Abstract

Systems and methods for a vehicle mounted articulator are described. A vehicle conveniently allows an articulator to be moved to various remote work sites. In one embodiment, the articulator can be mounted on a movable base, thereby increasing the flexibility of use and/or reach of the articulator. Such vehicle-mounted articulators can be subjected to various potentially damaging situations due to motion of the vehicle. Various features that allow safe operation of the vehicle and the articulator are disclosed.

Claims

1. A vehicle, comprising:

a movement mechanism configured to facilitate movement of said vehicle;

a body coupled to said movement mechanism;

an articulator coupled to said body so as to allow operation of said articulator from said vehicle;

a coordinate measuring machine coupled to an end of the articulator; and

a plurality of retractable stabilizers, configured to provide a sufficiently rigid and stable coupling with a surface;

wherein said articulator is coupled to said body via a platform, said articulator being mounted to said platform and said platform being coupled to said body and

wherein the vehicle further comprises a platform movement mechanism configured to allow movement of said platform with respect to said body to increase the range of motion of said articulator during its operation.

2. The vehicle of claim 1, further comprising a substantially self-contained drive system that allows a human operator to drive said vehicle to different locations.

3. The vehicle of claim 2, wherein said drive system comprises an electrical motor that is powered by one or more on-board batteries.

4. The vehicle of claim 3, wherein said one or more on-board batteries also power operation of said articulator.

5. The vehicle of claim 2, wherein said vehicle includes a plurality of wheels to facilitate said movement, at least one of said plurality of wheels being steerable by said operator.

6. The vehicle of claim 1, wherein the stabilizers form a metal-to-metal coupling with the surface when extended.

7. The vehicle of claim 1, wherein said platform is movable in a rotational manner with respect to said body.

8. The vehicle of claim 1, wherein said platform is movable in a translational manner.

9. The vehicle of claim 8, wherein said platform movement mechanism comprises a mounting plate coupled to one or more rails that provide guidance for a substantially linear motion of said mounting plate relative to said body, said mounting plate configured to allow mounting of said articulator thereon.

10. The vehicle of claim 8, wherein said translational motion comprises a motion of said platform along a longitudinal direction defined by front and rear of said vehicle.

11. The vehicle of claim 8, wherein said translational motion comprises a motion of said platform along a direction having a vertical component.

12. The vehicle of claim 1, wherein said articulator includes a distal end for mounting of an end assembly.

13. The vehicle of claim 12, wherein said body defines an opening that receives at least a portion of said end assembly to provide protection for said end assembly.

14. The vehicle of claim 13, wherein said opening is dimensioned so as to allow substantially all of said end assembly to be within a volume defined by said body.

15. The vehicle of claim 13, further comprising a latching mechanism that secures said distal end or said end assembly to said body when said articulator is not in use or when said vehicle is in motion.

16. The vehicle of claim 1, further comprising an interlock system that inhibits or restricts operation of said articulator under one or more selected conditions.

17. The vehicle of claim 16, wherein said interlock system disables movement of said vehicle when said articulator is in its deployed configuration.

18. The vehicle of claim 16, wherein said interlock system allows only a limited movement of said articulator transitions between its deployed configuration and secured configuration.

19. The vehicle of claim 18, wherein said limited movement comprises limited speed and direction of said movement to reduce the likelihood of damage to said articulator during transition between said deployed and secured configurations.

20. The vehicle of claim 16, further comprising an override mechanism that allows overriding of at least one of inhibiting or restricting functionality of said interlock system.

21. The vehicle of claim 1, wherein said articulator comprises a plurality of arm sections, with movement of each arm section being effectuated by drive cables driven by motors that are positioned proximately to the location where said articulator is mounted to said body, thereby reducing the moment of inertia of said articulator about said mounting location.

22. A method for operating articulators, comprising:

providing a movement mechanism to a vehicle so as to facilitate movement of said vehicle;

mounting an articulator on said vehicle such that said articulator can be operated at different locations reachable by movements of said vehicle;

mounting a coordinate measuring machine on said articulator such that the machine can precisely measure position at a variety of coordinates; and

mounting a plurality of retractable stabilizers to the vehicle configured to provide a sufficiently rigid and stable coupling with a surface;

wherein said mounting of said articulator to said vehicle comprises mounting said articulator to a platform that is movable relative to said vehicle and wherein said platform is movable in a translational manner.

23. The method of claim 22, wherein said movement mechanism comprises a substantially self-contained drive system that allows a human operator to drive said vehicle to different locations.

24. The method of claim 22, wherein the stabilizers form a metal-to-metal coupling with the surface when extended.

25. The method of claim 22, wherein said mounting of said articulator to said vehicle comprises mounting said articulator to a platform that is movable relative to said vehicle.

26. The method of claim 25, wherein said platform is movable in a translational manner.

27. The method of claim 26, wherein said translational motion comprises a motion of said platform along a direction having a vertical component.

28. The method of claim 25, wherein said platform is movable in a rotational manner with respect to said body.

29. The method of claim 26, wherein said translational motion comprises a motion of said platform along a longitudinal direction defined by front and rear of said vehicle.

30. The method of claim 22, further comprising providing a securing assembly that secures said articulator at or near its distal end to reduce likelihood of damage to said articulator during motion of said vehicle.

31. The method of claim 22, further comprising providing an interlock system that inhibits or restricts operation of said articulator under one or more selected conditions.

32. The method of claim 31, wherein said interlock system disables movement of said vehicle when said articulator is in its deployed configuration.

33. The method of claim 31, wherein said interlock system allows only a limited movement of said articulator transitions between its deployed configuration and secured configuration.

34. The method of claim 33, wherein said limited movement comprises limited speed and direction of said movement to reduce the likelihood of damage to said articulator during transition between said deployed and secured configurations.

35. The method of claim 31, further comprising providing an override mechanism that allows overriding of at least one of inhibiting or restricting functionality of said interlock system.
