The Development of the New Concept of Autonomous Cranes
Kubín, Martin ; Knoflíček, Radek (referee) ; Hrabovský, Leopold (referee) ; Škopán, Miroslav (advisor)
The presented PhD thesis aims to verify the possibilities of using capacitive accelerate sensors on the crane and handling technology. Capacitive acceleration sensors of MEMS type are currently widely used in electronics, e.g. laptops and mobile phones. Using these sensors could help to automate cranes, which would eventually reduce the financial costs of material handling. Precise knowledge of their own condition and position of the machine and the load is a necessary part of autonomous manipulators. The first part of thesis deals with the exploration of scientific research in the Czech Republic and abroad. Furthermore the options of mathematical description of moving the load on the rope tow are described including solved examples. One chapter is devoted to the description of sensors that could be used in the automation of cranes. The main part is focused on description of several experiments. The experiments were conducted in a lab constructed specially for this measurement. Mainly basic simpler models are described illustrating abilities of the sensor. The last part outlines further possible progress of research in this area.
Design and implementation of testing device for specimen mechanism for electron microscope
Trnkócy, Tomáš ; Radoš, Jiří (referee) ; Krejsa, Jiří (advisor)
Práce se zabývá návrhem a implementací testovacího zařízení pro manipulačnínmechanismus vzorku v elektronovém mikroskopu. Testovací zařízení a jeho software zajištuje meření několika parametrů mechanismu, jejich statistické vyhodnocení a porovnání se specifikací. Cílem je vytvořit komplexní testovací zařízení s jednoduchým uživatelským rozhraním, s požadavkem náhrady stávajícího nemodulárního a nestabilního řešení a jeho rozšíření o testování dalších parametrů.
