PowerFoot One
iWalk is proud to announce PowerFoot One, the world's first actively powered prosthetic ankle and foot.
A completely self-contained robotic system, PowerFoot One is the culmination of years of research in
biomechanics, bio-energetics, materials science and joint control. Two powerful microprocessors and
six environmental sensors evaluate and adjust ankle position, stiffness, damping and power thousands of times
a second. Control algorithms generate human-like force while traversing level ground, slopes and stairs,
providing active amputees with near-normal gait and lower energy expenditure compared to state-of-the-art
passive prosthetics.
PowerFoot One is based on years of research at MIT's Media Lab, partially funded by the Veterans Adminstration and
the US Army's Telemedicine and Advanced Technology Research Center (TATRC). iWalk, created in August 2006, licensed core
technologies from MIT to create commercially available human augmentation devices, starting with the PowerFoot One.
