A resilient suction cup includes a body having an outer lip and a centrally located stem. The stem includes a substantially bell shaped stop and a plurality of expandable bellows. When the suction cup is positioned on an object, a vacuum source withdraws air from a cavity formed by the body. As the air is withdrawn by the vacuum source, the plurality of bellows collapse, and the outer lip forms a tight seal against the object. As the plurality of bellows collapse, the lower surface of the stop contacts the plurality of bellows, which further pushes against an upper surface of body, preventing the suction cup from being over-compressed while the vacuum source withdraws air from the cavity.

The apparatus of claim 7, wherein the shape memory alloy rods when in the austenite phase are parallel to the flexible rods and within the plane defined by the plurality of flexible rods. 9. The apparatus of claim 8, wherein the second side of the flexible skin defines a plurality of channels that are parallel to each of the plurality of flexible rods, and wherein each of the plurality of the shape memory alloy rods are interposed in the plurality of channels when the shape memory alloy rods are in the austenite phase. 10. The apparatus of claim 7, wherein the plane of the shape memory alloy rods is offset from the plane of the flexible rods. 11. The apparatus of claim 7, wherein plane of the shape memory alloy rods is substantially coplanar with the plane of the flexible rods. 12. The apparatus of claim 7, wherein the shape memory alloy is Nickel-Titanium based. 13. An apparatus for varying a wall skin to alter airflow over the skin, the apparatus comprising: a bridge; a combination mounting end-plate; a plurality of flexible rods arranged substantially parallel to substantially define a plane, each flexible rod having a mid-point and first and second ends and having a bridge-point between the mid-point and the second end, the first end being secured to the combination end-plate and the bridge-point being secured to the bridge structure; a mounting structure slidingly attached to the plurality of flexible rods at the second outer end; an elastomer enveloping the plurality of flexible rods between the mounting structure and the combination mounting end-plate and bonded to the mounting structure, to the bridge, and to the combination mounting end-plate to form a flexible skin that has a first side and a second side; and a plurality of shape memory alloy rods, each of the shape memory alloy rods having an austenite and a martensite phase, the plurality of shape memory alloy rods being arranged substantially parallel to substantially define a plane, the shape memory alloy rods having a mid-point and first and second ends and having a bridge-point between the mid-point and the second end, the first end being secured to the combination end-plate and the bridge-point being secured to the bridge structure, the plurality of shape memory alloy rods being contractible when heated to buckle the plurality of flexible rods and the flexible skin to alter airflow over the skin. 14. The apparatus of claim 13, wherein the shape memory alloy rods when in the austenite phase are parallel to the flexible rods and within the plane defined by the plurality of flexible rods. 15. The apparatus of claim 14, wherein the second side of the flexible skin defines a plurality of channels that are parallel to each of the plurality of flexible rods, and wherein each of the plurality of the shape memory alloy rods are interposed in the plurality of channels when the shape memory alloy rods are in the austenite phase. 16. The apparatus of claim 13, wherein the plane of the shape memory alloy rods is offset from the plane of the flexible rods. 17.
