The Problem:
Many stroke survivors, elderly people and disabled individuals experience challenges with mobility, especially their fine motor movements, impacting their daily activities and quality of life. Current rehabilitation solutions are bulky, expensive, and not easily accessible for use outside of doctor care. To address this issue, my focus is on designing a low-cost and portable exoskeleton to assist individuals with fine motor recovery to regain and strengthen their mobility.
How Can We Address This?

Principles of Design
The CAD model is made by extruding and modifying 2Ds shapes including different forms of lines, circles, ovals, and irregular shapes (such as the servo holder)
The final model is a 3D object made from geometric shapes
The end product will have a pla finish, giving it a smooth texture
The repetitive arrangement of the circular rings shows a pattern.
The rings are also made of 2 different sizes- showing both symmetry among the similar sizes and asymmetry among the different sizes
Although there are different parts, they all come together to serve one purpose- increasing hand mobility and thus showing harmony
Developing this design initially strengthened my CAD skills my completing tutorials in basic fusion tools: fillet, evolve, chamfer, and shell. By the end, I used these skills to create complex parts of my design, making the process smoother and more efficient. However, after receiving feedback, my second iteration incorporated an even more efficient design.

Looking into the Future:
This project is rooted in empathy-driven innovation, addressing the needs of the user. However, in the future, adding an Arduino circuit to the finger exoskeleton would increase its functionality and allow for individual testing. The adaptability and customizability of this design make prosthetics and future exoskeletons more affordable for individuals by leveraging existing technologies.
