Design of a remote-controlled handling truck for transporting material in production
Hurtík, Daniel ; Pavlík, Jan (referee) ; Huzlík, Rostislav (advisor)
This diploma thesis deals with the design and construction of a remote-controlled handling cart for transporting material in production with a maximum total weight of 1,000 kg. The first area is devoted to the current state of knowledge and research in the field of handling carts used for material transport as well as for other applications. Furthermore, in the second part, a system analysis follows, where the important parameters that will have to be observed during the design are listed. In the third area, the proposed solution variants are specified in more detail and the winning variant for all important components and systems is specified according to the calculation procedures. The fourth part is devoted to the calculation and design of essential components, so that they are correctly selected or sized. The next part of the work focuses on the chosen electrical equipment and construction design. The sixth area of work is devoted to the economic evaluation of the developed model against the competitive solution and the last area of work deals with the final evaluation and use in practice.

Design of a small universal grinder for sharpening tools
Grym, Filip ; Huzlík, Rostislav (referee) ; Pavlík, Jan (advisor)
This thesis deals with the design of a small universal grinder for tool sharpening. The thesis begins with an introduction to the issue of tool sharpening, drilling, milling, and turning. Further, a market research and analysis of user needs is conducted. Based on these findings, several different variants of devices and methods for grinding are proposed, from which one is selected. Based on the selected variant, a 3D model and drawing documentation of selected nodes are developed. The functionality of the design is verified by basic calculations.

Virtual commissioning of a robotic welding workplace
Provazník, Adam ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This bachelor thesis is focused on the design of a robotic welding cell, a clamping fixture for a given component and subsequent virtual commissioning of the workplace. In the theoretical part is examined a current knowledge of industrial automation and robotics, as well as MIG welding method. An analysis of the clamping fixture and workplace, and a summary of the main aspects for their design are carried out furthermore. In the practical part are designed 3D models based on the previous analysis. A control program is created for these models and the workplace is virtually commissioned.

Extruder design for special 3D printing
Šedý, Karel ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
The bachelor thesis deals with a design and construction of an extruder for 3D printing of ceramic clay. The author aims to find a simple method of assembly and cleaning of the extruder. In the introduction of the bachelor thesis, the reader is briefly introduced to the history of 3D printing. Furthermore, the thesis examines 3D printing and ceramic clay, including its types, properties, and suitability for 3D printing. In the following chapters, possible problems with ceramic clay printing and how to avoid these problems are described. A multi-criteria analysis including key parameters and their weights was used to select a suitable design option. The final chapter provides a detailed description of the chosen variant's construction.

Logging station for humid environments
Pavlík, Jan ; Roubal, Zdeněk (referee) ; Szabó, Zoltán (advisor)
This thesis is about the design of a meteorological station deployed in a wet environment and its construction. The station will be used for measuring meteorological instrumentation in caves, because of that the station was designed to minimize its power consumption. Firmware was designed, to allow remote control of the station. A major part of the thesis is concerned with selection and description of the sensors and components used. Near the end of the thesis the control algorithm, communication interface and construction of the device is described.
