Abstract

Some embodiments provide systems and methods to assist product stocking on a sales floor of a retail shopping facility. In some implementations, a system comprises a plurality of motorized transport units that are each configured to perform multiple different types of tasks at a retail shopping facility; and a central computer system configured to coordinate the plurality of motorized transport units in performing the multiple different tasks comprising instruct a motorized transport unit to retrieve a specified stocking cart that is carrying a plurality of products that are to be restocked onto product supports that are positioned on the sales floor where customers travel in shopping for products, and further instruct the motorized transport unit to autonomously transport the stocking cart to a specified stocking location on the sales floor corresponding to at least one of the plurality of products carried by the stocking cart.

First claim

What is claimed is:

1. A system to assist product stocking on a sales floor of a retail shopping facility, comprising:
a plurality of motorized transport units that are each configured to perform multiple different tasks at a retail shopping facility; and
a central computer system configured to coordinate the plurality of motorized transport units in performing the multiple different tasks comprising instruct a first motorized transport unit to retrieve a specified first stocking cart that is carrying a first plurality of products that are to be restocked onto product supports that are positioned on the sales floor where customers travel in shopping for products, and further instruct the first motorized transport unit to autonomously transport the first stocking cart to a specified first stocking location on the sales floor corresponding to at least one of the first plurality of products carried by the first stocking cart;
wherein the central computer system is further configured to detect, from sensor data comprising sensor data from the first motorized transport unit, a worker stocking one or more of the products from the first stocking cart, detect from the sensor data that the worker has moved at least a first threshold distance from the first stocking cart, and direct the first motorized transport unit to move the first stocking cart to follow the worker and place the first stocking cart within a second threshold distance of the worker;
wherein each of the plurality of motorized transport units is configured to perform the multiple different tasks at the retail shopping facility comprising at least a first set of tasks to support customers comprising at least the first motorized transport unit being configured to temporarily couple with and transport a movable item container configured to receive items for potential purchase by a customer with which the first motorized transport unit is temporarily associated, a second set of tasks to support workers at the retail shopping facility comprising at least the first motorized transport unit being configured to temporarily couple with and transport the first stocking cart, and a third set of tasks regarding facility maintenance at the retail shopping facility to at least perform a clean-up.

2. The system of claim 1 , wherein the first motorized transport unit detects, through a sensor on the motorized transport unit, a customer on the sales floor within a threshold distance of the first motorized transport unit as the first motorized transport unit transports the first stocking cart through the retail shopping facility, and takes at least a first action to avoid the first motorized transport unit and the first stocking cart from contacting the customer.

3. The system of claim 1 , wherein the central computer system is further configured to receive, from the first motorized transport unit, sensor data indicative of a weight of the first stocking cart and the first plurality of products carried by the first stocking cart, and to confirm based on the sensor data that an expected plurality of products is carried by the first stocking cart.

4. The system of claim 1 , wherein the central computer system is further configured to determine based on the sensor data that the first plurality of products have been unloaded from the first stocking cart, and direct the first motorized transport unit to perform a second task, of the multiple different tasks, at the retail shopping facility and that is unassociated with stocking products and retrieving products.

5. The system of claim 1 , wherein the central computer system is further configured to determine that the first plurality of products have been unloaded from the first stocking cart, instruct the first motorized transport unit to transport the unloaded first stocking cart to a drop location, and instruct the first motorized transport unit to retrieve a specified second stocking cart that is carrying a second plurality of products, and to autonomously transport the second stocking cart to a specified second stocking location on the sales floor.

6. The system of claim 1 , wherein the central computer in directing the first motorized transport unit to follow the worker and place the first stocking cart within the second threshold distance of the worker utilizes the sensor data from the first motorized transport unit and facility sensor data received from sensors external to the first motorized transport unit in determining a distance between the first stocking cart and the worker.

7. The system of claim 1 , wherein the central computer is further configured to implement a work queue application that maintains a task queue for each of the plurality of motorized transport units, tracks the task queues in identifying available motorized transport units to perform different tasks, selects the first motorized transport unit to temporarily cooperate with the first stocking cart to perform the task of transporting the first stocking cart based on a first task queues associated with the first motorized transport unit, and adds the assigned transport task to a first task queue.

8. A system to assist product stocking on a sales floor of a retail shopping facility, comprising:
a plurality of motorized transport units that are each configured to perform multiple different tasks at a retail shopping facility; and
a central computer system configured to coordinate the plurality of motorized transport units in performing the multiple different tasks comprising instruct a first motorized transport unit to retrieve a specified first stocking cart that is carrying a first plurality of products that are to be restocked onto product supports that are positioned on the sales floor where customers travel in shopping for products, and further instruct the first motorized transport unit to autonomously transport the first stocking cart to a specified first stocking location on the sales floor corresponding to at least one of the first plurality of products carried by the first stocking cart;
wherein the central computer system is further configured to identify a mating coupler on the first stocking cart and with which one of the motorized transport units is to couple in transporting the first stocking cart, identify, from the plurality of motorized transport units, that the first motorized transport unit comprises a coupler consistent with the mating coupler on the first stocking cart, and select the first motorized transport unit based on the first motorized transport unit comprising the coupler consistent with the mating coupler on the first stocking cart;
wherein each of the plurality of motorized transport units is configured to perform the multiple different tasks at the retail shopping facility comprising at least a first set of tasks to support customers comprising at least being configured to temporarily couple with and transport a movable item container configured to receive items for potential purchase by a customer with which the first motorized transport unit is temporarily associated, a second set of tasks to support workers at the retail shopping facility comprising at least the first motorized transport unit being configured to temporarily couple with and transport stocking carts, and a third set of tasks regarding facility maintenance at the retail shopping facility to at least perform a clean-up.

9. A system to assist product stocking on a sales floor of a retail shopping facility, comprising:
a plurality of motorized transport units that are each configured to perform multiple different tasks at a retail shopping facility; and
a central computer system configured to coordinate the plurality of motorized transport units in performing the multiple different tasks compri
