Inspiration

Prosthetics are extremely expensive. It is unrealistic for most families to continuously buy prosthetics for their children because they continue to outgrow them. Our project offers an affordable prosthetic that can be molded in the future, or even recreated at much lesser cost.

What it does

Our prosthetic hand has the ability to form a fist, touch the thumb and the middle finger, wave side-to-side or up-and-down, and can grasp objects. It is responsive in real time.

How we built it

We 3D printed every independently moving part of the hand and replicated the function of tendons using wire. We provide communication between the Arduino micro-controller and the Unity application, written in C#, which acquires gesture information by using the MYO.

Challenges we encountered

We struggled with time as a whole. In particular, we struggled in developing an ECG based gesture detection system. It was also tricky putting all of the pieces of the hand together and programming the server.

Accomplishments that we're proud of

Incorporating Unity and having it communicate and control the Arduino. We are also proud of designing and printing the functioning hand.

What we learned

-How to use an oscilloscope -circuit design -Unity -Working with a MYO

What's next for Prosthetic Hand

-Designing a more realistic looking hand -More precise posing of individual fingers -Finding a way to incorporate the prosthetic hand in Oculus Riff
