the bootloader method. It includes bootloader firmware and user program for PC. The hardware part covers design of interconnection electronics, DC-DC step down converter, real time clock and printed circuit board. The remote maintenance of program memory has been sucessfully solved, but the embedded server NE-4100T produces a problem with an auhentification without a sufficient solution.

Present-day Programming Method of Microcontroller
Medla, Eduard ; Matyáš, Pavel (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to modern methods of programming microcontrollers. In this work are examined some programming languages, various programming environments and graphic editors. In every methods of programming are explained their advantages and disadvantages. Here are two examined methods of loading program to microcontroller, so called flashing. Choosed method is programming language C, which was used to programme two-state regulator with hysteresis in environment AVR Studio 6.2.

System for Programming Minerva Platform
Dohnal, Michal ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
Theoretical part of this thesis studies several concepts and interfaces being used for programming microcontrollers (MCUs) and reconfiguration of field programmable gate arrays (FPGAs) with closer look at those, which are available for MCU Kinetis K60 and FPGA Spartan-6 in circuitry given by the architecture of educational kit Minerva. This knowledge is employed in practical section which describes deployment of the supporting firmware belonging to group of firmwares so-called bootloaders. Finally the application QDevKit3 is introduced, that is based on this firmware, representing effective and fast way for easy programming of FLASH memory on Kinetis MCU using USB interface.

Secure Bootloader For Arm Microcontrollers
Prítel, Pavol
Embedded systems are single purpose devices, where software updates are often omitted or very limited in comparison with personal computer systems. Such systems are typically using microcontrollers with limited memory and computing power. Enabling software updates on an embedded system brings some security issues that need to be taken into account. As soon as there is a possibility of software update, the device is exposed to risk of malicious or not original applications being executed on the device. In this paper a reference implementation of bootloader with security features is described. As a result of using asymmetric cryptography, the memory footprint and startup time is increased significantly. The contribution of this work is in finding the right algorithm that will offer trade-off between level of security and used resources of targeted microcontroller.

The plants recognition mobile application UI Specification
Schwarzová, Kristýna ; Pavlíček, Josef (advisor) ; Kedaj, Petr (referee)
This thesis describes the design of an application for recognizing plants. The application will run on mobile platforms with Android OS. Part of the thesis is focused on creation of a database of meadow plants and creation of a paper prototype, which will verify the applicability of the designed user interface. The user takes a photo of the flower plant that he wants to recognize and the application looks up the given flower in the database. During photographing the application guides the user how to take the picture of the plant.
The first part of the thesis defines terms such as application, UI specification, Android, paper prototype and macro photography. It is focused mainly on taking photographs of plants under optimal conditions and proper camera settings. The second part includes UI specification, which consists of motivation, definition, goal definition, personification, use case, scenario, and of logical and graphical design.
