Systems, devices and methods of controlling motorized transport units in a retail shopping facility

A system to fulfill a customer order, comprising:

• a plurality of self-propelled motorized transport units (MTU) each configured to move through at least a portion of a retail shopping facility that is configured such that customers regularly enter and travel through at least a sales floor portion of the retail shopping facility to locate and purchase products from the retail shopping facility, wherein each of the motorized transport units comprises:
• an item container configured to receive products placed into the item container by a customer and retain the products intended to be purchased;
• an MTU control circuit;
• a product scanner communicatively coupled with the MTU control circuit and configured scan and obtain product identifying information for products placed into the item container and communicate the product identifying information to the MTU control circuit;
• a user interface communicatively coupled with the MTU control circuit wherein the MTU control circuit is configured to present information to the customer, including an identifier of the products placed into the item container, and receive input from the customer;
• a wireless transceiver communicatively coupled with the MTU control circuit, wherein the MTU control circuit is configured to wirelessly communicate and wirelessly receive at least instructions from a separate and remote central computer system through the wireless transceiver;
• a motorized locomotion system communicatively coupled with the MTU control circuit and controlled by the MTU control circuit, wherein the MTU control circuit is configured to control the locomotion system to transport the MTU and item container through at least the portion of the retail shopping facility enabling the customer to acquire desired products;
• and
• a plurality of location sensors detecting sensor data utilized to determine a location within the retail shopping facility in accordance with at least a two-dimensional map of the retail shopping facility;
• and
• the central computer system comprising a central control circuit communicatively coupled with a wireless central control transceiver and configured to wirelessly communicate with each of the plurality of MTUs, determine locations of each of the MTUs within the retail shopping facility, and communicate the instructions to the MTUs wherein the instructions in part are utilized by the respective MTU control circuits to control the movements of the MTUs within the retail shopping facility.
