6. The system as claimed in claim 4 , wherein the load detection system monitors load balance.

7. An object acquisition system comprising a high flow vacuum source including a blower that provides a high flow vacuum through an opening having a center at a distal end of an end effector of a programmable motion device, wherein the end effector includes a cover having a compliant distally facing foam material, the opening passing through the foam material such that an object is engageable at the opening without passing through the opening while permitting substantial flow of air through the opening that assists in maintaining the object against the opening for movement by the end effector, wherein the opening is provided as a single contiguous opening of the end effector that includes radially extending open areas that extend radially from the center of the opening toward a periphery of the opening.

8. The object acquisition system as claimed in claim 7 , wherein vacuum pressure is no more than about 50,000 Pascals below atmospheric.

9. The object acquisition system as claimed in claim 7 , wherein a maximum air flow rate is at least about 100 cubic feet per minute.

14. The method as claimed in claim 11 , wherein the method further includes the step of determining whether to maintain a grasp on an object responsive to a characterization of the load.

15. The method as claimed in claim 14 , wherein characterization of the load involves determining a relative weight of the object.

16. The method as claimed in claim 14 , wherein characterization of the load involves determining a relative balance of the load provided by the object.

17. The method as claimed in claim 11 , wherein the method further includes the step of characterizing the load presented by the object.

18. A method of engaging and moving a load presented by an object at an end effector of an articulated arm in a high flow vacuum system, said method comprising the steps of:

providing a high flow vacuum using a blower, said high flow vacuum being provided at all of plural openings at a contact surface of the end effector, the end effector including a flexible bellows and including a central region of the contact surface;

engaging the object at the contact surface while permitting substantial flow of air through all of the openings, the substantial flow of air being greater at the central region of the contact surface than at regions more radian peripheral to the central region of the contact surface;

lifting the engaged object using the end effector while permitting substantial flow of air through all of the openings and while permitting flexing of the bellows in any of three mutually orthogonal directions; and

moving the engaged object using the end effector and the articulated arm.
