Abstract

A system can function relative to an item, a tether, and a robotic manipulator. The tether can correspond to a loop or other structure that can be mountable or mounted in an installed state in which the tether is secured with the item to facilitate lifting the item by lifting of the tether. The robotic manipulator can include a robotic end effector engageable with the tether in the installed state. The robotic end effector can be configurable to an engaged state in which the tether is coupled with the robotic end effector. The robotic manipulator in the engaged state can be operable to move the item by lifting of the tether in the installed state.

First claim

What is claimed is:

1. A method of enabling robotic package handling, the method comprising:
accessing a shipping package;
applying an adhesive tape along a first portion of a pair of flaps of the shipping package to secure the first portion of the pair of flaps together;
establishing a tether in an installed state by adding the tether to the shipping package so as to extend from the shipping package, the tether comprising a loop extending from the exterior of the shipping package, wherein establishing the tether comprises forming the tether from the adhesive tape such that the tether features a twisted form factor in the course of applying the adhesive tape to close the flaps;
applying the adhesive tape along a second portion of the pair of flaps to secure the second portion of the pair of flaps together;
accessing a robotic manipulator or end effector comprising:
an actuator body having an operative side;
a c-shaped discontinuous ring coupled with the actuator body, wherein the ring comprises a ring body extending in a curved shape between a first end and a second end, wherein the first end and second end are spaced apart from one another to define a gap, and wherein the gap is arranged as a passage between an interior area bounded by the ring body and an exterior area outside of the ring body; and
a drive arranged and configured to rotate the ring between at least an open state and a closed state, wherein in the open state the ring is arranged so that the gap is arranged along and accessible from the operative side of the actuator body, and wherein in the closed state the ring is arranged so that the gap is inaccessible from the operative side and so that the ring body extends continuously to close off a space along the operative side;

moving the robotic manipulator, with the ring in the open state, in a path that causes the gap to cross over and receive the loop of the tether therethrough so that at least a portion of the loop of the tether is arranged within the interior area bounded by the ring body;
engaging the tether with the robotic manipulator by rotating the ring with the drive to the closed state, wherein engaging the tether with the robotic manipulator causes the robotic manipulator to be in an engaged state in which the loop of the tether is captured within the interior area bounded by the ring body; and
lifting or conveying the package by moving the robotic manipulator with the robotic manipulator in the engaged state.

2. The method of claim 1 , wherein the moving the robotic manipulator, the engaging the tether, and the lifting or conveying are performed relative to a cargo bay of a robotic delivery vehicle.

3. The method of claim 1 , wherein the shipping package comprises a shipping box or a shipping envelope.

4. A method comprising:
accessing an item;
establishing a tether in an installed state so as to extend from the item and facilitate robotic engagement with the tether, wherein establishing the tether comprises forming the tether from adhesive tape such that the tether features a twisted form factor in the course of applying the adhesive tape to close the item;
engaging the tether with a robotic manipulator, wherein engaging the tether with the robotic manipulator causes the robotic manipulator to be in an engaged state in which the tether is coupled with the robotic manipulator; and
lifting or conveying the item by moving the robotic manipulator with the robotic manipulator in the engaged state.

5. The method of claim 4 , wherein establishing the tether comprises using means for adding the tether to the item.

6. The method of claim 4 , wherein establishing the tether comprises securing the tether to an exterior of the item.

7. The method of claim 4 , further comprising marking indicia on the tether or on structure associated with the tether so as to facilitate robotic location of the tether through visual recognition of the indicia.

8. The method of claim 4 , wherein the engaging the tether with the robotic manipulator comprises engaging with a robotic manipulator comprising:
an actuator body having an operative side;
a discontinuous ring coupled with the actuator body, wherein the ring comprises a ring body extending in a curved shape between a first end and a second end, wherein the first end and second end are spaced apart from one another to define a gap, and wherein the gap is arranged as a passage between an interior area bounded by the ring body and an exterior area outside of the ring body; and
a drive arranged and configured to rotate the ring between at least an open state and a closed state, wherein in the open state the ring is arranged so that the gap is arranged along and accessible from the operative side of the actuator body, and wherein in the closed state the ring is arranged so that the gap is inaccessible from the operative side and so that the ring body extends continuously to close off a space along the operative side.

9. An inventory management system comprising:
an item;
adhesive tape arranged closing the item and further forming a tether mounted in an installed state in which the tether is secured with the item to facilitate lifting the item by lifting of the tether, wherein the tether is formed from the adhesive tape such that the tether features a twisted form factor; and
a robotic manipulator comprising a robotic end effector engageable with the tether in the installed state, wherein the robotic end effector is configurable to an engaged state in which the tether is coupled with the robotic end effector, and wherein the robotic manipulator in the engaged state is operable to move the item by lifting of the tether in the installed state.

10. The inventory management system of claim 9 , wherein the tether comprises a loop.

11. The inventory management system of claim 9 , further comprising a coupler machine configured to mount the tether into the installed state.

12. The inventory management system of claim 9 , further comprising a decoupler machine configured to at least one of unmount the tether or remove the tether from the installed state.

13. The inventory management system of claim 9 , further comprising at least one sensor configured to provide information indicative of a center of gravity of the item to facilitate placement of the tether relative to the center of gravity.

14. The inventory management system of claim 9 , wherein the tether is a first tether, wherein the system further comprises a second tether, and wherein the first tether and the second tether are secured with the item on differing sides of a center of gravity of the item.
