Gate Unlocking by Voice
Bauer, Jan ; Pešán, Jan (referee) ; Schwarz, Petr (advisor)
The aim of this BSc. thesis is to create a device for authentication based on human voice. The solution is based on the BSAPI speech processing library developed by Phonexia. The library written in C++ was ported to the Raspberry Pi B+ device. The core functionality of the application was implemented in a Python script. The resulting solution is certainly interesting and may become a reliable security system in near future.

Control and Position Stabilization of a Small Flying Drone
Martinec, Adrián ; Zamba, Martin (referee) ; Strnadel, Josef (advisor)
The goal of this thesis is to create a drone in a form of a plane, driven by autopilot. I have solved the selected issues using a theory of flight and regulators from an automatization area. The text describes a functional solution. Unfortunately because of an accident, no final tests were performed. A contribution of this work is in exploring a functionality of various parts that are used with a drone building process. That includes a use of regulators and creation of libraries driving those parts.

Recognition of Home Appliances Based on Their Power Consumption Characteristics
Vaňková, Klára ; Černocký, Jan (referee) ; Schwarz, Petr (advisor)
The goal of this master's thesis is to design and implement a system for recognition of home appliances based on their power consumption characteristics. This system should identify the individual home appliances from measurements of the total household consumption. The acquired data could be used for statistics of usage of a particular appliance and subsequent detection of errors or non-standard behavior of the measured device. An important part of my work is a design and hardware implementation of a unit for measuring and a system for processing the measured signal. The first version of my project uses pulse output of an electrometer to measure the energy. This method does not provide a sufficient sample rate but it's a quick way to obtain data for processing and analysis. The second version monitors the power consumption with a multi-purpose AC converter which measures active and reactive power with the desired sample rate. The data is then processed and recognized by two classifiers - HMM and KNN.

Configurable Embedded Photo/Video Trap with Storing Data and Self Adaptation to Surroundings
Výborný, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This diploma thesis deals with a design and construction of an embeded camera trap with a video recording and night vision support, which is able to self adapt to surroundings. The device is based on the Raspberry Pi platform and configurable by touch screen control with a user-friendly graphical interface. Also the web-application for easy remote administration was developed in Ruby On Rails framework. The camera trap was built and successfully tested under the real conditions. There are also typical application cases and requirements for camera trap construction described in this thesis.

Motion Controlling of a Robotic Car by RaspberryPi and Camera
Brhel, Miroslav ; Samek, Jan (referee) ; Rozman, Jaroslav (advisor)
This Master's Thesis deals with the controlling of robotic car by Raspberry Pi and the ca- mera. Theoretical part describes individual steps of image processing and probabilistic plan- ning for searching path in the work space. In particular, algorithm RRT (Rapidly-exploring Random Tree) is discussed and the balanced bidirectional RRT is further introduced and used for nonholonomic planning in configuration space. Next chapter speaks about propo- sed solution and there is the accurate description of connection Raspberry Pi to the robotic car. Rest of the work provides look at implemetation details and evaluation. In the end, conclusion was given and some improvements were suggested.

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.

Sensors and motor control of mobile robot
Zatloukal, Jiří ; Věchet, Stanislav (referee) ; Marada, Tomáš (advisor)
The diploma thesis is dealing with the proposal and realization of the sensor and drive system of the four wheel mobile robot. The control unit is a miniature computer Raspberry Pi. The robot will be employed in the future for the environment mapping and location. For this purpose robot exploits the different types of sensors. The information of these sensors is being processed by the Xmega microcontroller. Another microcontroller together with H-bridge DRV-8432 is used to control the direct current drives.

Realization of fingerprint scanner
Kovář, Martin ; Sekora, Jiří (referee) ; Mézl, Martin (advisor)
This master’s thesis deals with the issue of scanning human fingerprints, which is currently very topical and represents the most widespread biometric technology. The theoretical part of the work acquaints the reader with basics of dactyloscopy and biometrics and concerns technologies used for fingerprinting, image preprocessing methods and commercially available contactless optical scanners. The practical part is a realisation of a contactless optical scanner based on a Raspberry Pi minicomputer, implementation of preprocessing algorithms in Python and testing of the device from the perspective of image quality.
