    Abstract: A two-stage accumulator based pneumatic supply architecture (TAPSA) is provided for rapid actuation of multiple compliant pneumatic actuators simultaneously for their potential applications in wearable robotic assistive and rehabilitative devices, serving as light-weight and untethered actuation systems. The TAPSA comprises Polyethylene Terephthalate (PET) bottles serving as primary accumulators and secondary accumulators connected in series. Individual targeted levels of pneumatic pressures are achieved in actuators of the TAPSA within targeted durations of time for the rapid actuation of the actuators by the action of Pulse Width Modulation (PWM) controlled solenoid valves supplying pressurized air from the secondary accumulators which are in turn pressurized in prior to predetermined levels based on system performance model developed by a data driven approach utilized in the TAPSA. Rejuvenation of pressure in the secondary accumulators occurs through a pressure feedback based PD control scheme executed in between consecutive actuation cycles.

    Abstract: An accumulator for a hydraulic system includes a polymer liner defining a cavity. A metal bellows assembly is housed in the cavity and separates the cavity into a first chamber and a second chamber, with the first and second chambers isolated from one another by the bellows assembly. A composite shell substantially encases the liner. The liner and shell are configured so that the first chamber receives hydraulic fluid from and delivers hydraulic fluid through an opening in the liner and the shell as the bellows assembly expands and compresses due to pressurized gas in the second chamber balancing fluid pressure changes in the first chamber. In one embodiment, the metal bellows assembly includes hydroformed bellows.
