Abstract

A sensing manipulator of an articulated arm is disclosed. The sensing manipulator includes a compliant section and a movement detection system provided along a first direction of the compliant section such that movement of the compliant section along both the first direction and at least one direction transverse to said first direction, are detectable by the movement detection system.

Claims (39)

1. A programmable motion system for grasping and moving objects, said programmable motion system comprising:

a deformable vacuum end-effector coupled to a distal end of an articulated arm and in communication with a vacuum source;

a movement detection system for providing information regarding movement of the deformable vacuum end-effector with respect to the distal end of the articulated arm in at least two degrees of freedom, and

a controller for determining, responsive to the information regarding movement of the deformable vacuum end-effector with respect to the distal end of the articulated arm whether the deformable vacuum end-effector has made contact with an object to be grasped.

2. The programmable motion system as claimed in claim 1 , wherein the deformable vacuum end-effector is provided as a vacuum cup.

3. The programmable motion system as claimed in claim 2 , wherein the vacuum cup is provided as a tubular or conical bellows.

4. The programmable motion system as claimed in claim 3 , wherein the movement detection system includes a magnetic field sensor.

5. The programmable motion system as claimed in claim 4 , wherein the movement detection system includes an attachment band on a tubular or conical bellows of the vacuum cup.

6. The programmable motion system as claimed in claim 1 , wherein the programmable motion system includes a vacuum sensor that detects air flow.

7. The programmable motion system as claimed in claim 1 , wherein the controller further determines whether to return the object to an input location.

8. The programmable motion system as claimed in claim 1 , wherein the controller further determines whether to increase a vacuum flow provided at the end-effector to maintain the object for transport.

9. The programmable motion system as claimed in claim 1 , wherein the at least two degrees of freedom include any of load, pitch, roll and yaw.

10. The programmable motion system as claimed in claim 1 , wherein the detection system provides information regarding movement of the end-effector with respect to the programmable motion system in three degrees of freedom.

11. A programmable motion system for grasping and moving objects, said programmable motion system comprising:

a deformable vacuum end-effector coupled to a distal end of an articulated arm and in communication with a vacuum source;

a movement detection system for providing information regarding movement of the deformable vacuum end-effector with respect to the distal end of the articulated arm in at least two degrees of freedom, and

a controller for determining, responsive to the information regarding movement of the deformable vacuum end-effector with respect to the distal end of the articulated arm whether a grasp on an object by the deformable vacuum end-effector needs to be adjusted.

12. The programmable motion system as claimed in claim 11 , wherein the deformable vacuum end-effector is provided as a vacuum cup.

13. The programmable motion system as claimed in claim 12 , wherein the vacuum cup is provided as a tubular or conical bellows.

14. The programmable motion system as claimed in claim 13 , wherein the movement detection system includes a magnetic field sensor.

15. The programmable motion system as claimed in claim 14 , wherein the movement detection system includes an attachment band on a tubular or conical bellows of the vacuum cup.

16. The programmable motion system as claimed in claim 11 , wherein the programmable motion system includes a vacuum sensor that detects air flow.

17. The programmable motion system as claimed in claim 11 , wherein the controller further determines whether to return the object to an input location.

18. The programmable motion system as claimed in claim 11 , wherein the controller further determines whether to increase a vacuum flow provided at the end-effector to maintain the object for transport.

19. The programmable motion system as claimed in claim 11 , wherein the at least two degrees of freedom include any of load, pitch, roll and yaw.

20. The programmable motion system as claimed in claim 11 , wherein the detection system provides information regarding movement of the end-effector with respect to the programmable motion system in three degrees of freedom.

21. A programmable motion system for grasping and moving objects, said programmable motion system comprising:

a deformable vacuum end-effector coupled to a distal end of an articulated arm and in communication with a vacuum source;

a movement detection system for providing information regarding movement of the deformable vacuum end-effector with respect to the distal end of the articulated arm in at least two degrees of freedom, and

a controller for determining, responsive to the information regarding movement of the deformable vacuum end-effector with respect to the distal end of the articulated arm whether an object grasped by the deformable vacuum end-effector is oscillating.

22. The programmable motion system as claimed in claim 21 , wherein the deformable vacuum end-effector is provided as a vacuum cup.

23. The programmable motion system as claimed in claim 22 , wherein the vacuum cup is provided as a tubular or conical bellows.

24. The programmable motion system as claimed in claim 23 , wherein the movement detection system includes a magnetic field sensor.

25. The programmable motion system as claimed in claim 24 , wherein the movement detection system includes an attachment band on a tubular or conical bellows of the vacuum cup.

26. The programmable motion system as claimed in claim 21 , wherein the programmable motion system includes a vacuum sensor that detects air flow.

27. The programmable motion system as claimed in claim 21 , wherein the controller further determines whether to return the object to an input location.

28. The programmable motion system as claimed in claim 21 , wherein the controller further determines whether to increase a vacuum flow provided at the end-effector to maintain the object for transport.

29. The programmable motion system as claimed in claim 21 , wherein the at least two degrees of freedom include any of load, pitch, roll and yaw.

30. The programmable motion system as claimed in claim 21 , wherein the detection system provides information regarding movement of the end-effector with respect to the programmable motion system in three degrees of freedom.
