IPPA is a low cost prosthetic arm with advanced functionality and features that compare to commercial prosthetics. Our system enables the amputee to perform automated grasping tasks, perform a wide range of hand gestures, and incorporate a mobile app management system that will allow the prosthetic to be taught user specified grasps and gestures.



Automated Grasping using EMG sensor

Proximity Sensing using Distance sensor

Force Sensitive Control

Build new Gestures with Android App


In this project I lead the idea to challenge the current standard of upper-limb prosthetics, and focused on how the team and I could use our expertise in engineering and computer science to impact the quality of life for amputees.

In the ideation stage, I noticed current upper limb prosthetics are expensive and limited in their functionality. I conceived the idea to build an intelligent, programmable upper limb prosthetic that uses off-the-shelf electronic sensor and components, and can be manufactured using 3D printing. I proposed the idea to my team who liked the idea and wanted to build it. I co-devised a list of functionalities and power consumption constraints of the product, co-designed the hardware and software architecture of the product, and then co-developed a working prototype in 10 months. This project resulted in the development of a low cost upper limb prosthetic that can perform automatic grasping of objects and one-motion-gestures.

I feel that this project reflects myself strongly as an emerging media student because I participated in tackling a complex challenge of designing an intelligent prosthetic, and led my team to challenge area of social significance for amputees,their quality of life.
