The Da Vinci Robotic Instrument Control via Microcontroller
Pivoňka, Václav ; Kopečný, Lukáš (referee) ; Sekora, Jiří (advisor)
The main objective of this thesis was to design the drive and select a microcontroller for motion control instruments operating Da Vinci robot. In addition to design flowchart for the microcontroller program to administer the robotic arm using servo-motor, steering servo-motor circuit solution microcontroller. The work also includes a block diagram, flowchart program and the draft circuitry.
Scanning photoelasticimetry
Šikula, Radek ; Palai-Dany, Tomáš (referee) ; Škarvada, Pavel (advisor)
This thesis deals with the polarization of the light and its use in the field of photoelasticity measurement. The theoretical part is divided into two sections. First the light is described as electromagnetic waves in the theoretical section. Further the polarization types are described and the principle of the photoelasticity is explained. Electronic is described in the second section of the theoretical part. In the frame of the experimental part electronic design is presented together with the program for the scanning device controller. The functionality of the device is tested in the last section.
Construction of an opto-mechanical system for continuous adjusting of the LIBS-laser power
Pořízka, Pavel ; Brillová, Kateřina (referee) ; Kaiser, Jozef (advisor)
The purpose of bachelor thesis is construction of opto-mechanical system for regulation of intensity of Nd:YAG laser used in LIBS aparature. Intensity of laser is regulated via rotating of second polarizer to the first one. Polarizer is rotated around axis of laser beam by stepper motor. Stepper motor is connected to driver unit and operated by computer. Necessary number of steps of stepper motor is accomplished by usage of cog wheels transmission.
