9. A motor comprising:
-
a substrate; a cantilevered lever arm mounted, by a first end, on the substrate; a shape-memory transducer acting on the cantilevered lever arm wherein movement of the transducer deflects the cantilevered lever arm; a latch; and second end of the cantilevered lever arm which engages the latch to thereby release the latch when the transducer is activated.

10. A motor comprising:
-
a substrate; a cantilevered lever arm mounted, by a first end, on the substrate; a shape-memory transducer acting on the cantilevered lever arm wherein movement of the transducer deflects the cantilevered lever arm; an electrically conductive strip attached to the substrate; a plurality of electrically conductive elements attached to the substrate adjacent to the strip; and a wiper arm attached to the crank wherein the wiper arm bridges the strip and the elements to complete an electrical circuit with the shape-memory transducer to thereby move the crank to a preselected position.
