Mobile robot control system
Řezníček, Radek ; Kříž, Vlastimil (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with differential drive wheeled mobile robot which is running under a real-time operating system. Introductory part is focused on theoretical description of robot and its original firmware. Practical part deals with creating software and implementation several methods that allow following the line by robot using reflectance sensor array. Significant part of this thesis is focused on design and implementation of communication protocol, based on IEEE 802.15.4 which provides communication between robot and PC. There is also created a PC application that allows to transmit commands to the robot and display information gained from robot.

Autonomous RC ship model
Jevická, Barbora ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This Master’s thesis deals with working on development kit, which is used for RC ship model. The basis are programmable Nucleo STM32 microcontrollers, to which other used modules are connected. The goal is to test each component and create system for navigation of the ship and wireless communication between controller and ship. GPS module and compass are used to navigate and determine the direction of the ship. Controller and ship can communicate through bidirectional wireless modules with antenna. The RC ship model can be switched between manual and autonomous modes. The main result of this thesis is autonomous movement of the ship on to a predetermined GPS coordinates and parallel communication with the user.

Wireless communication module in 868 MHz band with MESH network support
Uhlíř, Marcel ; Fedra, Zbyněk (referee) ; Povalač, Aleš (advisor)
This thesis deals with design of a wireless communication module that allows communication in the unlicensed band at the frequency of 868 MHz. The designed module can be easily implemented in various types of embedded devices using SMT technology. This communication module consists of a low-power radio frequency transmitted, balancing element, impedance matching, radio antenna and electromagnetic shielding. Communication between the embedded device and the wireless communication module is realized using the SPI interface and configurable GPIOs. Part of this work is the proposed firmware library, which operates the wireless communication module and allows communication in peer-to-peer mode and in MESH network mode. A procedure for its creation and management is created as part of the MESH network. The use of this work is directed to the field of control and sensor systems with application in automation.
