Robotic cell design for automated manipulation - expedition of beer barrels and bottle crates
Slováček, Adam ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
From the begining the shipping line is described and explained together with used principles. Requarements are set for the design of the industrial robot. A suitable industrial robot is selected. The propeties of the robot are described and location is being solved. The construction of existing effector which is going to go through improvement is descibed. In the controls are given the basic conections of sections and overview functioning. The basic standarts of safety are included as well as security of the workplace and possible problems that may occure during the operation of the line.

Design of a device enabling the reconnection of a glider to a towing aircraft
Ryba, Filip ; Löffelmann, František (referee) ; Sklenář, Filip (advisor)
This bachelor thesis deals with the design of a two-part system for connecting a glider and a towing aircraft in the air. The theoretical part deals with a summary of the principles of glider functions and an analysis of the reconnection attempt. The practical part discusses the proposed parts of the concepts that could fulfil the function and their combination forms into a final design solution. The solution is displayed in the drawing documentation and verified by manual and FEM calculations.

Advanced Magnesium Alloys Surface Modification by Ni-P Based Coatings
Kosár, Petr ; Pacal, Bohumil (referee) ; Nový,, František (referee) ; Havlica, Jaromír (advisor)
The dissertation thesis deals with the modification of the surface of advanced magnesium alloys with Ni-P based coatings. At the beginning of the theoretical part, the structures of the used magnesium alloys and the influence of individual alloying elements on their properties are characterized. In the following part of the thesis the current knowledge in the field of electroless deposition on metal substrates is summarized. The theoretical part of the thesis is closed with contemporary research study in the field of clarification and determination of possible mechanism of electroless deposition. For the subsequent investigation of the mechanism of electroless deposition on magnesium alloys, it was necessary to characterize the microstructure and composition of individual magnesium alloys in the first phase of the experimental part. The exact composition of elements was determined using glow discharge optical emission spectroscopy and scanning electron microscopy with EDS was used for composition of phases of magnesium alloys. Using scanning electron microscopy and detailed elemental analysis of the coated magnesium substrate, it was found that for optimal Ni-P coating deposition on magnesium alloys, acid pickling prior coating is required in a mixture of acetic acid and sodium nitrate. Using the XPS method, it was found that the phosphorus atom in the sodium dihydride-diphosphate reducing agent has a + V charge. 4 At the end of the experimental part scanning electron microscopy and detailed elemental analyses were used for monitoring of the Ni-P particles nucleation and growth in the first 120 seconds of the coating process.

Construction of boom of loader Dapper
Gregor, Jiří ; Petráš, Jiří (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the analysis of the current kinematic mechanism of the DAPPER 5000 boom. The second part of the thesis deals with the new mechanism design. The new solution is also analysed kinematically and forcefully. The first part of the thesis is devoted to a description of the DAPPER 5000 and its parts. It is followed by a description of its boom, its analysis and comparison with the booms of competitive loaders. After a critical review of the various boom concepts, where their suitability for the DAPPER 5000 is assessed, a new mechanism for the DAPPER boom is designed. This is followed by a detailed analysis of this mechanism, a basic strength check and, in conclusion, the results of the analyses are summarized, and the meaningfulness of this structural change is evaluated.

Industrial robot application in area machinning technology
Staněk, Michal ; Matějka, Petr (referee) ; Knoflíček, Radek (advisor)
This study analyzes the application of industrial robots and manipulators in the area of cutting. It portrays the evolution of this dynamic sector and its next possible advancement. It explains the basic categorization and division of industrial robots and manipulators (IRM). The author offers an overview of various applications of IRM, with typical examples of the correct use of different types in technological processes (turning, milling, grinding etc.) in order to effectively increase the production. The study also describes two robotized technological work sites that the author personally visited and documented in detail. This study is supposed to show the indisputable advantages of employing the automating elements into the mechanical engineering and to explain the basic concept of this industry.

Evaluation of Corrosion on Selected Magnesium Alloys
Pořický, Vladislav ; Tulka,, Jaromír (referee) ; Pacal, Bohumil (advisor)
This master´s thesis is focused on classification of corrosion resistivity magnesium alloy type AZ91 in environment of salt vapour testing in corrosion chambers. For tests were used samples of magnesium alloy manufactured by three different methods of casting: cast-iron mold, die vacuum casting, die casting without vacuum and method of die casting with additional pressure (squeeze casting). In this work was accomplished metallographic evaluation of corrosion attack and detailed analysis of corrosion products. Conclusions of exposits tests are assembled of analysis of influence of corrosion environment on structure of alloy. On the basis of these conclusions of corrosion tests were evaluated influences of corrosion speed [mm/year] on time [hours] for individual states of magnesium alloy.

Arrangement of Piston for BMW 2,5 TDS 4-stroke CI-engine
Rada, Lubomír ; Drápal, Lubomír (referee) ; Svída, David (advisor)
In this bechelor work presentation and design a four-stroke piston diesel engine with direct injection diesel by 130 kW, which is used in BMW vehicles. When choosing key dimensions come out of the original dimensions of the piston, used in diesel engine with indirect injection into the vortex chamber 105 kW of power. The draft of the main dimensions of the piston followed by strength calculation of the critical points of the piston.
