Indoor localization based on UWB technology
Bauer, Jan Jiří ; Vyroubal, Petr (referee) ; Čech, Ondřej (advisor)
This bachelor thesis is exploring ways to localize an object in space, primarily using UWB technology. Diverse ways to determine distance (TWR, RSSI, TDoA), location in space (triangulation, multilateration, particle filter), and filters (LSM, Kalmann filter) are explained. Using development board ESP-32 UWP Pro localization system is realized, using TWR and particle filter. This system was calibrated and tested in a real environment.

Multipurpose IoT unit for wireless current measurement in HV networks.
Haluška, Daniel ; Kuchař, Karel (referee) ; Rusz, Martin (advisor)
The aim of this thesis is to design and implement a system consisting of a local unit and sensors that enable wireless current measurement in power lines. The introduction focuses on the exploration and detailed analysis of wireless technologies, their properties, parameters, and application possibilities for the proposed system. Furthermore, the thesis examines time synchronization methods to achieve coordinated current measurement across different phases of the power lines. The result of the thesis is a developed device model, its circuit design, software solution, and mechanical construction. A significant part of the work is dedicated to the implementation of the system's software solution and communication based on the ESP-NOW protocol.

Automation of RC Models Control
Vávra, Jan ; Musil, Petr (referee) ; Zemčík, Pavel (advisor)
This thesis is about controlling RC model with microcontroller ESP-32 through WiFi enabled mobile device with OS Android. Goal of this thesis is to make controlling RC model easier and more fun. Parts of this thesis are dealing with using pulse width modulation to control servos, creating a user interface and making a protocol for comunication between RC model and mobile device. Result of this work is application on OS Android, which sends instructions on microcomputer, that controls steering servo and elecromotor. System has predefined stunts on microcomputer and operator has a choice of defining custom stunt in application, which is send to microcomputer in series of individual instructions.

Ambient driven LED stripe driver
Krivý, Ladislav ; Kledrowetz, Vilém (referee) ; Pavlík, Michal (advisor)
For rooms with more complex LED lighting installations, there is often a problem of control granularity. Fine granularity often requires cluttered installation with multiple dimmers while a simple switch provides far too little granularity. This thesis describes a prototype design of a multi-channel LED PWM driver controlled by a smartphone, with an option for user automation based on ambient conditions. An LED driver with a simple web interface with the ability of automation solves both the problem with granularity of controls as well as fills the need for separate ambient-driven light installations.

Peristaltic Pump Controll Unit
Charvát, Jakub ; Kopečný, Lukáš (referee) ; Ligocki, Adam (advisor)
The work deals with the problematic of peristaltic pumps and it collects theoretical background information of this topic. The primary goal of the work is the implementation of peristaltic pump and the implementation of protection against equipment damage by overpressure. The overpressure evaluation system in this thesiss on the principle of current measurement of the motor pump. In this work, this premise is successfully tested and applied to the device. Another goal of this work is to create a desktop application that will monitor and control the pump. he data between the application and the device were successfully transfered by the MQTT communication protocol. The communication between the computer and the pump has been tested successfully.

Autonomous Model-Car Driving
Stojan, Radomír ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
This thesis focuses on the topic of creating autonomous parking systems . Based on the analysis of existing studies , a parking algorithm is presented for a vehicle model NXP Cup Alamak . This model was retrofitted with sensors in order to accurately measure vehicle speed and distance to surrounding obstacles . The proposed algorithm allows the vehicle model to autonomously detect and analyse available parking spaces , determine how to park in these parking spaces and to perform the parking maneuver if the dimensions of the parking space allow it .
