Georgia Undergraduate Research Conference (GURC)

Title: Human-Machine Interactions Using a Flex-Sensor And 3D Printed Robot Arm

Abstract

We developed a flex-sensor based glove system that can be used to tele-operate a 3D printed humanoid arm (Langevin, 2014). The glove and arm are interconnected through an Arduino based microcontroller which has been programmed to collect sensor data from the glove and to control individual fingers of the 3D printed arm. We present our initial study in understanding the reliability and feasibility of human interfacing with the electro-mechanical arm. Using this system, we plan to understand and quantify biomimetic finger movement. The flex-sensor data captured by the ...


#31 - Muscle Fatigue And Recuperation With Inclusion Of Vibration Plate, Cody Scarborough Nov 2019

#31 - Muscle Fatigue And Recuperation With Inclusion Of Vibration Plate, Cody Scarborough

Georgia Undergraduate Research Conference (GURC)

Surface Electromyography, or sEMG, measures the electrical activity of muscles. These measurements can be used to show the difference between muscles at rest and during activity. Active muscles do not have to be in motion but can be flexed as when pulling on an immovable object. Over time, as the muscles are flexed and active, they will begin to fatigue. This fatigue can be directly measured with the sEMG sensors. If the immovable object was a handle attached to a force plate, then the force of this pulling could be measured also.

Our proposal is to measure the correlation of ...


Design And Kinematic Analysis Of A Semi-Compliant Swashplate Mechanism, Niko Giannakakos Nov 2019

Design And Kinematic Analysis Of A Semi-Compliant Swashplate Mechanism, Niko Giannakakos

Georgia Undergraduate Research Conference (GURC)

Compliant mechanisms generate motion through the deformation or deflection of its flexible members rather than the revolute joints utilized in traditional rigid link mechanisms. If a compliant mechanism is designed as a single piece without the need of joints to create relative motion, then it is a monolithic system. If at least one part of the mechanism is flexible and assembled with rigid parts and joints, then it is a partially compliant mechanism. The superiorities of compliant mechanisms over rigid mechanisms are the reduced number of parts required to build the system, simple design, no backlash, no lubrication, less friction ...


Fundamental Design Of Submarine Communication Buoy With Oceanic Condition Considerations, Alex Resnick, Katherine Mitchell, Hannah M. Maier, Muhammad Salman Nov 2019

Fundamental Design Of Submarine Communication Buoy With Oceanic Condition Considerations, Alex Resnick, Katherine Mitchell, Hannah M. Maier, Muhammad Salman

Georgia Undergraduate Research Conference (GURC)

Communication with active United States Navy submarines is often difficult while the submarines are in active operation. Submarines must float close to the surface of the ocean, at a depth of less than thirty meters, to engage in heavy communication with command operations. When a submarine is on a mission; however, the submarine will operate at depths of one-hundred meters or greater, and significant communication is limited. A solution to this communication limitation includes the use of very-low or extremely-low frequency transmissions. Transfer of information is at a rate of 8 bytes/second, so only basic encrypted text can be ...

#49 - Optimization Redesign Of Cargo Ship Hopper, Carson Wiles, Rafael Escamilla, Max James Ryan, Juan Bautista

Georgia Undergraduate Research Conference (GURC)

There are current designs of hoppers that are sitting on the port where cargo ships enter. The ships have large crane buckets that move material from the ship to dump trucks by means of funnel. The top portion of this funnel is a hopper that calls for a redesign. Some main dilemmas with the hopper are that it is easily damaged by the crane bucket, gives off a lot of dust debris, and is difficult to mobilize. Our project redesign looks to add a stronger support hopper that is resistant to damage and a dust ventilation system that reduces dust ...


Design Of A Monolithic Compliant Swimming Robot, Joshua Hooper, Andy Houghton Nov 2019

Design Of A Monolithic Compliant Swimming Robot, Joshua Hooper, Andy Houghton

Georgia Undergraduate Research Conference (GURC)

Compliant mechanisms use the flexibility of their members to transfer an input displacement, force or torque to another point on the mechanism through the large deformation of its flexible links or joints. Fewer number of links, no friction, no backlash and simple design are the most important features that make them an ideal candidate when light weight, low cost and high performance are desired. The only challenge while designing a compliant mechanism is deriving the equations of motion as flexible links or flexure hinges go under large deformation.

We designed a monolithic compliant swimming robot consists of a dc motor ...

Directional Spectrum Measurements By The Spotter: A New Developed Wave Buoy, Kaus Raghukumar, Grace Chang, Frank Spada, Tim Jannsen

Ocean Waves Workshop

The Spotter is an accurate, low-cost, easily deployable and robust solar powered wave buoy recently developed by Sofar Technologies (formerly Spoondrift). Spotter reduces costs and complexity of surface wave and current measurements, which can be useful for academic, military, and commercial research into surface wave and wave-driven dynamics. We performed a series of validation tests and research experiments with the Spoondrift Spotter. The low-cost and compact Spotter makes it easy to deploy arrays of wave buoys which was previously not feasible (or cost prohibitive) with traditional wave buoys. A well-designed array can provide a direct measurement of the directional wave ...

Innovations In Metocean Sensors, Pieter Smit, T. T. Janssen

Ocean Waves Workshop

Real-time observations are critical to understand, predict and estimate the impact of extreme weather events such as extratropical hurricanes and storms. Remote sensing, moored wave buoys and advances in predictive models have greatly advanced understanding and predictive capability of extreme ocean weather. However, due to cost and complexity of traditional moored buoys, in-situ networks are typically sparse and often close to shore and not well suited to drive predictive models over meaningful geophysical scales. Here we will discuss ongoing efforts to extend the capability of the Sofar Spotter to measure marine boundary layer dynamics. With the advancement to more portable ...

