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 Nov 2019

#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 ...


Automated Portable Bandsaw, Josh Redmond, Pt Ketchem, Jonathan Lybrand, Aaron Mcclellan Nov 2019

Automated Portable Bandsaw, Josh Redmond, Pt Ketchem, Jonathan Lybrand, Aaron Mcclellan

Georgia Undergraduate Research Conference (GURC)

This report proposal and progress report will cover the design of an automated mounting station for a portable bandsaw for the Mechanical Engineering Senior Design course at the Marietta campus of Kennesaw State University. The idea behind this mounting station is for it to provide a more cost-effective alternative to other automated cross-cutting systems, while also providing more accurate and precise cuts into different metals and minimizing operator error and material waste. The purpose of this proposal is to add the mobility of having a portable bandsaw with the precise cutting of a mounted bandsaw, but while minimizing the cost ...


Machine Learning For Designing Stretchable Carbon Nanostructures, Helena Hepler, James Clarkston Nov 2019

Machine Learning For Designing Stretchable Carbon Nanostructures, Helena Hepler, James Clarkston

Georgia Undergraduate Research Conference (GURC)

In this research study, we employ machine learning algorithms to perform molecular dynamics simulations for graphene-like 3D carbon nanostructures. Custom MATLAB programs and Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) are used to conduct the simulations in this report. The results obtained in this research will accelerate the development of more advanced nanomaterials such as 3D carbon nanostructures by improving the accuracy of the simulations of their material properties.


On Software Development For Generating The Profile Of The Cut For Tube Notching, Austin Marak, Eric Nzuki, Simin Nasseri Nov 2019

On Software Development For Generating The Profile Of The Cut For Tube Notching, Austin Marak, Eric Nzuki, Simin Nasseri

Georgia Undergraduate Research Conference (GURC)

The intent of this project is to design a novel Tube Notch software to produce the trajectory of the cut for notching two tubes at a specific angle. A fool-proof MATLAB Graphical User Interface (GUI) was designed to read the critical input values for tube notching and generate the G-code and accurately scaled PDF templates.

The tube notch software allows the user to enter the joint and torch parameters such as angle of fit, the outer diameters of the uncut and cut tubes, the wall thickness of the cut tube, surface speed, and pierce dwell for the plasma torch in ...

Senior Design 1 Product Proposal, Chase Newberry, John Redwine

Georgia Undergraduate Research Conference (GURC)

People have climbed for millennia, but only in recent years has rock climbing acquired recognition as a legitimate sport. Modern rock-climbing culture is centralized on pushing one’s limits to the extreme. As such, falling is an eventuality for those seeking a challenge. Luckily, falling is not a death sentence for the modern climber. Protective equipment has advanced in parallel with human ability, and fall-arresting gear is now widely available to the public.

One of the most popular types of protective climbing gear is the cam (figure 1). As they are now manufactured by numerous companies, cams designs vary, but ...
