Abstract

Some embodiments include a track system comprising: an elevated track system comprising a series of elevated tracks that are positioned elevated above a sales floor and products distributed over at least a portion of the sales floor of a shopping facility, and configured such that multiple motorized transport units travel along the series of elevated tracks in traversing at least portions of the shopping facility.

First claim

What is claimed is:

1. A track system, comprising:
an elevated track system comprising a series of elevated tracks that are positioned elevated above a sales floor and products, distributed over at least a portion of the sales floor of a shopping facility, and configured such that multiple motorized transport units travel along the series of elevated tracks in traversing at least portions of the shopping facility, wherein at least some of the elevated tracks are positioned above a drop down ceiling;
one or more chutes each cooperated with one of the elevated tracks and configured to provide a passage for one or more of the motorized transport units between the series of elevated tracks and the sales floor, wherein each of the one or more chutes have dimensions such that the motorized transport units are configured to be position within the chute while being transported through the chute; and
a safety catch cooperated under at least a first elevated track of the at least some of the elevated tracks and that extends over an area of the sales floor where people walk, wherein the safety catch is configured to catch objects that unintentionally fall from the first elevated track.

2. The system of claim 1 wherein at least one of the one or more chutes comprise vertical chutes with at least two channels formed therein to receive a corresponding part of each motorized transport unit that passes through the at least one chute.

3. The system of claim 1 , wherein at least a first elevated track is configured to allow a first motorized transport unit traveling on the first elevated track to pass a second motorized transport unit traveling on the first elevated track.

4. The system of claim 1 , wherein the elevated track system further comprises one or more staging areas extending from a first track of the series of elevated tracks and configured to receive one or more motorized transport units that are idle and awaiting instructions from the central computer system and allowing the one or more motorized transport units to be maintained in the elevated track system without interfering with one or more other motorized transport units as they travel along at least the first track of the series of elevated tracks.

5. The system of claim 4 , wherein at least one of the one or more elevated staging areas comprises one or more charging stations each configured to electrically couple with any one of the multiple motorized transport units and charge a rechargeable battery of the coupled motorized transport unit.

6. The system of claim 1 , further comprising:
a central computer system of the shopping facility configured to communicate routing instructions to the multiple motorized transport units directing the one or more motorized transport units along one or more tracks of the series of elevated tracks in moving to respective desired destinations within the shopping facility.

7. The system of claim 6 , wherein the central computer system further comprises:
a control circuit coupled with the transceiver; and
a memory coupled to the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to perform the steps of:
track locations of each of the multiple motorized transport units; and
cooperatively coordinate the movements of the multiple motorized transport units as they travel along the series of elevated tracks and the sales floor.

8. The system of claim 7 , wherein the control circuit in executing the computer instructions is further configured to:
identify a location where a motorized transport unit is desired to perform a task;
identify a first motorized transport unit, of the multiple motorized transport units, intended to be directed to the identified location to perform the task;
determine first routing instructions that include directions along one or more elevated tracks of the series of elevated tracks that the first motorized transport unit is to follow in moving to the identified location; and
communicate the first routing instructions to the first motorized transport unit.

9. The system of claim 1 , wherein each of the at least some of the elevated tracks is positioned extending over portions of the sales floor including elevated above and extending over multiple different product support shelving units and areas where people walk.

10. The system of claim 1 , wherein each of the elevated tracks of the series of elevated tracks intersects at least one other of the multiple elevated tracks extending away in a different direction and defining multiple intersections between the at least two intersecting elevated tracks, and wherein the multiple motorized transport units are configured to transition at one or more of the intersections between different elevated tracks of the series of elevated tracks in traversing at least a portion of the sales floor of the shopping facility.

11. A method of routing motorized transport units through a shopping facility, comprising:
by a central computer system of a shopping facility:
instructing multiple motorized transport units to access an elevated track system comprising a series of elevated tracks that are positioned elevated above a sales floor and products, and distributed over at least a portion of the sales floor of a shopping facility, wherein at least some of the elevated tracks are positioned above a drop down ceiling, and a safety catch cooperated under at least a first elevated track of the at least some of the elevated tracks and that extends over an area of the sales floor where people walk, wherein the safety catch is configured to catch objects that unintentionally fall from the first elevated track;
instructing the multiple motorized transport units to access at least one of one or more chutes each cooperated with one of the elevated tracks, wherein each of the one or more chutes provides a passage for one or more of the motorized transport units between the series of elevated tracks and the sales floor and wherein each of the one or more chutes have dimensions such that the motorized transport units are configured to be position within the chute while being transported through the chute; and
instructing the multiple motorized transport units to travel along the series of elevated tracks in traversing at least portions of the shopping facility.

12. The method of claim 11 , wherein at least one of the one or more chutes comprise vertical chutes with at least two channels formed therein to receive a corresponding part of each motorized transport unit that passes through the at least one chute.

13. The method of claim 11 , wherein the instructing the multiple motorized transport units to travel along the series of elevated tracks comprises instructing at least first and second motorized transport units to travel along at least a first elevated track having a width such that the first motorized transport unit traveling on the first elevated track passes the second motorized transport unit traveling on the first elevated track.

14. The method of claim 11 , further comprising:
instructing one or more of the multiple motorized transport units to enter one or more staging areas of the elevated track system that extends from a first track of the series of elevated tracks, wherein the one or more staging areas are configured to receive one or more motorized transport units that are idle and awaiting instructions from the central computer system and allow the one or more motorized transport units to be maintained in the elevated track system without interfering with one or more other motorized transport units as they travel along at least
