Modular and configurable pick/put wall

1. An order fulfillment system, comprising:

a receiving apparatus comprising a front frame having a pair of vertical supports that receives one or more horizontal bars having an array of node locations located proximate to one or more openings;

a mobile apparatus, wherein the mobile apparatus having at least one receptacle is positionable behind the front frame of the receiving apparatus so as to align an opening of the receptacle for holding articles with one of the array of node locations such that the receptacle located behind the front frame is accessible for article retrieval by passing through the one or more openings of the front frame of the receiving apparatus; and

a light order fulfillment system comprising more than one article indicating module, wherein each module is mounted to a respective node location on the one or more horizontal bars of the receiving apparatus and configured to selectively illuminate the receptacles of the mobile apparatus docked behind the receiving apparatus.

2. The order fulfillment system of claim 1 , further comprising a pick-to-light controller that is in communication with a warehouse management system to interact with an operator to effect one of a pick from or put to a selected receptacle.

3. The order fulfillment system of claim 2 , further comprising:

an identification reader to read an identification artifact carried by the mobile apparatus; and

a controller in communication with the identification reader to read an identifier of the configuration of receptacles and to configure operation of the light order system to the configuration of receptacles.

4. The order fulfillment system of claim 1 , wherein the mobile apparatus comprises a mobile container with horizontally accessible receptacles formed by horizontal and vertical dividers.

5. The order fulfillment system of claim 1 , wherein one or more of the horizontal bars are vertically adjustable on the vertical supports to align with one of a top and a bottom of a selected receptacle of a selected mobile apparatus.

6. The order fulfillment system of claim 5 , further comprising:

an identification reader configured to read an identification artifact carried by the mobile apparatus; and

a controller in communication with the identification reader configured to read an identifier of the configuration of receptacles and to configure operation of the light order system by positioning the array of node locations to correspond to the configuration of receptacles.

7. The order fulfillment system of claim 6 , wherein one or more of the node locations are horizontally adjustable.

8. The order fulfillment system of claim 6 , wherein one or more of the node locations are automatically adjustable.

9. The order fulfillment system of claim 6 , wherein a selected node location is electrically selectable from a range of node locations that include at least one unselected node location that does not correspond to any receptacle.

10. The order fulfillment system of claim 1 , wherein each of the article indicating modules includes receptacle illuminating light.

11. The order fulfillment system of claim 1 , wherein receiving apparatus is mounted to a floor and comprises a stopping structure configured to laterally constrain a received mobile apparatus.

12. The order fulfillment system of claim 1 , further comprising:

an autonomous robot to move a selected mobile apparatus; and

a mobility control system to direct the autonomous robots to move the mobile apparatus.

13. An order fulfillment system, comprising:

a receiving apparatus comprising a front frame having a pair of vertical supports that receives one or more horizontal bars defining one or more openings;

an array of node locations located on the one or more horizontal bars proximate to the one or more openings; and

a light order fulfillment system comprising more than one article indicating module, wherein each module is mounted to a respective node location on the one or more horizontal bars of the receiving apparatus,

wherein the receiving apparatus is configured to receive a mobile apparatus positionable behind the front frame so as to align an opening of a receptacle for holding articles with one of the array of node locations such that the receptacle located behind the front frame is accessible for article retrieval by passing through the one or more openings of the front frame of the receiving apparatus,

wherein the light order fulfillment system is configured to selectively illuminate the receptacles of the mobile apparatus docked behind the receiving apparatus.

14. The order fulfillment system of claim 13 , further comprising a pick-to-light controller in communication with a warehouse management system and configured to interact with an operator to effect one of a pick from or put to a selected receptacle.

15. The order fulfillment system of claim 14 , further comprising:

an identification reader configured to, in an instance in which the receiving apparatus receives more than one mobile apparatus, read an identification artifact carried by each of the more than one mobile apparatus; and

a controller in communication with the identification reader configured to read an identifier of the configuration of receptacles and to configure operation of the light order system to the configuration of receptacles.

16. The order fulfillment system of claim 13 , wherein one or more of the horizontal bars are vertically adjustable on the vertical supports to align with one of a top and a bottom of a selected receptacle of the mobile apparatus.

17. The order fulfillment system of claim 13 , wherein one or more of the node locations are horizontally adjustable.

18. The order fulfillment system of claim 13 , wherein one or more of the node locations are automatically adjustable.

19. The order fulfillment system of claim 13 , wherein the receiving apparatus is mounted to a floor and comprises a stopping structure configured to laterally constrain the mobile apparatus received by the receiving apparatus.
