Design of an industrial robot with six degrees of freedom
Štefek, Ondřej ; Štěpánek, Vojtěch (referee) ; Knoflíček, Radek (advisor)
The diploma thesis deals with the design, production and construction of robots with six degrees of freedom and a serial kinematic structure. In the beginning of the thesis, the individual types of robots, used gearboxes, energy media are described, and the principle of direct and inverse robot kinematics is outlined here. In the next chapters, the system approach of the robot, the selection of the optimal variant of creation, and then the kinematics and dynamics of the robot, which further follows on from the principle of the creation of castings, the design nodes of the robot and its electrical engineering and the programming of the control system, are analyzed. For the pinions and the shaft of the fifth axis, a safety analysis is carried out with respect to the limit state of elasticity. This robot design is then financially compared with a commercially available industrial robot. For the robot, among other appendices, drawing documentation, an electrical wiring diagram and a safety analysis of the robotic workplace have been prepared. The robot and the related robotic workplace are physically built in the workshops of the Institute of Production Machines, Systems and Robotics in Brno.

DESIGN AND APLICATION OF COLLABORATION ROBOTS ACCORDING OF I4.0
Salaj, Jakub ; Szabari, Mikuláš (referee) ; Knoflíček, Radek (advisor)
Presented bachelor’s thesis deals with collaborative robots and their application in manufacturing with a focus on the implementation of Industry 4.0 principles. In the theoretical part of the thesis, a system analysis of the robotization of production processes by collaborative robots was carried out, as well as a system analysis of cobots as a technological system and the requirements that are set by the relevant standards for their safe operation. In the literature review, a range of design solutions offered by three major manufacturers of cobots and end effectors were demonstrated. The main research objective was to describe successful implementations in practical manufacturing applications. A sub-objective of this thesis was to evaluate the cobot workplace in the context of Industry 4.0. The evaluated workplace was a station for measuring the electric resistance of the fuel-filter during its production, whose operation was described and evaluated by means of a SWOT analysis. In the conclusion of the thesis, based on the obtained findings, an overall evaluation of the monitored issue and recommendations for its further development were formulated.

Optimizing the production process by assembling high-pressure pumps
Hotovec, Václav ; Knoflíček, Radek (referee) ; Szabari, Mikuláš (advisor)
This bachelor's thesis focuses on optimizing the assembly process of pumps at Bosch Powertrain s.r.o. The introductory theoretical section provides a brief description of topics related to the content of the thesis, including the characteristics of robotic workstations and the application of industrial robots in engineering. Based on the provided data, the production process is first analyzed, and then the selection of a weak point for detailed research and optimization is justified. According to the requirements, the objectives of the optimization and the constraints that must be respected in the solution design are outlined. Two solutions are proposed, dealing with modifications to the existing robotic workstations, aiming to reduce the production cycle time and limit manual intervention in the process. From these solutions, a suitable one is selected based on multi-criteria analysis, simulated using Tecnomatix Process Simulate, and economically evaluated. The result of this work is design solution for optimizing, its economic evaluation and simulation.

Design of a special effector for autonomous robot
Med, Slavomír ; Knoflíček, Radek (referee) ; Pavlík, Jan (advisor)
This master’s thesis deals with the design of a specialized end effector for an autonomous robot capable of collecting plant samples from plant leaves. The theoretical part describes the classification of industrial manipulators, their end effectors, and briefly outlines plant research. Plant research is the specific application area for this end effector. Based on a review of available solutions, several conceptual variants are proposed, and the best one is selected using multicriteria analysis. This concept is tested and further developed until its final form. Subsequently, calculations are performed for the pneumatic circuit of the end effector, and safety requirements are outlined. The conclusion of the thesis includes an economic evaluation of the entire end effector, project assessment, and recommendations for further steps.

Virtual commissioning of robotic loading of workpieces into the machine tool
Grünwaldová, Kristýna ; Knoflíček, Radek (referee) ; Vetiška, Jan (advisor)
This thesis deals with virtual commissioning of the manipulation station using a robot, while it is a replacement of a workplace that was originally operated by employees. The aim is to make production more efficient by means of robotic loading of workpieces into the machine tool. The thesis describes a sequence of stages that lead to the virtual commissioning of the robotized workpiece placement in the RobotStudio program so that the workplace can be automated. First, it was necessary to design a new concept for the original workplace, then to create this concept in the RobotStudio program, and then to operate the individual elements of the entire workplace and to create a sequence of actions connected to each other as it would be during real operation. In the thesis the connection with the real workplace was not considered, the workplace was put into operation only virtually.
