This year was an overall success. I started with an idea and I executed to my potential for the year. I am so happy with what I have completed. Looking back, I could not have completed what I did without outside help. I had Oliver Grayson help with some programming problems and mechanical construction (soldering), Oliver Weixing Nie and George Donev guide me through the 3D modeling and scaling for 3D prints, and Billy Mahoney (Database Specialist at CFHT) helped me through it all. I interned with Billy at Canada France Hawaii Telescope since mid-October and I have learned an immense amount. Just to name a few things: he taught me about arrays and different ways to incorporate problem-solving within my code, we worked on my soldering skills, designing integrated circuits, and baking solutions for creating circuits. I want to extend my greatest gratitude to him, Dr. Bill, and Mr. Halstead for everything they have done for me and my project while supporting me through my greatest dilemmas. Next year, I will work with Emalia Higgins on this project so she too can pass it on when I graduate. Next year I will pick up the project and start research with the Emotiv headset. I will begin working on making my Bionic Prosthetic Hand controlled by brainwaves. I must note that although I had some major challenges this year, I would not have changed the experience. Every bump on the road taught me something new and was essential to my end of the year success. Below are my 2016-17 (#1) and 2017-18 (#2) project proposals:

ISR Proposal - Naibryf
“You think therefore you can.”
I am making a Bionic Prosthetic Hand that is completely 3D printed and is controlled by brainwaves for a transradial Amputee (amputation below the elbow). This upper extremity will give the user complete dexterity/range of motion for about 1/1000 the price of a regular robotic prosthesis. My goal is to make my prosthetic accessible to all in need. In the 2016-17 year, I completely 3D printed, coded, and put together an initial prototype that is controlled by a mimic hand with flex sensors. The goal for the 2017-18 year is to control the hand with the Emotiv Brainwave headset. My motto has been “You think therefore you can” and now I will truly try to think to make the hand move (can).
Abstract:
This is the Bionic Prosthetic Hand Project that is made of 3D Printed Material and gives the user complete mobility of all fingers and joints in the bio-hand at an affordable cost.
Introduction and Goals:
Growing up in an environment of doctors and engineers, I acquired a passion for making a difference in lives through technology. After reading articles on the modern day prosthetics, it amazed me how expensive, heavy, and how little mobility they gave the user. I want my project to change the life an amputee or someone born with malformation of a hand. It is my goal to be able to give back his or her hand back using modern technology.
Implementation and Challenges:
The primary goal is to have the hand completely controlled with the EEG Brainwave Headset. Using keystrokes and the new open platform that Emotiv and Arduino have set up, developers (including myself) will be able to have more functionality over the data from the headset. The most obvious challenge here is truly being able to control the each individual finger as if it was your own. Collecting data and analyzing patterns, is one of the biggest reasons I have recruited Emalia (Emi) Higgins to work with me. Apart from taking my project on after I graduate, she will learn the basics of code, 3D modeling and printing, and overall robotics. I plan to teach her everything she needs to know as well as complete the goal of finishing the prosthetic by May of 2018.
Impact and Legacy:
One might think that the most obvious projected outcome will be a fully functional bionic limb that will help other, which is true, but I want to make it a goal of mine to finish the project not only sharing this wonderful creation but learning about the technology behind it. I like to say that there is never enough research about a certain topic because there is always room to learn. I know that this project will throw some curveballs and set me back but I am hoping to improve my knowledge and skills in areas like programming where I see myself as a beginner.

-
Comfortability

Attached with synthetic skins with stiffness variations
-
Where the body is stiff, the synthetic body should be soft

And vice versa

Acetone (110C) to make it look glossy and realistic

-
Nintendo power glove
-
Flex sensors that act as potentiometers
-
Finger angle to the servo for robotic hand
-
Gest (the exoskeleton glove as I like to call it)
-
Electrical: How it communicates with the body (nervous system)
-
Cortical Homunculus
-
is a neurological "map" of the anatomical divisions of the body
-
There are two types of cortical homunculus;
-
Sensory
-
Motor
-
Both fall under electrical, mechanical, and dynamic due to characteristics
-
Syntouch and tactile sensing (sensor technology)
-
Without this, the prosthetic is just like a numb hand/fingers
-
No feeling, sensitivity

Easton LeChappele created his own robotic prosthetic hand controlled by brainwaves. I refer to his blog for some help occasionally.

This video explains the main interfaces of prosthetics.

This site explains the mapping from the way connections in the brain are ordered and arranged. I specifically focused on the writing about the motor cortex (what we use to control our bodies).

Using the developer toolkit, I will create the brain computer interface.

Prosthetics:
“You think therefore you can”
Abstract: This is the Bionic Prosthetic Hand Project that will be made of 3D Printed Material, giving the user complete mobility of all fingers and joints in the biohand.
Background and Purpose: Growing up in an environment of doctors and engineers, I acquired a passion for making a difference in lives through technology. After reading articles on the modern day prosthetics, it amazed me how expensive, heavy, and how little mobility they gave the user. I want my project to change the life an amputee or someone born with malformation of a hand. It is my goal to be able to give back his or her hand back using modern technology.
Overview: In this small timeframe, I will dedicate my time toward printing, assembling, coding, and researching what will be the final product, a bionic prosthetic. I believe that printing and assembling the hand will be the easiest portion of the project, but making it come to life is another step forward. I will make two uses out of the hand: The primary goal is to have the hand completely controlled with the EEG Brainwave Headset, and followed by my second goal of creating a mimic glove in which the controller is a glove fitted with flex-sensors which allow the hand to follow the glove’s exact movements.
Outcome/impact: One might think that the most obvious projected outcome will be a fully functional bionic limb that will help other, which is true, but I want to make it a goal of mine to finish the project not only sharing this wonderful creation but learning about the technology behind it. I like to say that there is never enough research about a certain topic because there is always room to learn. I know that this project will throw some curveballs and set me back but I am hoping to improve my knowledge and skills in areas like programming where I see myself as a beginner.
Below is an outline with additional information about bionic limbs, some tools I will need in order to accomplish both primary and secondary goals, and how to make the prosthetic as real as possible.
