Design and implementation of a control unit for the aquarium environment
Petrák, Lukáš ; Formánek, Martin (referee) ; Krejčí, Petr (advisor)
This bachelor thesis deals with the design and implementation of a prototype control unit for controlling the internal environment of an aquarium. The aim of this work is to create a device that will control the aquarium lighting using available LED strips of different colors, as well as maintain the aquarium water temperature within the range set by the user. It will then record on an SD card the progress of the lighting, the water temperature from the three sensors and the time when these values were obtained. These measurements can be retrieved and the device can be controlled via a web interface from a standard browser. The device should realizable from commonly available modules and components and its parameters should satisfy both the beginner and the advanced aquarist who, from the analysis of the measured values of the aquarium's internal environment, will adjust the control unit according to his needs.

Construction of educational model "Ball on Stick"
Coufal, Ondřej ; Formánek, Martin (referee) ; Dobossy, Barnabás (advisor)
The goal of this thesis was to create an educational model, which could be used as a demonstration of dynamic model and its regulation for future students of mechatronics. The construction was inspired by a similar construction but with much smaller dimensions where most of components were printed by a 3D printer. Afterwards there was created an electrical scheme and implemented on a printed circuit board. For the whole system was designed a caskade regulation, that makes sure the ball will reach the desired position, which is adjustable.

Prestressed bridge No. 209 over the expressway R2 in Slovakia
Mareček, Tomáš ; Formánek, Ing Martin (referee) ; Koláček, Jan (advisor)
This thesis deals with a design of the bridge for second class highway S7,5 through speedway R2 in Slovakia. From the three proposed versions the version with unicameral structure was chosen for further detailed analysis. The longitudinal direction of the structure is designed as continuous three fields. The lenght of the spans is 23,1 + 33,0 + 23,1 m. Detailed design of the selected version of the structure of prestressed concrete bridge is processed according to limiting conditions, including consideration of the impact of the progressive construction of the bridge. It is elaborated a detailed structural analysis including drawings and visualization.

Possibilities of controlling the output characteristics of the peristaltic pump
Odehnal, Martin ; Formánek, Martin (referee) ; Jagoš, Jiří (advisor)
This bachelor's thesis deals with the possibilities of controlling the output characteristics of a peristaltic pump. First, the peristaltic pumps themselves, their design and principles of operation are analyzed. Furthermore, their applications and a description of their use in biomedical applications are described. The main part of this review describes the output characteristics of a peristaltic pump with a follow-up chapter devoted to the possibilities of their control. Here, the options are divided according to their nature into three groups: software, hardware and their combinations. The possibility of variable speed control during the cycle belongs to the category of software control and its implementation is performed in the practical part of this work. This option was chosen due to its universal use, both in the elimination and modulation of pulsation. As part of the work, different schemes were designed that allow variable control of the rotor speed of the stepper motor during one revolution in four modes according to the choice of speed profile.

Design of highway bridge
Luberová, Lucie ; Formánek, Ing Martin (referee) ; Zich, Miloš (advisor)
The subject of this bachelo r’s thesis is the design a new supporting bridge construction in Prešovský kraj, district Levoča the territory of Slovak Republic. This object is located on the highway D 26,5/120, at kilometer 13,499 795 and communication of third class – 131-00 bridges. The objective is the design of a perpendicular four-span construction, which is proposed in three variants. The first variant is a chamber girder with inclined walls from post-tensioned concrete height 2,480 m. The second variant is composed of two beamed cross-section and the third variant is composed of one beamed cross-section. For detailed assessment the first variant was chosen with a length of bridging of 166,000 m. The calculation of load effects is done by software Scia Engineer and compared with a manual calculation according to current standards. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

Assembling and creating tasks for an interactive robotic head
Szabó, Michal ; Formánek, Martin (referee) ; Bastl, Michal (advisor)
This bachelor’s thesis deals with the creation of the model of an interactive robotic head. The work itself is divided into two parts, theoretical and practical. The theoretical part is devoted to an overview of the types of robotic heads, a brief description of the available tools for recognizing objects in the image and tools for recognizing spoken speech in real time. The practical part is focused on the tools used in programming of this model, the electronics used and the resulting model of the robotic head. Finally, there are described programmed functions enabling various ways of the interaction with humans. The work includes function scripts programmed in Python.

Development of a SW for automatic processing of photographs from measurements using an erosion bridge
Dobrovolný, Lukáš ; Formánek, Martin (referee) ; Adámek, Roman (advisor)
This bachelor thesis deals with development of software for automatic processing of photographs from erosion bridge measurements. The software is developed in cooperation with the Faculty of Civil Engineering of Brno University of Technology. The aim of the thesis is to develop a program for automatic evaluation of measurements that are recorded by means of photographs and make the processing simple for user. Standard image processing methods are used for automatic evaluation. The software also includes a graphical interface in which the user has an overview of the processing and its results. The output of the measurements is a soil profile curve, which is then saved in format suitable for further use. The software also allows the comparison of two such curves and determines the difference in area between them. Furthermore, a method is designed to determine the actual dimensions of the output curve, its accuracy is then compared with an existing method.
