Prosthetic Foot

GEAR Lab is working with Bhagwan Mahaveer Viklang Sahayata Samiti (BMVSS) to design an updated version of their Jaipur Foot, which is the most widely distributed prosthetic foot in the world. The original Jaipur Foot’s success was due to its lifelike look, flexibility, and extreme durability. We aim to create a new version of the foot that is much lighter, can be mass-manufactured, meets international testing standards, is compatible with other prosthetic equipment, and matches the durability of the current foot. We developed a novel prosthetic foot design objective called the Lower Leg Trajectory Error (LLTE) based on the biomechanical performance of healthy feet and on the insight we gained interacting with BMVSS. Using this objective, we are optimizing the compliance and geometry of our prosthetic foot to deliver lifelike gait mechanics using low-cost materials.
