Prosthetic Arm Bike Attachment

This project was completed with three of my peers my senior year of high school. Our engineering teacher was approached by a parent asking for help with improving her daughter's prosthetic arm. Her daughter was experiencing neck soreness every time she rode her bike due to having to lean to one side to help herself balance. We developed an attachment for a bike handle that her daughter could then attach her prosthetic arm to. 
The design process started on Solidworks, where we designed multiple prototypes. We then 3D-printed the designs and tested them for efficiency. After testing out the prototypes we made a new optimized design, which was then created using precision machining techniques.
The most important feature of the final design was a component that allowed for rotation of the arm, which made it easier to turn the bike. Without this feature it was hard for the bike handles to turn without losing balance. Another important feature was the screw style adjustment that will allow for the attachment to be lengthened as the daughter grows.
