The Design of Enlargement of Sensor and Control Module of Mobile Robots Named Brontes
Husar, Jan ; Kopečný, Lukáš (referee) ; Florián, Tomáš (advisor)
This bachelor's thesis deals with the proposal of the sensory module and the control of mobile robots named Brontes enlargement. For this purpose a printed circuit board named MX05 was created, which extends its functionality via connection to the control board named LTR001.2. Construction of the board was conducted on the bases of the needs and requirements coming from robot peripherals. The proposal was created containing the control, protection and filtering features. Further, the board was realized and inhabited. Using MX05 creates a great simplification of wiring and there is implied the extension of the original features that are useful not only in robots Brontes.

Analog 0-10V to Ethernet convertor
Hlúpik, Martin ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This Master`s thesis concern with problematic of connection analog sensors with voltage output 0-10V to a ethernet communication network. Due to a quick evolution and an application ethernet nets to industry and building technologies is possible to use this solution for connection remote diagnostics and setting of existing analog sensors without bus communication interfaces on instrumentation level of field bus networks. The converter is based on Rabbit module, which can be used like webserver for setting, calibration and data recording. For purpose of wide converter use the data output will be purvey on ethernet interface by Modbus TCP and on asynchronous serial interface RS232. First part of thesis is aimed on description of existing solutions and introduction with principles of linearization and calibration of A/D converters. Description of communication standard Modbus TCP widely used in industry applications. Second part of thesis describes design a realization of project. Here is described equipment block diagram with detail description of each block and devices used. In the part of implementation is description of device firmware with program function description and control. Last part is engage with module function verification supported with plantz of measurements and tests. The thesis is ended with evaluation results, knowledge and detections found out in development of project.

GPS for Teaching HW/SW Platform
Pajgrt, Ondřej ; Bidlo, Michal (referee) ; Fučík, Otto (advisor)
The work deals with a connection between HW/SW platform FITkit and GPS device. Introduces GPS systems from theoretical and practical view desribes FITkit teaching platform and its common use and shows in detail the connection of those two systems into a cooperative unit. Work also analyses communication interfaces and protocols used for that connection. Finally it provides a description of tho whole system data flow from the very beginning in GPS unit to the final displaying on the screen and description of implementation and application usage.

Software for Communication with GPS Receiver
Vrba, Pavol ; Daněček, Vít (referee) ; Číž, Radim (advisor)
The main goal of this master’s thesis is to over study, reconsider and make a program, which will be capable to interpose information from GPS module, different markers and necessary information’s, geographic coordinates obtained from GPS will be projected in its interface and also on map. This project contains of 3 parts. The first one exactly describes GPS, its history, structure, principle, competitive types of navigations systems and also GPS’ services and technical parameters. The second part of this project describes GPS hardware, used receiver of this signal. There is also mentioned its technical parameters and communication with outside world. The third part is in scripted the software for communication with GPS receiver. We can also see the description of code, in which is mentioned communication protocol and imaging the position on the map. It was programmed in C# language on platform Microsoft Visual Studio 2008 Express Edition.

Electronically controllable frequency filters with current active elements
Suchánek, Tomáš ; Lattenberg, Ivo (referee) ; Kubánek, David (advisor)
The aim of the thesis is to study the possibilities of the electronic frequency ?lter com- posed of active elements operating in current mode. The main opportunities lie in the change control parameters, most are marginal or quality factor frequency. As the active elements are considered especially CC (Current Convejor), controllable current ampli?er DACA (Digitally Adjustable Current Ampli?er) or combination with the current tracker MO-CF (Multiple Output Current Follower). Another part will focus on the management of the above parameters using digital potentiometers and choosing the appropriate ?lter structure. The ?nal task was to digital control parameters using a PC and measuring its properties.

Application for Support of Calibration of a Piston Pipette
Vospěl, Bohumír ; Stružka, Jaroslav (referee) ; Orság, Filip (advisor)
This thesis occupies itself with the partial automation of the workflow for calibration of piston pipettes. It analyses the possibilities of the use of the current laboratory gauges, and focuses particularly on the connecting of these devices with a personal computer and their remote control. It also enables the exportation of the measured values into Microsoft Excel application and suggests a complete solution of these problems.

Measuring unit of electric power quality
Teplan, Miroslav ; Mrákava, Petr (referee) ; Mlýnek, Petr (advisor)
This thesis describes the parameters of electrical energy with a focus on low voltage characteristics and their measurement with respect to the parameters required by standards. In addition, one chapter deals with monitoring of the quality electric energy. Measurement organizations, calculation of power quality and the data collection for its calculation is referred here. For the illustration, the example of a distributed monitoring system from practice is described. The second part deals with the design and implementation of a module for measuring power quality , namely by measuring the voltage characteristics. It describes the selection of the chosen solution, hardware part and firmware for the MCU. To display the measured data, application was created by the Java programming language. The application allows the visualization of the voltage measured Low voltage grid with single phase voltage RMS value 230.
