The Optimum Design of a Vacuum-Compatible Manipulator to Calibrate Space Based Ultraviolet Imagers

Grillo, Jason L. 01 January 2020 (has links)
Recent discoveries in geospace science have necessitated the design of compact UV imaging instruments to make space-based observations from multiple vantage points. The miniaturized ultraviolet imager (MUVI) instrument from the Space Sciences Laboratory (SSL) at UC Berkeley is under development to facilitate such discoveries on a wider scale. This thesis documents the design, integration, and characterization of a vacuum compatible manipulator to calibrate the MUVI instrument inside the UV thermal vacuum chamber at SSL. Precision linear and rotation stages were implemented with custom mounting plates to achieve four degrees of freedom. Optical components were installed to imitate the MUVI instrument for testing purposes. A customized PCB was fabricated to control the stages and receive position feedback data. A Graphical User Interface was programmed and utilized to position the manipulator during experimental validation. Field of View sweeps were conducted using visible light and a monochromatic CMOS sensor to track the coordinates of a laser's centroid. An analytical model of the optics assembly was developed and later refined from the experimental results. Using this model, the translation stages successfully compensated for optical misalignments. Analysis of the performance data showed the pointing resolution of the manipulator was less than 1 arcmin, which satisfied the calibration requirement for the MUVI imager.

Manipulátor se vzorky plechů pro mechanické zkoušky / Manipulator with sheet metal samples for mechanical tests

Glogar, Matěj January 2010 (has links)
This thesis deals with a solution of lifting equipment for sheet metal samples handling. Facility will be part of an automatic production line for semi-finished test specimens for testing the mechanical properties of sheet metals. The options of solutions discussed in this thesis is performed that choice which should be the concept of lifting equipment. Course work cycle of the selected concept is designed, so that material flow provided by the facility meets requirements of the production line. Calculations for the design parts of the main cylinder and the running gear are carried out using a set of parameters and then strength check of steel construction follows. The 3D model of the manipulator, the manipulator assembly drawings and layout drawings of the production line are annexes of this work.
