Our Greatest Challenges

Prosthetic Leg Modification

The Challenge

Cal Poly QL+ engineering students designed and prototyped an adjustable below-the-knee prosthetic leg that combines the functions of walking, running, and swimming. The prosthetic they designed and created was durable, lightweight, waterproof, comfortable, and held on better than the original prosthetic leg.

This QL+ Challenge was created to provide a Navy SEAL amputee with the means of meeting his mission in the field so that he can continue to be a productive member of his team. It provides amputees like our Navy SEAL Challenger, the ability to convert from a walking and running leg to a swimming leg in only a few seconds, without having to carry separate prosthetics and tools.
