Abstract

Some embodiments provide apparatuses and methods useful to providing control over movement of motorized transport units. In some embodiments, an apparatus providing control over movement of motorized transport units at a shopping facility comprises: a central computer system comprising: a transceiver; a control circuit; 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: obtain, from one or more of the communications received from the motorized transport unit, route condition information comprising information corresponding to an intended route of travel; obtain additional route condition information detected by one or more detectors external to the motorized transport unit; detect an object affecting the intended route of travel; identify an action to be taken by the motorized transport unit with respect to the detected object; and communicate one or more instructions.

First claim

What is claimed is:

1 . An apparatus providing control over movement of motorized transport units at a shopping facility, comprising:
a central computer system that is separate and distinct from a self-propelled motorized transport unit, wherein the central computer system comprises:
a transceiver configured to receive communications from the motorized transport unit located at a shopping facility;
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:
obtain, from one or more of the communications received from the motorized transport unit, route condition information acquired by the motorized transport unit, wherein the route condition information comprises information corresponding to an intended route of travel by the motorized transport unit;
obtain additional route condition information existing at the shopping facility and detected by one or more detectors external to the motorized transport unit;
detect, in response to an evaluation of both the route condition information and the additional route condition information, an object at the shopping facility affecting the intended route of travel;
identify, without user interaction and in response to detecting the object, an action to be taken by the motorized transport unit with respect to the detected object; and
communicate one or more instructions to the motorized transport unit configured to cause the motorized transport unit to implement the action based on the detected object.

2 . The apparatus of claim 1 , wherein the control circuit is further configured to:
identify the object as a customer currently associated with the motorized transport unit; and wherein the control circuit, in identifying the action required, determines one or more route modifications to move the motorized transport unit toward the customer.

3 . The apparatus of claim 1 , wherein the control circuit is further configured to:
determine whether the object is a long term obstruction such that the object is expected to remain at a current location for longer than a threshold period of time; and wherein the control circuit, in identifying the action, identifies one or more route modifications that when implemented cause the motorized transport unit to move around the object when the object is a long term obstruction.

4 . The apparatus of claim 1 , wherein the control circuit is further configured to:
determine whether the object is a short term obstruction such that the object is expected to remain at a current location for less than a threshold period of time; and wherein the control circuit, in identifying the action, identifies one or more route modifications that when implemented cause the motorized transport unit to stop and wait for a period of time and then to proceed along the intended route of travel when the object is a short term obstruction.

5 . The apparatus of claim 1 , wherein the route condition information comprises at least one of bump sensor information, motion sensor information, pull pressure sensor information, and trailing object sensor information.

6 . The apparatus of claim 5 , wherein the additional route condition information comprises video content received from one or more video cameras positioned at the shopping facility and remote from the motorized transport unit.

7 . The apparatus of claim 1 , wherein the control circuit is further configured to:
differentiate the detected object from multiple other potential obstacles; wherein the identified actions is dependent on the differentiation of the object from the multiple other potential obstacles.

8 . A method of providing control over movement of motorized transport units at a shopping facility, comprising:
by a control circuit of an automated central computer system that is separate and distinct from a self-propelled motorized transport unit: obtaining, from one or more communications received from the motorized transport unit, route condition information acquired by the motorized transport unit, wherein the route condition information comprises information corresponding to an intended route of travel by the motorized transport unit; obtaining additional route condition information existing at the shopping facility and detected by one or more detectors external to the motorized transport unit; detecting, in response to an evaluation of both the route condition information and the additional route condition information, an object at the shopping facility affecting the intended route of travel; identifying, without user interaction and in response to detecting the object, an action to be taken by the motorized transport unit with respect to the detected object; and communicating one or more instructions to the motorized transport unit configured to cause the motorized transport unit to implement the action based on the detected object.

9 . The method of claim 8 , wherein the control circuit is further configured to:
identify the object as a customer currently associated with the motorized transport unit; and wherein the identifying the action comprises determine one or more route modifications to move the motorized transport unit toward the customer.

10 . The method of claim 8 , wherein the control circuit is further configured to:
determine whether the object is a long term obstruction such that the object is expected to remain at a current location for longer than a threshold period of time; and wherein the control circuit, in identifying the action, identifies one or more route modifications that when implemented cause the motorized transport unit to move around the object when the object is a long term obstruction.

11 . The method of claim 8 , wherein the control circuit is further configured to:
determine whether the object is a short term obstruction such that the object is expected to remain at a current location for less than a threshold period of time; and wherein the control circuit, in identifying the action, identifies one or more route modifications that when implemented cause the motorized transport unit to stop and wait for a period of time and then to proceed along the intended route of travel when the object is a short term obstruction.

12 . The method of claim 8 , wherein the route condition information comprises at least one of bump sensor information, motion sensor information, pull pressure sensor information, and trailing object sensor information.

13 . The method of claim 12 , wherein the additional route condition information comprises video content received from one or more video cameras positioned at the shopping facility and remote from the motorized transport unit.

14 . The method of claim 8 , wherein the control circuit is further configured to:
detect an obstacle; and differentiate the detected obstacle from multiple other potential obstacles; wherein the identified actions is dependent on the differentiation of the obstacle from the multiple other potential obstacles.
