Sign language detection methods - review
Petr, Luboš ; Venglář, Vojtěch (referee) ; Krejsa, Jiří (advisor)
The Aim of this work is to describe various methods of sign language detection. The output of individual methods is a functional translation of sign language into text in real time. In addition to glove and kinect detection, this work deals with the possibilities of sign language detection from image recording, which is the most prospective method of detection in the future. The thesis is also focused on sign classification using neural networks.

Design and implementation of the sensor network technological sample for diagnostic purposes
Venglář, Vojtěch ; Krejsa, Jiří (referee) ; Věchet, Stanislav (advisor)
The purpose of this thesis was to design and implement a prototype of binary topology sensor network (as proposed in patent CZ 306855 B6). Important part was evaluation of this type of network. A survey of commonly used sensors and technologies used in intelligent buildings and sensor networks was created. The gathered information was used for the evaluation. A network for analog signal transmission was designed and implemented (including all the elements) based on the patent proposal. A number of configurations was proposed to test the network features. Measurements were performed using all the proposed configurations. Two devices were used for the measurement: STM32 Nucleo F303K8, MyRIO (by National Instruments). Looking at the measured data, we can tell that the consistency is good enough to declare this network functional as a concept. However, we cannot recommend this type of network for high precision applications at the time, due to some accuracy and consistency issues. We have also detected relatively significant noise in the data. That could be caused by many external influences, partly by faulty design of the components.

Design of mobile robot cover
Bláha, Pavel ; Venglář, Vojtěch (referee) ; Krejsa, Jiří (advisor)
This bachelor thesis deals with the design and construction of a mobile robot external casing. A robot could be used for transporting cargo. At the beginning of this thesis, there are briefly described technologies, which can be used to produce a robot casing. Part of this thesis is the variant design study, showing few possible rough plans of robot casing shapes. The thesis also includes a calculation dealing with the problem of robot cooling. Result of this thesis is a constructional solution related to suitably chosen production technology. The constructional solution has to comply with predefined requirements.

Design of mechanical subsystem of tester for touch screen devices
Kopčil, Tomáš ; Venglář, Vojtěch (referee) ; Krejsa, Jiří (advisor)
Cílem této práce je navrhnout a sestavit systém pro automatizované nepřetržité testování dotykových displejů. Práce je zaměřena na mechanickou část, koncový efektor a motorizaci. Navržený koncový efektor je funkční na kapacitních dotykových displejích, přičemž snímá přítlačnou sílu působící na displej. Pohyb zařízení je zajištěn lineárními pohony s ozubeným řemenem, které jsou polohovány krokovými motory. Pro komunikaci s budiči motorů přes SPI protokol a pro samotné řízení motorů byla vytvořena knihovna zajišťující jejich lichoběžníkový rychlostní profil při pohybu. Sestavený testovací systém byl podroben 24 hodinovému spolehlivostnímu testu, během kterého byla ověřena jeho funkčnost, přesnost a opakovatelnost. Bylo také potvrzeno, že splňuje veškeré požadavky.
