3. The robot of claim 2 , wherein the computer-readable storage device stores further instructions which, when executed by the processor, cause the processor to perform operations comprising:
after returning the grasped items back to the container, retrieving second grasped items by repeating the operations of:
moving the manipulator through the open top of the container and grasping one or more other items in the container with the manipulator without any assistance from an individual or other mechanism, to yield the second grasped items;
moving the manipulator and the second grasped items to a position just above the open top of the container and remaining items in the container; and
moving the second grasped items to another area via the manipulator when a number of the second grasped items corresponds to the predetermined number of items.
4. The robot of claim 1 , wherein the robot comprises a mobile robot.
5. The robot of claim 1 , wherein the manipulator comprises at least one of a gripping device, a suction device, and electromagnet, a winch, or a clasp.
6. The robot of claim 1 , wherein the sensor comprises at least one of a global positioning system sensor, a 3D camera, an infrared camera, a stereoscopic camera, an inertial sensor, and odor, metric sensor, a radar, or an electro-acoustic transducer.
7. A system comprising:
a processor;
a robot having a manipulator, the manipulator being separate from a container, the manipulator being used for grasping items in the container;
a sensor configured with the system; and
a computer-readable storage device storing instructions which, when executed by the system, cause the robot to perform operations comprising:
moving the manipulator through an open top of the container and grasping one or more items in the container with the manipulator without any assistance from an individual or other mechanism, to yield grasped items;
moving the manipulator and the grasped items to a position just above the open top of the container; and
moving the grasped items to another area via the manipulator when a number of the grasped items corresponds to a predetermined number of items as detected by the sensor.
8. The system of claim 7 , wherein the computer-readable storage device stores further instructions which, when executed by the system, cause the system to perform operations comprising:
returning the grasped items back to the container when the number of the grasped items does not correspond to the predetermined number of items.
9. The system of claim 8 , wherein the computer-readable storage device stores further instructions which, when executed by the system, cause the system to perform operations comprising:
after returning the grasped items back to the container, retrieving second grasped items by repeating the operations of:
moving the manipulator through the open top of the container and grasping one or more other items in the container with the manipulator without any assistance from an individual or other mechanism, to yield the second grasped items;
moving the manipulator and the second grasped items to a position just above the open top of the container and remaining items in the container; and
moving the second grasped items to another area via the manipulator when a number of the second grasped items corresponds to the predetermined number of items.
10. The system of claim 7 , wherein the robot comprises a mobile robot.
11. The system of claim 7 , wherein the manipulator comprises at least one of a gripping device, a suction device, and electromagnet, a winch, or a clasp.
12. The system of claim 7 , wherein the sensor comprises at least one of a global positioning system sensor, a 3D camera, an infrared camera, a stereoscopic camera, an inertial sensor, and odor, metric sensor, a radar, or an electro-acoustic transducer.
13. The system as defined in claim 7 , wherein the computer-readable storage device stores further instructions which, when executed by the system, cause the system to perform operations comprising:
returning the grasped items back to the container when the number of grasped items does not correspond to the predetermined number of items.
14. The system as defined in claim 13 , wherein the computer-readable storage device stores further instructions which, when executed by the system, cause the system to perform operations comprising:
after returning the grasped items back to the container, retrieving second grasped items by repeating the operations of:
moving the manipulator through the open top of the container and grasping one or more other items in the container with the manipulator without any assistance from an individual or other mechanism, to yield the second grasped items;
moving the manipulator and the second grasped items to a position just above the open top of the container and remaining items in the container; and
moving the second grasped items to another area via the manipulator when a number of the second grasped items corresponds to the predetermined number of items.
15. A method comprising:
moving a manipulator through an open top of a container and grasping one or more items in the container with the manipulator without any assistance from an individual or other mechanism, to yield grasped items;
moving the manipulator and the grasped items to a position just above the open top of the container; and
moving the grasped items to another area when a number of the grasped items corresponds to a predetermined number of items.
16. The method as defined in claim 15 , further comprising:
returning the grasped items back to the container when the number of items grasped by the manipulator does not correspond to the predetermined number of items.
