Claim 11:
12. A system comprising:
an actuator base;
at least two bimorph actuators comprising at least a first bimorph actuator disposed at the actuator base oriented in a first direction and a second bimorph actuator disposed at the actuator base oriented in a second direction perpendicular to the first direction, each of the at least two bimorph actuators comprising:
a shape memory alloy material; and
a beam, wherein each of the at least two bimorph actuators is attached to the actuator base at a first end of the beam, a second end of the beam opposite the first end configured to be unfixed;

a moving carriage coupled to the at least two bimorph actuators; and
a second actuator engaged to the moving carriage, the second actuator configured to move in a positive z-direction, the second actuator comprising:
a pair of buckle arms; and
a second shape memory alloy material coupled with the pair of buckle arms at opposing ends of the pair of buckle arms, each of the opposing ends of the pair of buckle arms coupled with the actuator base, ends opposite the opposing ends of each buckle arm of the pair of buckle arms configured to move in the positive z-direction.
