Item Automation of C-mount lenses(2009-05) Coffey, Roger Leon; Pyeatt, Larry D.; Rushton, J. Nelson; Sinzinger, Eric D.C-mount lenses are typically used in applications in which the equipment is preset for a given application. Fixed applications are fine for many uses, but the inability to provide automated features to this series of cameras limit their use. One limitation would be for the application on a robotic system which must adjust itself due to its changing environment. This research shows that a cost effective C-mount motor controlled camera lens and a C -mount camera may be automated for applications such as autonomous vehicles or robotic applications. By designing a computer automated C-mount lens controller and custom automation software, a host system could have automated vision capability. Control techniques used for video and still cameras were developed in software to perform auto-focus and auto-exposure control of a lens. This architecture allows the use of numerous C-mount cameras and C-mount motor controlled zoom lenses.Item Standardization for intelligent detection and autonomous operation of non-structured hardware, and its application on railcar brake release operation(2015-05) Hammel, Christopher Scott; Tesar, Delbert; Ashok, PradeepkumarThis thesis introduces a standard framework for evaluating and planning for desired autonomous (or semi-autonomous) operations, then applies the framework, in detail, to the task of automating emergency brake release before rail-car decoupling. A significant hurdle to be accounted for is the lack of standardization of much of the hardware of interest in industry. Non-standardized rail car components must be formally structured as fully as possible to improve the reliability of the robotic automation. This brake release task requires either pushing or pulling a “bleed rod” that protrudes from the side of each rail car. The requirements for each step of the evaluation and planning process will be laid out in this thesis, as an example of how it should be applied to future automation tasks.
