Abstract
A robotic ankle system provides an assistive force for the heel-up portion of a user gait. Energy is stored in a spring responsive to a heel-on portion of the gait, and then released as the heel-up portion begins. In this manner, the gait of a user is assisted. The systems and methods are of particular use for those affected by stroke or in connection with rehabilitation activities.
