Embedded System for Water Consumption Registration
Hajdík, Tomáš ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
The bachelor thesis deals with the issue of the status of wireless water meters.The goal is to design and implement a function prototype of the embedded system based on ESP8266 Wi-Fi module that is capable of registring the amount of water, consumed by individual users, via the wireless meter readout. Users can be identified by a contactless RFID card. Embedded system ensures its availability and makes data available to the administrator via Wi-Fi network. The administrator interacts with the system by using a mobile phone and an application running on the ESP8266. The work includes hardware design and software implementation using C++ programming language. The result is a functional prototype of the system that brings new possibilities in the sphere of wireless meter readers because it does not require unaffordable and highly specialized appliances for recording consumption, is accessible from the mobile phone and thus extends the market to ordinary consumers as well.

Measuring of Electricity Consumption Utilizing Current Transformer and Arduino Platform
Pokorný, Rostislav ; Pokorný, Jiří (referee) ; Štůsek, Martin (advisor)
The aim of this bachelor thesis is implementation of non-invasive platform for measuring the consumption and production of electrical power. Developed device enables visualization of measured data on display. Electric current is measured by non-invasive current sensor equipped with split core made of ferrite. Measured data are processed on single board microcomputer called Arduino. The device enables wireless communication with a server platform that allows visualization of measured data in a simple graphical user interface based on the ThingSpeak platform. Created device can measure consumption or production of electrical power on appliance with maximum current up to 30 A without need of any changes in electric circuit.

Solar pool heater
Jablončík, Lukáš ; Chladil, Ladislav (referee) ; Šteffan, Pavel (advisor)
The master´s thesis deals with the design of the solar heating regulator of the swimming pool. The basis was to study the available solutions for the solar pool controllers, to define the requirements, to design the concept and the block diagram of the own thermostat. The thesis also provides a description of several for the Internet of Things. The most suitable is used to control the thermostat. The resulting thermostat regulates two power outputs for filtration and the pump, it can be set using the keyboard and graphic display. At the end of the work is practically verified functionality on the model and on the real pool with solar heating.

Six-legged Walking Robot
Kotrík, Lukáš ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
This thesis focuses on design and construction of a walking six-legged robot. It consists of several parts which are exploring the process of design and construction of this robot. The thesis begins with the explanation of problematics of walking robots and then moves on to description of designing the robot. Further, the skeleton of robot is designed and the torque in each leg joint for every hypothetical servomotor is calculated. In next part, suitable servomotor is picked according to specific criteria and after that, the main board for robot and program microcontroller are created on same board with programme which we also created. In addition, an application named ConnectMe was created for wireless communication with robot. In the end, the entire construction process of robot is clarified.
