Abstract
An actuation system for a joint includes an actuator having a piston, an articulating element coupled to the actuator that is driven by the piston to match a gait cycle of an appendage, an energy source engaged with the piston that energizes working fluid within the actuator to drive the piston and generate exhaust gas, a plurality of valves coupled to the actuator, and an exhaust gas holding element coupled to the actuator that is sized to hold a volume of the exhaust gas contained within the actuator.
