Project of special manipulator
Martinů, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This thesis describes the design of a special manipulator, driven by a special mechanism with a pushed chain. The chain is conducted from the bottom branch of a horizontal guide slot via a chain wheel to the upper branch of a guide slot. To the end of the chain there is connected a frame manipulator via a tap connection. In this work there are described and suggested the most important component units of a manipulator, including a drive.

Optimization Algorithm for the Truss Steel Structures
Zeizinger, Lukáš ; Čorňák,, Štefan (referee) ; Brázda,, Robert (referee) ; Malášek, Jiří (advisor)
The work deals with the optimization of trusses construction building and transport machinery. The goal was to create an algorithm that can design an optimized design. The simulation took place on two experiments involving 52 sets of different entries, which are processed in detail into graphs. One-dimensional target mass or price function is used as part of optimization, but there is also an incorporated multidimensional purpose function. The finite element variation method for the beam system is used for the strength calculation of the truss structure and the genetic algorithm is used for optimization. At the end of the work, specific steps are formulated that lead to the most appropriate algorithm settings.
