Classification: CPC B  F | IPC F

Claim 1:
2. The apparatus of claim 1, comprising:
a second pressurized chamber including a second aperture to intake a second fluid;
a second eversion-based actuator in the plurality of eversion-based actuators including a second reel of material expandable upon intaking the second fluid;
a third valve coupled to the second pressurized chamber and connecting the second pressurized chamber to a third pressure source via the second aperture,
upon activation, the first valve to enable intake of the fluid into the pressurized chamber;

a fourth valve coupled to the second pressurized chamber and connecting the second pressurized chamber to a fourth pressure source via the second aperture,
a pressure of the second fluid in the third pressure source exceeding a pressure of the second fluid in the fourth pressure source,
upon activation, the fourth valve to enable outflow of the second fluid from the second pressurized chamber;

a second passive retraction system exerting a second retraction force on the second reel of material causing the second reel of material to shorten when the second retraction force exceeds a second expansionary force exerted by the second fluid in the second pressurized chamber; and
a processor to independently control lengthening and shortening of the reel of material and lengthening and shortening of the second reel of material.
