An articulating mechanism comprises a first link, a second link, an intermediate portion, a first hinge between the first link and the intermediate portion, and a second hinge between the second link and the intermediate portion. The first link, the second link, the intermediate portion, the first hinge, and the second hinge are integrally formed. The articulating mechanism also comprises a plurality of cables for rotating the first and second links about the first and second hinges. The cables extend through channels in the first link and the second link without extending through the intermediate portion. The first and second hinges are oriented parallel to each other to permit the first and second links to rotate in the same plane about the first and second hinges, respectively. The first and second links are rotatable about the first and second hinges in two directions under control of the cables.

1. An articulating mechanism comprising: a first link;a second link;an intermediate portion, the intermediate portion including two stem sections;a first hinge between the first link and the intermediate portion;a second hinge between the second link and the intermediate portion, wherein the first link, the second link, the intermediate portion, the first hinge, and the second hinge are integrally formed, and the first hinge and second hinge are coupled by the two stem sections; anda plurality of cables for rotating the first and second links about the first and second hinges, the cables extending through channels in the first link and the second link without extending through the intermediate portion,wherein the first and second hinges are oriented parallel to each other to permit the first and second links to rotate in the same plane about the first and second hinges, respectively, andwherein the first and second links are rotatable about the first and second hinges in two directions under control of the cables. 2. The articulating mechanism of claim 1, wherein a combined distance between exit points for channels on opposing faces of the first link and the second link remains constant as the first link and the second link rotate about the first hinge and the second hinge. 3. The articulating mechanism of claim 1, further comprising a central channel. 4. The articulating mechanism of claim 1, further comprising one or more wing sections disposed between the first link and the second link. 5. The articulating mechanism of claim 4, wherein the intermediate portion comprises the one or more wing sections. 6. The articulating mechanism of claim 4, further comprising an outer cover and an inner core, wherein the outer cover comprises the first link, the second link, the intermediate portion, the first hinge, and the second hinge and wherein the inner core comprises the one or more wing sections, wherein the one or more wing sections are positioned within the intermediate portion of the outer cover. 7. The articulating mechanism of claim 4, wherein the one or more wing sections limit a range of rotation for at least one of the first link and the second link. 8. The articulating mechanism of claim 1, wherein a range of rotation of each of the first and second links is substantially the same in the two directions. 9. The articulating mechanism of claim 1, wherein at least one of the first and second hinges is positioned relative to the first link and the second link to provide a neutral pull bias for the cables. 10. The articulating mechanism of claim 1, wherein at least one of the first and second hinges is positioned relative to the first link and the second link to provide a negative pull bias for the cables. 11. The articulating mechanism of claim 1, wherein at least one of the first and second hinges is positioned relative to the first link and the second link to provide a positive pull bias for the cables. 12. An articulating mechanism comprising: a first link;a second link;an intermediate portion;a first hinge between the first link and the intermediate portion;a second hinge between the second link and the intermediate portion, wherein the first link, the second link, the intermediate portion, the first hinge, and the second hinge are integrally formed;a plurality of cables for rotating the first and second links about the first and second hinges, the cables extending through channels in the first link and the second link without extending through the intermediate portion;one or more wing sections disposed between the first link and the second link;an outer cover and an inner core, wherein the outer cover comprises the first link, the second link, the intermediate portion, the first hinge, and the second hinge, and wherein the inner core comprises the one or more wing sections, wherein the one or more wing sections are positioned within the intermediate portion of the outer cover,wherein the first and second hinges are oriented parallel to each other to permit the first and second links to rotate in the same plane about the first and second hinges, respectively, andwherein the first and second links are rotatable about the first and second hinges in two directions under control of the cables. 13. The articulating mechanism of claim 12, wherein a combined distance between exit points for channels on opposing faces of the first link and the second link remains constant as the first link and the second link rotate about the first hinge and the second hinge. 14. The articulating mechanism of claim 12, further comprising a central channel. 15. The articulating mechanism of claim 12, wherein the one or more wing sections limit a range of rotation for at least one of the first link and the second link. 16. The articulating mechanism of claim 12, wherein at least one of the first and second hinges is positioned relative to the first link and the second link to provide a neutral pull bias for the cables. 17. The articulating mechanism of claim 12, wherein at least one of the first and second hinges is positioned relative to the first link and the second link to provide a negative pull bias for the cables or a positive pull bias for the cables. 18. The articulating mechanism of claim 12, further comprising: an alignment flange protruding from the inner core; andan alignment slot extending into an interior surface of the outer cover, the alignment slot configured to receive the alignment flange protruding from the inner core. 19. The articulating mechanism of claim 12, further comprising a plurality of cable slots extending lengthwise along the interior surface of outer cover, wherein an interior surface of the cable slots is formed by an exterior surface of the inner core.
