Analysis of potential active damping for vehicles
Svoboda, Jakub ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
Diploma thesis deals with the issue of active and semi-active damping and its possible applications in the context of vehicles. The beginning of the document is focused on the actual state, major applications and patents in the field. As each of the individual ways of usage is relatively specific, the next part is aimed particularly at the damping unit of bicycle. Given the choice, real measurements and simulations were made in order to verify the applicability of such a device in practice.

Control of the Mini-Swing manipulator
Ráheľ, Dušan ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
The diploma thesis deals with control of robotic manipulators and their range of applicability. The main objective is to create kinetic model of manipulator in the SolidWorks environment and to set up the identification and control program in the LabVIEW software. It evaluates the applicability of SoftMotion Module tool, which was developed especially for the model control in Motion analysis. The proposed method of control is used on the kinetic model, which employs control commands for the movement of manipulator MiniSwing

Modeling of linear drive for control design purposes
Drábek, Jakub ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
Thesis deals with the design of control of linear drive by taking advantage of connection between tools provided by NI LabView graphical programming environment and SolidWorks 3D CAD system. This work describes the various resources the CAD systems provide for virtual modeling of mechatronic systems and their simulation. Control is designed using simulation tools by utilizing link between NI LabView and SolidWorks, while the invented control mechanism is finally tested on real system.

Operating software with web interface for programmable controllers
Matějka, Tomáš ; Kovář, Jiří (referee) ; Houška, Pavel (advisor)
This diploma thesis deals with developing of software, which allows access and control of programmable controllers through web interface. Software uses client server model and for communication between client and server is used Windows Communication Foundation interface which is integrated in Microsoft .NET Framework from version 3.0. Applications were written in C# programming language using .NET Framework libraries. Data visualization in web application was created by Microsoft Silverlight.

Modelling and control of mechatronic systems with SolidWorks and NI LabVIEW
Fridrichovský, Jan ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
When designing a Mechatronics system should be the management implemented into the mechanism of technological products. It is therefore necessary to create a connection tool for the management design and tools for the CAD of the management mechanism. The company responded that the need for the issuance of National Instruments toolkit to connect the NI LabVIEW with SolidWorks CAD tool. This link allows the NI LabVIEW environment to control the simulation on the virtual model in the SolidWorks/COSMOS Motion and back to obtain the results of dynamic analysis. The aim of this work is to evaluate the possibility of linking development tools and CAD system and evaluate its use in the design of Mechatronics system.

Oscillatory Power Generator Base on Mechanical Resonant Element
Mihalík, Vlastimil ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This work deals with the power supply of wireless sensors. When using a wireless sensor is desirable application of alternative energy sources, because the primary cells or batteries may reduce the extent or length of service of the sensor itself. Ambient energy can be used as a suitable alternative source. This energy must be in an appropriate form, which allows its conversion to electric energy. These appropriate, already used types include: solar en., temperature gradient en., en. of flowing liquids, vibration, etc. The advantage of vibrations is its presence in almost all mechanical systems. One of the possibilities for using the vibration of machine systems for power supply wireless sensors is using the vibration power generator with oscillating component. The generator must be designed so that its resonance frequency coincides with the frequency of vibration in the machine system. This method can be used only if the machinery system vibrations at least partially constant. Another option is to use the vibrations caused by, for example, transit transport, or different step acting factor. In this case, it is desirable that the generator is designed with variable resonant frequency, which can partly be achieved, for example, integrating several oscillating component in the body of generator. After the general analysis of the problem, graduation theses will be concerned with the possibility of use of energy from the short damped oscillation and step impulse. Focusing on a proposal of multi-element structures.

Design of the absolute position sensors with Hall elements
Pikula, Jiří ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
This work deals with possibilities of use of linear Hall sensors which are made as integrated circuit for construction of absolute sensors of position and rotary position. Hall sensors with permanent magnets allow a smaller construction. In this work there is described a design and solution of absolute linear sensor of position for linear drive of Stewart's platform and absolute sensors of rotary position for robotic manipulator Mini-swing. Use of these sensors adds many advantages, primary minimal size and high resolution.

Utilization of the inertial sensors for control of the mobile robots
Lachnit, Zdeněk ; Ondroušek, Vít (referee) ; Houška, Pavel (advisor)
The main subject of this thesis is use of inertial sensors for better motion and stability control of mobile robots. In background research are described the basic methods of mobile robots localization. Second part of background research is about mobile robot stability, in this part are described the methods of mobile robots stability control. In next part is description of MEMS accelerometers and gyroscopes and description of basic method of filtering and integration which are useful for input processing of these sensors. Thesis continues with inertial sensors analysis for application on control of wheeled and legged mobile robots. In end of thesis are specified the experiment results, which confirm the applicability of sensors for mobile robot control.
