Control of sliding window in passenger car
Keprt, Jaroslav ; Vejlupek, Josef (referee) ; Lamberský, Vojtěch (advisor)
This bachelor thesis deals with the installation of power electronics on the PCBdesign and control algorithm for the DC-motor function, which is part of the window motion control system for a passenger car. The paper describes the principles of function state machines that are easily programmed using Stateflow and implementation of control algorithm in the PIC microcontroller. The control program is designed in Simulink and Stateflow its superstructure using Kerhuel Toolbox.

Photopolymer length variation measurement
Novotný, Jan ; Vejlupek, Josef (referee) ; Matějásko, Michal (advisor)
This thesis deals with development of a special measuring device designed to measure changes in lenght of a photoactuation polymer. The length of a sample of the polymer shortens by tenths of a milimetre by being lit by intensive light. The sample has to be preloaded by force. The data are processed by designed electronics and recorded in a computer in a utility application, developed for this purpose. The thesis is realized in cooperation with the Centre of polymer systems of the Tomas Bata Univerzity in Zlín.

Mechanical design and realization of the concurrent magazine for yarn
Klusoň, Vladimír ; Ripel, Tomáš (referee) ; Vejlupek, Josef (advisor)
This thesis deals with a Temporaryyarn storage device for yarn produced on an industrial loom. The Temporaryyarn storage contains a driven storage drum with a rotational yarn compensor. The driven rotating storage device is coupled with the first drive supplied by an electrical motor, and the rotational compensor is coupled with a second drive- also an electrical motor. The described Temporaryyarn storage can effectively increase the level of automation of an industrial loom.

Trajectory planning for vehicle with four steering and driven wheels
Trávníček, Tomáš ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This thesis deals with trajectory planning and driving for two-wheel steering (2WS) and four-wheel steering (4WS) vehicle in environment with static obstacles. Algorithms, mentioned in the search, are used for planning the path for vehicles with front wheel steering. The kinematic model is ana-lyzed and simplified. The problem of trajectory planning is solved in Matlab using trajectory dis-cretization and searching within the state space. The implemented algorithm deals with obstacle collisions as long as the map is obtained, therefore the planning does not take so much computa-tional time. Finally, the algorithm is tested on a two-wheel minibike. The solution is applicable for variety of vehicles with additional movement possibilities, even when adapted it can deal with planning in the three dimensional workspace. The results of this thesis are applicable for planning for 2WS and 4WS vehicles.

Automatized working place for measuring of airflow parameters
Smělý, Jakub ; Vejlupek, Josef (referee) ; Vlach, Radek (advisor)
This thesis describes the design work for the measurement of air values. The first part describes the airflow, pressure build-up in pipes and losses due to airflow losses. There is also a description of fans and explain their characteristics depending on the pressure generated by airflow. The next part describes the design of the measuring chamber, electronics and control for fully automatic measurement of air quantities.

Sensory array for home automation
Bastl, Michal ; Lamberský, Vojtěch (referee) ; Vejlupek, Josef (advisor)
Bachelor thesis Sensory array for home automation describes the design of a simple system for measuring air temperature, relative humidity and light levels in the room. The aim is to design measuring units which will be able to communicate with the parent unit through the RS-485 fieldbus. Parent unit will be designed to allow the transfer of data to PC via the USB bus.

The detection of the rotation direction of a fuel pump
Matějásko, Michal ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This thesis describes the design and commissioning of a device for detection of the rotation direction of a DC fuel pump. The rotation direction is calculated on the basis of change of magnetic field during its movement. Detection of the rotation direction will be applied in manufacture at possible supply cables confusion testing. Thesis is carried out in cooperation with industrial partner.

Educating model for mechatronics: model development and fast USB communication
Formánek, Martin ; Vejlupek, Josef (referee) ; Appel, Martin (advisor)
Táto diplomová práca sa zaoberá návrhom a realizáciou výukového modelu pre študentov mechatroniky na vysokej škole. Úvod práce sa zaoberá krátkym uvedením do problematiky používania univerzálnej sériovej zbernice a jej implementáciou pre komunikáciu s mikrokontrolérom. Druhá časť je venovaná hardwaru zariadenia, medzi čo patrí voľba vhodného motoru, návrh vhodných elektronických komponentov, návrh dosiek plošných spojov a taktiež mechanickej konštrukcie celého zariadenia. Nasleduje softwarová časť, popisujúca praktickú realizáciu komunikácie, program v mikrokontroléry, a Toolbox, ktorý umožňuje užívateľovi jednoduchú interakciu s hardwarom a to jak z Matlabu. tak zo Simulinku. Kombinácia navrhnutých hardwarových a softwarových prvkov umožňuje jednoduchú cestu k zlepšeniu vedomostí študentov v oblastiach programovania, riadenia a modelovaní sústav. Pre tieto účely je práca rozšírená o pracovný list, ktorý dopĺňa navrhnuté zariadenie o sadu experimentálnych úloh, zameraných na vybrané mechatronické problémy.
