Abstract

In accordance with an embodiment, the invention provides an end effector for use with a programmable motion device. The end effector includes a pair of mutually opposing surfaces, at least one of the pair of mutually opposing surfaces being movable with respect to an end effector support structure for supporting the at least one of the pair of mutually opposing surfaces.

First claim

What is claimed is:

1 . A programmable motion device, comprising:
a plurality of articulated arm sections coupled to an end-effector, and said end-effector including a pair of grippers that are coupled to an actuator for moving the pair of grippers towards and away from each other, said pair of grippers being movable toward each other for grasping an object therebetween by movement of the actuator in a linear upward direction that is substantially orthogonal to a direction extending between the pair of grippers.

2 . The programmable motion device as claimed in claim 1 , wherein the pair of grippers include a pair of rollers.

3 . The programmable motion device as claimed in claim 1 , wherein the pair of grippers include a pair of spheres.

4 . The programmable motion device as claimed in claim 1 , wherein the pair of grippers each includes a mutually opposing curved surface of a non-round gripper element.

5 . The programmable motion device as claimed in claim 1 , wherein the actuator includes a pair of four-bar linkage structures.

6 . The programmable motion device as claimed in claim 1 , wherein the actuator includes a pair of rack and pinion gear systems.

7 . The programmable motion device as claimed in claim 6 , wherein each rack and pinon gear system includes a tensioning mechanism.

8 . A programmable motion device, comprising:
a plurality of articulated arm sections coupled to an end-effector, and said end-effector including a pair of grippers being coupled to a pair of four-bar linkage structures for grasping an object, the pair of grippers being movable toward each other for grasping an object therebetween by movement of the pair of four-bar linkage structures in a linear upward direction that is substantially orthogonal to a direction extending between the pair of grippers.

9 . A programmable motion device, comprising:
a plurality of articulated arm sections coupled to an end-effector, and said end-effector including a pair of grippers that are coupled to a pair of tensioning elements for moving the pair of grippers towards and away from each other, said pair of grippers being movable toward each other for grasping an object therebetween by movement of the pair of tensioning elements in a linear upward direction that is substantially orthogonal to a direction extending between the pair of grippers, each tensioning element drawing a respective gripper along a rack and pinion system.

10 . The programmable motion device as claimed in claim 9 , wherein the pair of grippers includes a pair of rollers, wherein each roller includes a pinion gear that engages a rack section of the rack and pinion system.

11 . The programmable motion device as claimed in claim 10 , wherein each tensioning element is drawn around a rotor actuator for moving each roller in a direction that is generally orthogonal to a direction between the pair of grippers.

12 . The programmable motion device as claimed in claim 11 , wherein each tensioning element acts against a biasing spring.

13 . The programmable motion device as claimed in claim 12 , wherein the biasing spring urges the rack section against the pinion gear of one of the rollers.
