Hydraulic linear drive for paralell kinematics structures of robots
Petruška, Bohumil ; Kubela, Tomáš (referee) ; Knoflíček, Radek (advisor)
This thesis deals with new construction of hydraulic linear drive for paralell kinematics structures of robots. In the first section provides a historical development of robots with this structures. There are also described differences between each machine with this structures and compares them with machines with linear structures. In the second section is made a proposal of hydraulic actuator. Designed actuators are arranged into hexapod. There is also included a proposal of possible solutions to fixing hydraulic actuator to platform and base. This thesis include drawings of selected parts and drawing of a whole set of new designed hydraulic actuator. It is included a block diagram of the hydraulic circuit.

Experimental robotized workplace with delta-robot
Kozubík, Jiří ; Holub, Michal (referee) ; Knoflíček, Radek (advisor)
This diploma thesis was written within Czech-German study programme Production systems (VUT v Brně & TU Chemnitz). This thesis is divided into four main parts. In the first part is brought out the introduction to design of robotic cells. Following part is concentrated on analysis of present state in area of machines with parallel kinematics. The penultimate part, on which is focused the main attention, is dedicated to kinematic analysis of delta-robot. Closing part of this Thesis presents the study of experimental robotized workplace with integrated delta-robot.

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.

Increasing the level of automation of the company's production processes
Horák, Michal ; Knoflíček, Radek (referee) ; Blecha, Radim (advisor)
The aim of this work is to create a methodology for creating a strategy to increase the level of automation of manufacturing process. Based on the customer´s requirements, management of manufacturing company, the concept of methodology was developed. The research and design of the necessary tools and procedures to evaluate the feasibility of automation were subsequently carried out. Based on the outputs from the feasibility analysis, rules for the formulation of the automation strategy were established. The method was subsequently applied to the process of the manufacturing company for which an analysis of the feasibility of automation was carried out. Subsequently, recommendations were made for further steps to increase the level of automation, thus proposing a strategy for the company. The methodology created is applicable to companies with discrete batch production that do not have defined the automation strategy yet.

Design of walking mobile robot
Szabari, Mikuláš ; Knoflíček, Radek (referee) ; Kočiš, Petr (advisor)
The diploma thesis deals with the construction of a walking mobile robot, which is intended for passing through a rugged or forest terrain, whose task is to collect the sample. The first part is devoted to the review of walking robots. Follow-up an analysis of two-legged and four-leg walking robot technologies and a brief overview of drives. The second part is devoted to problem analysis and design variant. The work contains 4 design variants in the form of schemes. Using the multi-criteria analysis, the variants were evaluated and the optimal variant was chosen taking into account the representative parameters. The third part is devoted to the construction of the chosen variant, it is divided into body and leg construction. The overall design is processed in the form of a virtual 3D model. In the leg construction, the design itself, but also the calculations of drives, shafts, gears and belt transmissions are solved. The end of the thesis is devoted to drawing documentation based on 3D model and economic evaluation. Follow-up and discussion with possible continuation and use in practice.

Roll assembly system for automatic strapping
Havelka, Michal ; Marek, Tomáš (referee) ; Knoflíček, Radek (advisor)
This bachelor’s thesis is dealing with the design of system for rolls of technical textiles, which assembles them into horizontal layer. Possible structural drafts are mentioned here and one selected draft is solved. For the first I am dealing with major dimensions, the choice of rollers, calculation of the required engine power and the calculation of the chain drive. Finally I calculated pneumatic cylinders and checked the deflection of used rollers.

Design of a stent shaping unit
Václavek, Marek ; Vetiška, Jan (referee) ; Knoflíček, Radek (advisor)
The goal of this thesis is to create a design of a single-purpose machine used to shape thin plastic tubes with the use of thermal processes. The thesis first focuses on research of industrial robots, which will be used as a basis for the selection of handling equipment performing key tasks within the machine. Based on the results of a multicriteria selection method, the selected industrial robot model is Epson VT6L. The following manufacturing processes were proposed according to the analysis of the reuirements: heating with the use of heating cartridges, cooling with water-cooled clamps and chilling in a refrigeration chamber with conveyors. The proposed techniques were formulated into a detailed design solution. A simulation of the robotic tasks was conducted in order to verify the trajectories of the robot and to estimate the cycle time of machine. The machine was assessed from the aspect of work safety and measures were proposed for selected sources of hazards.
