Abstract

A shock absorbing disruptor mounting system for a robotic arm includes a rack comprised of a linear guide structure and a carriage which is configured to travel on the linear guide structure. The carriage is selectively movable between a retracted position and an extended position and includes a plurality of wheels along its length. Each of the wheels has a wheel axis of rotation which is transverse to the direction of the linear guide structure centerline to facilitate rotation of the wheels on at least a portion of the linear guide structure responsive to the travel.

First claim

We claim:

1. A shock absorbing disruptor mount, comprising:
a rack comprised of a linear guide structure which extends in a first direction to define a linear path aligned with a linear guide structure centerline;
a carriage which is configured to travel on said linear guide structure over at least a portion of the linear path;
a shock absorber interposed between a shock absorber rack mounting point disposed on the rack and a shock absorber carriage mounting point disposed on the carriage;
a plurality of wheels which are mounted to the carriage in wheel locations distributed along a length thereof extending in a direction aligned with the linear guide structure centerline;
each of the wheels having a wheel axis of rotation transverse to the direction of the linear guide structure centerline to facilitate rotation of the wheels on at least a portion of the linear guide structure responsive to said travel; and
wherein a position configuration of the plurality of wheels facilitates a yaw rotation of the carriage about a carriage axis of rotation transverse to the linear guide structure centerline responsive to a disruptor force when applied at a location laterally offset from the linear guide structure centerline.

2. The shock absorbing disruptor mount of claim 1 , wherein the position configuration facilitates a selective engagement of the plurality of wheels with the linear guide structure responsive to the yaw rotation while concurrently facilitating travel of the carriage along the linear guide structure responsive to the disruptor force.

3. The shock absorbing disruptor mount of claim 2 , wherein a wheel centerline is defined along the length of the carriage in alignment with the linear guide structure centerline, and the wheel axis of rotation for at least one of said plurality of wheels is laterally offset from the wheel centerline by a predetermined distance.

4. The shock absorbing disruptor mount of claim 3 , wherein the linear guide structure is comprised of first and second rails which extend along the linear path parallel to the linear guide structure centerline, and said plurality of wheels each has a channel formed in an outer periphery thereof for receiving a profiled face of one of said first and second rails.

5. The shock absorbing disruptor mount of claim 4 , wherein at least two wheels of said plurality of wheels are laterally offset from the wheel centerline in a first direction.

6. The shock absorbing disruptor mount of claim 5 , wherein the plurality of wheels are disposed in a staggered configuration between the first and second rails.

7. The shock absorbing disruptor mount of claim 1 , further comprising a motor configured to urge the carriage in a first direction along a length of the linear guide structure.

8. The shock absorbing disruptor mount of claim 7 , wherein said motor includes an actuator which is configured to selectively decouple from an engagement with the carriage responsive to the disruptor force.

9. The shock absorbing disruptor mount of claim 8 , wherein the actuator is comprised of an elongated slider which selectively applies a force to a thrust bearing face of a thrust sleeve disposed on the carriage responsive to the operation of the motor, and wherein the elongated slider extends through an aperture defined in thrust bearing face.

10. The shock absorbing disruptor mount of claim 9 , wherein said aperture facilitates travel of the thrust sleeve along a length of the elongated slider responsive to the disruptor force.

11. The shock absorbing disruptor mount of claim 7 , further comprising a spring element configured to urge the carriage in a second direction opposed from the first direction.

12. A shock absorbing disruptor mount for a robotic arm, comprising:
a base configured to mount on a portion of a robotic arm;
a rack comprised of a linear guide structure and disposed on the base so that the linear guide structure extends along a length of the robotic arm in a first direction toward a robotic grasping device to define a linear path aligned with a linear guide structure centerline;
a carriage which is configured to travel on said linear guide structure over at least a portion of the linear path and selectively movable between a retracted position where said carriage is a first distance from the grasping device and an extended position where said carriage is a second distance from the grasping device, which is less than the first distance;
a shock absorber interposed between a shock absorber rack mounting point disposed on the rack and a shock absorber carriage mounting point disposed on the carriage;
a plurality of wheels which are mounted to the carriage in wheel locations distributed along a length thereof extending in a direction aligned with the linear guide structure centerline;
wherein each of the wheels has a wheel axis of rotation transverse to the direction of the linear guide structure centerline to facilitate rotation of the wheels on at least a portion of the linear guide structure responsive to said travel.

13. The shock absorbing disruptor mount according to claim 12 , wherein a position configuration of the plurality of wheels facilitates a yaw rotation of the carriage about a carriage axis of rotation transverse to the linear guide structure centerline responsive to a disruptor force when applied at a location laterally offset from the linear guide structure centerline.

14. The shock absorbing disruptor mount of claim 13 , wherein the position configuration facilitates a selective engagement of the plurality of wheels with the linear guide structure responsive to the yaw rotation while concurrently facilitating travel of the carriage along the linear guide structure responsive to the disruptor force.

15. The shock absorbing disruptor mount of claim 12 , wherein a wheel centerline is defined along the length of the carriage, and the wheel axis of rotation for at least one of said plurality of wheels is laterally offset from the wheel centerline by a predetermined distance so that the plurality of wheels are in positions which are staggered along the length of the carriage.

16. The shock absorbing disruptor mount of claim 15 , wherein the linear guide structure is comprised of first and second rails which extend along the linear path parallel to the linear guide structure centerline.

17. The shock absorbing disruptor mount of claim 16 , wherein at least two wheels of said plurality of wheels are laterally offset from the wheel centerline in a first direction.

18. The shock absorbing disruptor mount of claim 12 , further comprising a motor configured to selectively urge the carriage in a first direction along a length of the linear guide structure.

19. The shock absorbing disruptor mount of claim 18 , wherein said motor includes an actuator which is configured to selectively decouple from an engagement with the carriage responsive to the disruptor force.

20. The shock absorbing disruptor mount of claim 19 , wherein the actuator is comprised of an elongated slider which selectively applies a force to a thrust bearing face of a thrust sleeve disposed on the carriage responsive to the operation of the motor, and wherein the elongated slider extends through an aperture defined in thrust bearing face.

21. The shock absorbing disruptor mount of claim 20 , wherein said thrust sleeve includes an aperture which facilitates travel of the thrust sleeve along a length of the elongated slider responsive to the disruptor force.
