Project 3a: Prosthetics for percussion


This initiative has been developed to address the distinct requirements of a young woman traversing her middle school journey while confronting the obstacles presented by bilateral amputation. With extreme attention to detail, our primary goal is to create a prosthetic arm, precisely engineered to enable her participation in percussion activities with a seamless blend of refinement and skill. Through this endeavor, our aim extends beyond mere functionality; we aspire to instill within her a profound sense of empowerment, fostering the confidence and grace necessary to fully embrace her passion for percussion.

Problem Statement

The client we have been paired with is a middle school girl who is a bilateral amputee. She is in a band class and wants to fully participate in percussion. Our challenge is to create a prosthetic arm that has an attachment for a drumstick, is comfortable, and durable.

Background Research

As of recent, prosthetic arms have been evolving to account for recent technological advancements. However, with this project being conducted by amateur engineers, researching this topic consisted of looking at materials for the arm and simplistic ways to effectively accomplish our lofty goals. To start with materials

Concept Design 1

The rough idea for the sleeve is to have a function that tightens as a nob is twisted as seen in the sketched picture below. This should also be made of a flexible printing material that is more skin-safe.

Concept Design 2

The main inspiration comes from a “Hero Arm” design seen below. The idea would be to securely hold the drumsticks, look aesthetically pleasing, and remain comfortable/safe throughout any performance/practice.

Concept Design 3

The idea for the main device/mechanism is to provide a secure way to hold multiple styles of drumsticks and fit comfortably on the arm of the client. Since both arms are developed differently (one arm not having the elbow joint), two different assemblies are required. Both versions are displayed in the image provided along with a potential idea for the stick-clamp.
