Yeager Multifunctional Tool

A group of motivated Cal Poly senior engineering students are designing and building an easy to use, low cost, and durable multi-functional hand tool for people who have severely limited or no use of their hands or wrists. This ergonomically designed tool will allow those with upper extremity limitations to use a variety of interchangeable hand tools useful for daily tasks, leading to more independence and an improved quality of life. Their goal is to have a working prototype that is ready for production by the end of Cal Poly’s Spring Quarter 2017.

Self-Powered Ankle Prosthetic

Cal Poly senior engineering students are designing and building a durable self-powered prosthetic ankle that provides ankle biomechanics similar to an active prosthetic while retaining the simple use and design of a passive prosthetic.  The proposed design will have no external power and will attach to a below the knee prosthetic for amputees who want to live an active and independent life.  The end goal by June 2017 is to prototype an ankle that better mimics the musculature of a normal ankle and restores 80% of the range of motion. This will improve quality of life by allowing the user to function on uneven terrain in various environments with minimum energy input.

Prosthetic Leg Modification

Dedicated Cal Poly senior engineering students are designing and prototyping an adjustable below the knee prosthetic leg to provide a Navy SEAL amputee, with a means of meeting his mission safely and effectively.  He currently carries two additional prosthetic legs during his deployments and has requested a multifunctional prosthetic to improve his quality of life while still acting as an effective member on his team. The Prosthetic Leg Modification project involves combining the functions of walking, running, and swimming into a durable, lightweight, waterproof, and comfortable below the knee prosthetic that will not slip off.  The students’ goal is to have a working prototype by the end of Cal Poly’s Spring Quarter 2017.

Prosthetic Socket Cooling System

A team of Cal Poly senior engineering students are designing and building a system that will dissipate the heat created inside the socket of a leg prosthetic.  This will allow amputees to perform physical activity without creating excessive sweat inside their sockets.  Losing a limb reduces the body’s ability to prevent overheating and will cause increased perspiration, especially during activity.  Although this challenge was presented by Taylor, a Navy explosive ordinance disposal technician who lost all four limbs, this product will also serve as a practical solution for any active amputee.  The students’ goal is to have a working prototype by the end of Cal Poly’s Spring Quarter 2017.
