A method may include coupling a proximal end of a first cannula to a first manipulator of a surgical system, the first manipulator being configured to remotely actuate movement of the first cannula, wherein the first cannula comprises a rigid portion disposed between the proximal end and a distal end of the first cannula, the rigid portion having a curved longitudinal axis, and coupling a proximal end of a second cannula to a second manipulator of a surgical system, the second manipulator being configured to remotely actuate movement of the second cannula, wherein the second cannula comprises a rigid portion disposed between the proximal end and a distal end of the second cannula, the rigid portion having a curved longitudinal axis. The coupling of the first and second cannulas to the respective first and second manipulators can further include positioning respective first and second centers of motion of the first and second cannulas proximate to each other, and positioning respective longitudinal axes of the first and second cannulas at the first and second centers of motion across one another.

1. A method comprising: mounting a proximal end of a first cannula to a first manipulator of a surgical system, the first manipulator being configured to remotely actuate movement of the first cannula, wherein the first cannula comprises a rigid portion disposed between the proximal end and a distal end of the first cannula, the rigid portion having a curved longitudinal axis; andmounting a proximal end of a second cannula to a second manipulator of the surgical system, the second manipulator being configured to remotely actuate movement of the second cannula, wherein the second cannula comprises a rigid portion disposed between the proximal end and a distal end of the second cannula, the rigid portion having a curved longitudinal axis;wherein the mounting of the first and second cannulas to the respective first and second manipulators comprises: positioning respective centers of motion of the first and second cannulas proximate to each other; andpositioning respective longitudinal axes of the first and second cannulas at the respective centers of motion across one another. 2. The method of claim 1, further comprising inserting the distal end of the first cannula through an opening of a patient's body, and inserting the distal end of the second cannula through the opening of the patient's body. 3. The method of claim 2, further comprising positioning the respective centers of motion of the first and second cannulas proximate the opening of the patient's body. 4. The method of claim 1, further comprising inserting the distal end of the first cannula and the distal end of the second cannula through a surgical port positioned in an opening of a patient's body. 5. The method of claim 4, further comprising positioning the respective centers of motion of the first and second cannulas in respective channels extending through the surgical port. 6. The method of claim 1, further comprising orienting the first cannula and the second cannula so as to position the respective distal ends of the first cannula and the second cannula to face toward a surgical site within a patient's body. 7. The method of claim 1, further comprising orienting the first cannula and the second cannula so as to position the respective distal ends of the first cannula and the second cannula to face toward each other. 8. The method of claim 1, further comprising advancing a first surgical instrument through the first cannula, the first surgical instrument comprising a flexible shaft and an end effector coupled to the flexible shaft. 9. The method of claim 8, wherein advancing the first surgical instrument through the first cannula comprises advancing the first surgical instrument through the first cannula until an end effector of the first surgical instrument is positioned beyond the distal end of the first cannula. 10. The method of claim 9, further comprising advancing a second surgical instrument through the second cannula, the second surgical instrument comprising a flexible shaft and an end effector. 11. The method of claim 10, wherein advancing the second surgical instrument through the second cannula comprises advancing the second surgical instrument through the second cannula until an end effector of the second surgical instrument is positioned beyond the distal end of the second cannula such that the end effector of the first surgical instrument and the end effector of the second surgical instrument are positioned for triangulation of a remote surgical site. 12. The method of claim 1, further comprising independently moving the first cannula about the center of motion of the first cannula and the second cannula about the center of motion of the second cannula. 13. The method of claim 1, further comprising moving at least one of the first cannula and the second cannula in at least one of a pitch motion and a yaw motion around a respective one of the centers of motion of the at least one first and second cannulas. 14. The method of claim 1, further comprising: mounting a proximal end of an endoscope to an endoscope manipulator of the surgical system, the endoscope manipulator being configured to remotely actuate movement of the endoscope, wherein the endoscope has a center of motion defined between the proximal end and a distal end of the endoscope;wherein the mounting of the endoscope to the endoscope manipulator comprises positioning the center of motion of the endoscope proximate to the respective centers of motion of the first cannula and the second cannula. 15. The method of claim 1, further comprising controlling the first and second manipulators to independently move the first cannula and the second cannula about the respective centers of motion of the first cannula and the second cannula. 16. A method comprising: mounting a proximal end of a first cannula to a first manipulator configured to move the first cannula as a rigid body about a first center of motion;mounting a proximal end of a second cannula to a second manipulator configured to move the second cannula as a rigid body about a second center of motion;inserting a distal end of the first cannula through an opening of a patient's body;inserting a distal end of the second cannula through the opening of the patient's body;advancing a first surgical instrument comprising a flexible shaft through the first cannula such that an end effector of the first surgical instrument is beyond the distal end of the first cannula; andadvancing a second surgical instrument comprising a flexible shaft through the second cannula such that an end effector of the second surgical instrument is beyond the distal end of the second cannula;wherein after the advancing of the first and second surgical instruments, the end effectors of the first and second surgical instruments are positioned along first and second legs meeting at an apex of an imaginary triangle, the apex being located distally beyond the end effectors. 17. The method of claim 16, further comprising positioning a surgical port in the opening of the patient's body; wherein inserting the distal ends of the first and second cannulas through the opening of the patient's body comprises inserting the distal ends of the first and second cannulas through the surgical port. 18. The method of claim 16, further comprising positioning the first cannula and the second cannula such that the first center of motion and the second center of motion are proximate to each other and the opening. 19. The method of claim 16, further comprising positioning respective longitudinal axes of the first and second cannulas at the first and second centers of motion across one another. 20. The method of claim 16, further comprising: mounting a proximal end of an endoscope to an endoscope manipulator; andinserting a distal end of the endoscope through the opening in the patient's body such that the distal end of the endoscope is positioned between the first and second cannulas. 21.
