Classification: CPC B  F | IPC F

Claim 9:
10. The apparatus of claim 6, wherein the activation mechanism comprises:
a shaft bidirectionally rotatable around an axis;
a clutch selectively coupling the reel of material to the shaft,
the clutch to allow free rotation of the shaft relative to the reel when the rotation of the reel is blocked,
the clutch to allow rotational coupling between the reel of material and the shaft when the shaft is rotated in a first direction and the reel is free to rotate thereby expanding the reel of material when the shaft rotates in the first direction and the clutch rotationally couples the reel of material to the shaft, and
the clutch to allow rotational coupling of the reel of material and the shaft when the shaft is rotated in a second direction and the reel is free to rotate, thereby contracting the reel of material when the shaft rotates in the second direction; and

a motor connected to the shaft, the motor to bidirectionally rotate the shaft around the axis,
operation of the motor rotating the shaft in the first direction to simultaneously expand a first multiplicity of eversion-based actuators in the plurality of eversion-based actuators.
