Pvcrov : An Experimental Platform For Multi-Robot Control Systems, Nicholas Prince, Gregory Roos, Jennifer Semones, Chase Traficanti
Pvcrov : An Experimental Platform For Multi-Robot Control Systems, Nicholas Prince, Gregory Roos, Jennifer Semones, Chase Traficanti
Mechanical Engineering Senior Theses
As the field of multi-robot control systems grows, the demand for flexible, robust and precise multi-robot testbeds increases. Up to this point, the testbeds that do exist for testing multi-robot controllers are often expensive, hard to deploy, and typically constrained to a single plane of motion. These constraints limit the capacity to conduct research which is why team Autonomously Controlled Electromechanical Systems (ACES) has created the PVCROV system. PVCROV is a low cost, underwater platform for testing multi-robot control systems. By utilizing an underwater environment, ACES created a testbed that is not constrained to a single plane of motion. Additionally, …

Formula Electric : Powertrain, Mark Allison, Bryan Bidwell, Stuart Hopson, Jackson Smith, Carlos Streegan, Dominic Villa
Interdisciplinary Design Senior Theses
The Santa Clara Formula Electric team designed, and manufactured a powertrain for an electric racecar according to the rules prescribed by the SAE International Formula Electric competition. The powertrain is divided into subsystems: the battery pack, battery pack cooling system, motor controller, and the motor. The battery pack was constructed, but full electrical connection of all cells were not made. The pack was not integrated with the motor and motor controller. In addition, due to time constraints, extensive testing could not be completed.
Project Omoverhi : Low-Cost, Neonatal Incubator, Richard Fong, Guillermo Gallardo, William Jeffery, Danny Maeda, Gabriel Romero
Project Omoverhi : Low-Cost, Neonatal Incubator, Richard Fong, Guillermo Gallardo, William Jeffery, Danny Maeda, Gabriel Romero
Interdisciplinary Design Senior Theses
Project Omoverhi, since its beginning in 2010-2011, has been focused on creating an incubator that has the capability of operating completely off grid. This year the project has been focused on redesigning the original system to reduce the cost to approximately $1000. In addition to this we have designed and implemented a control system that enables the user to set a desired temperature which can be maintained to within 1 degree Celsius. Before the project is able to be completed further work must be done. The thermal storage system that was initially proposed by the original team still needs to …
Mechanics Of Bolted Electrical Splices, Samuel Alberts
Mechanics Of Bolted Electrical Splices, Samuel Alberts
Theses and Dissertations
Localized heating of bolted electrical splices in the power distributing bus is a primary concern in the industrial automation industry. While localized heat generation problems are commonly reported in the field, it is not entirely clear what the root causes are. A methodology is presented for development of a tool to measure in-situ the influence of clamping load on the thermo-electric behavior of the splice joint. Applied research and reasoning used to identify probable root causes for failures reported in the field are also presented. Experiments were conducted to characterize the mechanical properties of the bolt and nut system used …

The success of laser and electron beam-based fabrication processes for additive manufacture and repair applications requires the ability to control melt pool geometry while maintaining a consistent and desirable microstructure. Previous work has employed a process map approach to link melt pool geometry to solidification microstructure (grain-size and morphology) in beam-based fabrication of Ti-6Al-4V. The current work extends the approach to investigate the effects of process variables on solid-state phase transformations below the solidification temperature through Finite Element Modeling, the 3-D Rosenthal Solution, and experimentation. Process maps for solid-state microstructure could be used to help maintain consistent and reliable mechanical …
