Lightweight Deployment Mechanism Of Solar Arrays For Use In Cubesats, John Wood Ellis

Undergraduate Honors Capstone Projects

Cube satellites, also referred to as CubeSats, were developed in the late twentieth century, and have since served as a cost-effective method of gathering out-of-this-world data. The development of these small-scale satellites have helped universities and small companies worldwide to perform important experiments, as well as gather critical data in order to provide for further space exploration. Cube satellites are designed to be self-sustaining, by using solar cells to capture impinging thermal energy and convert it to power to be consumed by the electronics housed within the satellite itself. In order to function properly, these cells are extended in an …

Design For Reduction Of Noise Produced By Natural Gas Regulator, Britany L. Chamberlain

Undergraduate Honors Capstone Projects

This document describes the design of a multi-stage restrictive orifice device (MSRO) that serves to reduce the noise produced by a regulator valve. The scope of this document explains the determination of the proper design through the development of analytical models, the design of a test fixture to obtain empirical data, and the corroboration of the models with empirical data to obtain a working solution.

Smart Carabiner, Craig Manning

Undergraduate Honors Capstone Projects

Users of common climbing safety equipment rarely understand exactly the loads and forces they are exerting on the equipment at a given time. All climbing equipment comes with a certified safety rating for the amount of force, in kilonewtons, that particular piece of equipment can take. Unfortunately, calculating dynamic load strain on-the-fly is nearly impossible. There needs to be a reliable, easy way of knowing exactly what load is being placed on a piece of equipment at any given point of time.

Mimicking Robotic Backhoe, Taylor Chad Bybee

Undergraduate Honors Capstone Projects

The proposed project is to design and create a small robotic arm that mimics movements of a similar physical model. The manual model can be manipulated by a human. Sensors inside the manual model will detect the position in each part of the arm. The information from the sensors will then be relayed, processed, and forwarded to the mimicking model. The mimicking robotic model will appropriately respond to match the smaller model, thus mimicking its position and movements.

Right Hand Fork Pedestrian Bridge Final Report, Ren Gibbons

Undergraduate Honors Capstone Projects

Right Hand Fork is a tributary canyon whose stream enters the Logan River nine miles east of the mouth of Logan Canyon near Logan, Utah. The access bridge to a popular recreational area, the Hobbit Caves, was damaged in 2011 by flooding. We propose that a new bridge be designed and constructed for the Forest Service to replace the current structure to ensure public safety and minimize environmental impact. We plan to use a longer bridge span that will situate the abutments higher on the stream bank and reduce possible water damage during flood events. Bridge costs will be minimized …

Lateral Control Of A Vehicle Platoon, Samuel A. Mitchell

Undergraduate Honors Capstone Projects

Multiple lateral control systems are analyzed for use in a vehicle platoon system. In order to ensure the safety of the vehicle platoon, the system must operate under three constraints: (1) accurate path following, (2) string stability, and (3) functionality in the presence of noise. Computer simulations are employed to analyze candidates according to the safety requirements. Actual vehicle kinematics and nonlinearities - limits on turn radius, velocity, and acceleration - are included in this analysis.

Successful control system candidates are implemented in a platoon of five differential-steer vehicles. The sensing and communication requirements of the control system are discussed. …

Binding Innovation Technologies, Restoring Freedom To The World Of Snowboard Bindings, Matthew Lee Munsee

Undergraduate Honors Capstone Projects

Snowboarding technology has progressed by leaps and bounds since the sport's inception in the 1980's. However, there is one area that has gotten progressively worse. That area is flexibility and freedom of expression. In order to make the sport safer, the industry responded by making stiffer boots and bindings. Our goal is to bring back the high level of flexibility that built the sport while maintaining or exceeding current safety standards. We also need to reduce heel side shock so as to increase the comfort of the rider. Our design consists of three major systems that drastically increase flexibility, safety, …

Smart Laboratory Instrument Control Framework, Kevin Scott Kennedy

Undergraduate Honors Capstone Projects

The collection of experimental results in power electronic research requires the coordination of a wide variety of laboratory instrument. Depending on the type of results required, each data point can take a few minutes to collect. This process becomes time consuming when a large number of data points is needed and detracts from long-term research objectives. While there are industry standards that specify communication with these devices, many equipment vendors elect not to follow the standards and use their own protocols for communication. This project provides a framework for developing a smart and connected lab. This includes hardware and software …
