Abstract:

The goal is to design the Spring Ankle with Regenerative Kinetics SPARKy which seeks to develop a new generation of powered prosthetic devices based on the Robotic Tendon actuator. This actuator is a lightweight motor and transmission in series with a helical spring that significantly minimizes the peak power requirement of an electric motor and total system energy. The Robotic Tendon has kinetic advantages and stores and releases energy to provide SPARKy users with 100 of required push-off power and ankle range of motion comparable to able-bodied ankle motion while maintaining a form factor that is portable to the wearer. The objective is to build a transtibial prosthesis that will support a Military amputees return to active duty.
