Abstract

Claims (24)

1 . An object gripping mechanism for use with a robotic arm, the object gripping mechanism comprising:

a plurality of retractable arms connected to an attachment modular, wherein each retractable arm of the plurality of retractable arms is pivotably connected with the attachment modular, wherein each of the plurality of retractable arms comprises an object engagement feature configured to selectably engage an object, wherein the object engagement feature comprises a plunger and a plunger connector, wherein the plunger connector is operably coupled to the retractable arm, such that the plunger remains at least substantially parallel to a surface of the object during operation; and

a drive mechanism positioned within each of the plurality of retractable arms and configured to pivot the object engagement feature relative to a corresponding retractable arm, wherein the drive mechanism comprises a timing belt connected to at least the plunger connector, wherein the timing belt causes the plunger connector to rotate relative to a movement of the retractable arm such that an orientation of the plunger remains static relative to the object.

2 . The object gripping mechanism of claim 1 , further comprises one or more movement mechanisms collectively configured to pivot the plurality of retractable arms to a desired position.

3 . The object gripping mechanism of claim 2 , wherein the drive mechanism comprises a gear operably engaged with one of the one or more movement mechanisms, wherein the timing belt is operably connected with the gear and extending to the object engagement feature, wherein the timing belt is configured to pivot the object engagement feature relative to the corresponding retractable arm based on movement of the one of the one or more movement mechanisms.

4 . The object gripping mechanism of claim 3 , wherein each of the plurality of retractable arms further comprise an arm actuating gear configured to engage an arm gear, wherein the arm gear is rotatably coupled with a timing belt gear at a first end of the timing belt, wherein the object engagement feature is attached at a second end of the timing belt.

5 . The object gripping mechanism of claim 2 , wherein at least one of the one or more movement mechanisms comprise a motor.

6 . The object gripping mechanism of claim 2 , wherein the plurality of retractable arms comprises at least four retractable arms.

7 . The object gripping mechanism of claim 6 , wherein the one or more movement mechanisms is embodied as a single movement mechanism configured for synchronously moving all of the at least four retractable arms.

8 . The object gripping mechanism of claim 1 , wherein the plunger is rigidly attached to the plunger connector.

9 . The object gripping mechanism of claim 1 , wherein each of the plurality of retractable arms are controlled via a separate movement mechanism.

10 . The object gripping mechanism of claim 1 , wherein the plurality of retractable arms define a plurality of gears configured to independently adjust the retractable arm and the object engagement feature disposed on said retractable arm.

11 . The object gripping mechanism of claim 1 , wherein the plurality of retractable arms extend between a pivot end and a distal end, and the object engagement feature is pivotable about the distal end.

12 . The object gripping mechanism of claim 1 , wherein the object engagement feature is a vacuum gripper.

13 . The object gripping mechanism of claim 1 , wherein the plurality of retractable arms is movable between a retracted position and an extended position.

14 . A robotic arm comprising:

a plurality of retractable arms connected to an attachment modular, wherein each retractable arm of the plurality of retractable arms is pivotably connected with the attachment modular, wherein each of the plurality of retractable arms comprises an object engagement feature configured to selectably engage an object, wherein the object engagement feature comprises a plunger and a plunger connector, wherein the plunger connector is operably coupled to the retractable arm, such that the plunger remains at least substantially parallel to a surface of the object during operation; and

a drive mechanism positioned within each of the plurality of retractable arms and configured to pivot the object engagement feature relative to a corresponding retractable arm, wherein the drive mechanism comprises a timing belt connected to at least the plunger connector, wherein the timing belt causes the plunger connector to rotate relative to a movement of the retractable arm such that an orientation of the plunger remains static relative to the object.

15 . The robotic arm of claim 14 , wherein the attachment modular is attached to the robotic arm via one or more fasteners.

16 . The robotic arm of claim 14 , wherein the plurality of retractable arms are configured to extend between a pivot end and a distal end, and the object engagement feature is pivotable about the distal end.

17 . The robotic arm of claim 14 , wherein the plurality of retractable arms define a plurality of gears configured to independently adjust the retractable arm and the object engagement feature disposed on said retractable arm.

18 . The robotic arm of claim 14 , wherein the plurality of retractable arms is movable between a retracted position and an extended position.

19 . The robotic arm of claim 14 , wherein the plunger is rigidly attached to the plunger connector.

20 . The robotic arm of claim 14 , wherein the object engagement feature is a vacuum gripper.
