Finding A Viable Neural Network Architecture For Use With Upper Limb Prosthetics, Maxwell Lavin
Finding A Viable Neural Network Architecture For Use With Upper Limb Prosthetics, Maxwell Lavin
Master of Science in Computer Science Theses
This paper attempts to answer the question of if it’s possible to produce a simple, quick, and accurate neural network for the use in upper-limb prosthetics. Through the implementation of convolutional and artificial neural networks and feature extraction on electromyographic data different possible architectures are examined with regards to processing time, complexity, and accuracy. It is found that the most accurate architecture is a multi-entry categorical cross entropy convolutional neural network with 100% accuracy. The issue is that it is also the slowest method requiring 9 minutes to run. The next best method found was a single-entry binary cross entropy …
How Degrees Of Freedom Affects Sense Of Agency, Akima Connelly, Jungsu Pak, Tian Lan, Uri Maoz
How Degrees Of Freedom Affects Sense Of Agency, Akima Connelly, Jungsu Pak, Tian Lan, Uri Maoz
Student Scholar Symposium Abstracts and Posters
Can the rubber-hand illusion be extended to a moving robotic arm in different degrees of freedom (DOF), inducing sense of ownership & agency over the arm? We hypothesize that DOF closer to what humans possess will result in a stronger sense of ownership and agency.
Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin
Improving 3d Printed Prosthetics With Sensors And Motors, Rachel Zarin
Honors Projects
A 3D printed hand and arm prosthetic was created from the idea of adding bionic elements while keeping the cost low. It was designed based on existing models, desired functions, and materials available. A tilt sensor keeps the hand level, two motors move the wrist in two different directions, a limit switch signals the fingers to open and close, and another motor helps open and close the fingers. All sensors and motors were built on a circuit board, programmed using an Arduino, and powered by a battery. Other supporting materials include metal brackets, screws, guitar strings, elastic bands, small clamps, …
An Arm And A Leg: Medtech Perspectives On Human-Centered Design, Evan D. Poff
An Arm And A Leg: Medtech Perspectives On Human-Centered Design, Evan D. Poff
Marriott Student Review
The art of human-centered design accounts for both technological and emotional specifications in order to deliver meaningful products that meet the specific needs of the individual customer. Every business professional can deepen his or her understanding of human-centered design – regardless of our industry of choice – by looking to perspectives that the business of medical technology offers. To that end, this article draws upon interviews with three figures in this remarkable field, distilling their insights on how to cultivate businesses that produce human-centered solutions.
Wavelet-Eigen Analysis For Customizable Flexion Classifier Based On Electromyography Signals, Luke S. Bonnen
Wavelet-Eigen Analysis For Customizable Flexion Classifier Based On Electromyography Signals, Luke S. Bonnen
Graduate Research Theses & Dissertations
This research will cover Electromyography (EMG) and its use in prosthetics. There are many upper limb amputees that use EMG to control a prosthetic limb. While many of these prostheses are proportionally controlled, meaning they can control one movement proportional to the EMG amplitude, there is a continual need to improve function for quality of life. Proportional control is traditionally utilized for opening and closing of the hand. It is the desire of engineers to find ways to add more functionality without sacrificing reliability. There are systems that do these additional actions, but they have difficulty with reliability because of …
Developing A Testing Instrument To Evaluate The Performance Of 3d-Printed Body-Powered Prosthetic Hands, Araz Al-Dawoodi
Developing A Testing Instrument To Evaluate The Performance Of 3d-Printed Body-Powered Prosthetic Hands, Araz Al-Dawoodi
All Graduate Theses, Dissertations, and Other Capstone Projects
A 3D printed prosthetic hand is an open source technology that became a good substitution for many products in the market. For many reasons, Low-cost, easy made / easy build. As an open source product, 3D printed prosthetic designs are available to anyone around the world, a good option for young children because they need to have a new prosthetic more frequent until they reach the adulthood age. Most families cannot pay a thousand dollars technology. From the research, it found that that there are not enough studies cover the open source wrist body-powered prosthetic. Other studies covered products used …