Achieving Energy Justice In Low Income Communities: Creating A Community-Driven Program For Residential Energy Savings, Anya Galli Robertson, Kevin Hallinan, Jennifer Hoody

Conference: The Social Practice of Human Rights

The cost of residential energy the U.S. is unequally distributed, with low income households paying higher rates and spending 16.8% of their income on utility bills compared to 3.5% of all U.S. Residents.[1] Researchers have found that bringing the housing stock up to the efficiency of the median household would reduce excess energy cost by as much as 68%.[2] However, access to opportunities to reduce residential energy consumption and costs such as tax incentives and utility rebate programs tends to be biased toward wealthier, white homeowners. Additionally, low income residents are most likely to ...


The Effect Of Radial Head Hemiarthroplasty Stem Fit On Radiocapitellar Contact Mechanics: Is Loose Fit Better Than Rigidly Fixed?, Jakub Szmit, Graham J.W. King, James A. Johnson, G. Daniel G. Langohr Jun 2019

The Effect Of Radial Head Hemiarthroplasty Stem Fit On Radiocapitellar Contact Mechanics: Is Loose Fit Better Than Rigidly Fixed?, Jakub Szmit, Graham J.W. King, James A. Johnson, G. Daniel G. Langohr

Western Research Forum

Background/Methods: Radial head hemiarthroplasty is commonly employed to manage comminuted displaced fractures. With regards to implant fixation, current designs vary with some prostheses aiming to achieve a tight 'fixed' fit, and others utilizing a smooth stem with an over reamed 'loose' fit. The purpose of the present study was to evaluate the effect of radial head hemiarthroplasty stem fit on radiocapitellar contact using a finite element model which simulated both fixed (size-for-size) and loose (1, 2 & 3mm over reamed) stem fits.

Hypothesis: It was hypothesized that a loose stem fit would improve radiocapitellar contact mechanics, with increased contact area ...


Investigating The Effect Of Stiffness In Hemiarthroplasty Implants, Carolyn Berkmortel, Daniel Langohr, Graham King, James Johnson Jun 2019

Investigating The Effect Of Stiffness In Hemiarthroplasty Implants, Carolyn Berkmortel, Daniel Langohr, Graham King, James Johnson

Western Research Forum

Background: Hemiarthroplasty is an attractive alternative to total arthroplasty because it conserves tissue, allows for quicker recovery, and has a lower cost. However, likely due to the high stiffness of the implant, hemiarthroplasties often lead to accelerated wear of the opposing native cartilage.

Hypothesis and Methods: The purpose of this study was to investigate the maximum contact stress on the capitellum for different currently available biomaterials in radial head hemiarthroplasty and compare them to the native radial head. A finite element model was developed in ABAQUS (Dassault Systèmes Simulia Corp., RI, USA). An axial load of 100N was applied to ...

High Resolution Validation Of Next Generation Turbulent Flow Models Using Neutron Beams, Laser Fluorescence, And Cryogenic Helium, Landen G Mcdonald May 2019

High Resolution Validation Of Next Generation Turbulent Flow Models Using Neutron Beams, Laser Fluorescence, And Cryogenic Helium, Landen G Mcdonald

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Turbulent fluid flow is an incredibly unpredictable subject that continues to confound scientists and engineers. All of the empirical data that has been the basis of conventional turbulent computational fluid dynamics (CFD) models for decades only extends to roughly the equivalent turbulence created when Michael Phelps swims in a pool. The problem is that this data is then extrapolated out many orders of magnitude in order to design cruise ships, airplanes, and rockets which operate in significantly more turbulent flow regimes. This creates an incredible degree of uncertainty in the design process that demands over-engineering and increased expenditures.

The development ...

Geospatial Energy Potential And Life Cycle Assessment Of Nearshore Oscillating Water Column Systems, Aleks Siemenn, Marie-Odile Fortier

CURCE Annual Undergraduate Conference

Oscillating Water Column (OWC) systems are an iteration of terminator ocean energy technology which generate electrical energy from turbine torque induced by the compression of air in a chamber from changing water level height. OWCs are a well-established technology, however, there have been no studies to date which quantify the life cycle environmental impacts of these systems in a geographic context. The goal of this study is to optimally size an OWC system for selected New England coastline sites and then assess the environmental impacts of the varying system sizes.

An OWC system is optimally sized when the volume of ...

Layered wicks enable passive transport of condensation out of cooling systems

Nhicolas Aponte, Jordan Morrow, Gennifer Riley, Partha Chakraborty, Melanie M. Derby

Department of Mechanical and Nuclear Engineering, Kansas State University

Cooling systems, like condensers or cooling towers of a power plant, transfer heat out of a system. The cooling process often occurs through the condensation of water, which forms a liquid film that reduces heat transfer. This problem makes cooling systems larger and more costly. One approach to this problem is drop-wise condensation in which condensed water gathers in the form of droplets which can then run off, preventing ...

BACKGROUND

Hand osteoarthritis (H-OA) is the most common type of osteoarthritis largely affecting individuals over 45. H-OA involves pain, loss of grip strength and limiting participation in recreational activities such as golf. Currently, a number of ‘arthritic’ grips are designed using joint protection principles to ‘reduce hand forces and tight gripping’. However, no comprehensive examinations in their effectiveness have been conducted.

HYPOTHESIS

The purpose of this study is to systematically analyse the hand forces produced from various golf grips and arthritis grips at the distal-phalanges of the hand-grip interface in individuals with and without hand arthritis using new wearable sensor ...
