Abstract

Claims (29)

1. A method of positioning, comprising:

providing a structure, at least one base, and a plurality of actuators configured to support the structure over the at least one base and to move the structure relative to the at least one base in response to extension or retraction of one or more actuators; and

throughout movement of the structure, three or more of the actuators maintaining contact with the structure through a joint having at least four degrees of freedom (DOF).

2. The method of claim 1 , further comprising at least two actuators maintaining contact with the structure through a joint having five DOF.

3. The method of claim 2 , further comprising at least two actuators maintaining contact with the structure through a joint having four DOF.

4. The method of claim 1 , further comprising at least two actuators maintaining contact with the structure through a joint having four DOF.

5. The method of claim 1 , wherein at least one joint having four DOF is a magnetic joint.

6. The method of claim 1 , wherein at least one joint having five DOF is a magnetic joint.

7. The method of claim 1 , wherein each of the three or more actuators has a magnetic joint with the structure.

8. The method of claim 1 , wherein an actuator having a 4 DOF joint with the structure has a cylindrical end that contacts the structure.

9. The method of claim 1 , wherein an actuator having a 5 DOF joint with the structure has a hemispherical end that contacts the structure.

10. The method of claim 1 , wherein the structure includes a lengthwise groove, depression, or channel.

11. The method of claim 10 , wherein the lengthwise groove, depression, or channel is configured to hold at least one optical fiber.

12. The method of claim 10 , wherein the structure includes a V-groove configured to hold at least one optical fiber.

13. The method of claim 1 , wherein:

the structure comprises a top plate and the at least one base includes at least one base plate, and

the three or more actuators that support the top plate are coupled to the at least one base plate.

14. The method of claim 13 , wherein the top plate includes angled sides engaged by the three or more actuators and the at least one base plate includes angle side pieces to which the three or more actuators are coupled and the angled sides of the top plate and the angled side pieces of the at least one base plate have the same angle with respect to a vertical plane or axis.

15. The method of claim 1 , wherein the structure includes an end plate.

16. The method of claim 15 , wherein the coupling is a magnetic coupling.

17. A method of making a positioner, comprising;

providing a structure and at least one base;

arranging a plurality of actuators to support the structure over the at least one base and to move the structure relative to the at least one base in response to extension or retraction of one or more actuators; and

arranging three or more of the actuators to maintain contact with the structure through a joint having at least four degrees of freedom (DOF).

18. The method of claim 17 , further comprising:

providing the three or more actuators to include at least two actuators that maintain contact with the top plate through a joint having four DOF; and

providing at least one actuator that maintains contact with the top plate though a joint having five DOF.

19. The method of claim 17 , wherein the top plate includes angled sides engaged by the three or more actuators and the base plate includes angle side pieces to which the three or more actuators are coupled and the angled sides of the top plate and the angled side pieces of the base plate have the same angle with respect to a vertical plane or axis.

20. The method of claim 17 , wherein the structure includes an end plate and the method includes providing at least one actuator that engages the endplate.
