Claim 11:
12. The apparatus of claim 6, comprising:
a shaft bidirectionally rotatable around an axis;
a first clutch selectively coupling a first eversion-based actuator in the plurality of eversion-based actuators to the shaft, the first clutch to:
the first clutch to allow free rotation of the shaft relative to the first reel when the rotation of the first reel is blocked,
the first clutch to allow rotational coupling between the first reel of material and the shaft when the shaft is rotated in a first direction and the first reel is free to rotate thereby expanding the first reel of material when the shaft rotates in the first direction and the first clutch rotationally couples the first reel of material to the shaft, and
the first clutch to allow rotational coupling of the first reel of material and the shaft when the shaft is rotated in a second direction and the first reel is free to rotate, thereby contracting the first reel of material when the shaft rotates in the second direction;

a first brake coupled to the first reel of material associated with the first eversion-based actuator, operation of the first brake to include a first mode and a second mode,
the first mode to disengage the first brake from the reel of material, allowing the reel of material to rotate, and
the second mode to engage the first brake with the reel of material, preventing the reel of material from rotating;

a second clutch selectively coupling a second eversion-based actuator in the plurality of eversion-based actuators to the shaft, the second clutch to:
the second clutch to allow free rotation of the shaft relative to the second reel when the rotation of the second reel is blocked,
the second clutch to allow rotational coupling between the second reel of material and the shaft when the shaft is rotated in a first direction and the second reel is free to rotate thereby expanding the second reel of material when the shaft rotates in the first direction and the second clutch rotationally couples the second reel of material to the shaft, and
the second clutch to allow rotational coupling of the second reel of material and the shaft when the shaft is rotated in a second direction and the second reel is free to rotate, thereby contracting the second reel of material when the shaft rotates in the second direction; and

a second brake coupled to the second reel of material associated with the second eversion-based actuator, operation of the second brake to include a first mode and a second mode,
the first mode to disengage the second brake from the reel of material, allowing the reel of material to rotate, and
the second mode to engage the second brake with the reel of material, preventing the reel of material from rotating.
