Abstract :
To provide a more independent alternative to the well established pneumatic artificial arm systems, body weight acting through small reciprocating pumps in the heels of the shoes is used as the power source for a self-contained hydraulic circuit. Energized by normal walking, hydraulic fluid is drawn from a flexible reservoir and delivered at high pressure to an hydraulic accumulator.
