Project Starfish Exoskeleton

• 

  Exoskeleton joint model

Inspiration

We are currently limited to binary finger classification for our smart prosthetic hand, and require a better means of acquiring angular/positional finger data

What it does

The device records voltages across potentiometers embedded in the joints of the exoskeleton, which correlates to the angle to which the finger has moved

How we built it

3D printing the mechanical model, use of novel voltage division, data is acquired and manipulated in Python

Challenges we ran into

We were unable to print the model today, and we had minor difficulties with the pin design for the exoskeleton joints

Accomplishments that we're proud of

Hypothesis seems to hold (so far), and we've made considerable progress on the 3D printable model and source code

What we learned

We have learned that this project is very viable, and will provide us with adequate input data to use

What's next for Project Starfish Exoskeleton

We will 3D print the model, integrate electronic components, and form a database of recorded angular data values
