Problems solved by technology

When the order fulfillment process utilizes only human operators to place and pick items, requiring operators to do a lot of walking can be inefficient and time consuming
Since the efficiency of the fulfillment process is a function of the number of items shipped per unit of time, an increase in time reduces efficiency

Embodiment Construction

[0021] refer to figure 1 , a typical order fulfillment warehouse 10 includes shelves 12 filled with various items that may be included in an order 16 . In operation, an order 16 arrives at the order server 14 from the warehouse management server 15 . The order server 14 communicates the order 16 to a robot 18 selected from a plurality of robots roaming the warehouse 10 .

[0022] figure 2 A typical robot 18 shown in includes an autonomous wheeled base 20 with a lidar 22 . The base 20 also features a transceiver 24 that enables the robot 18 to receive instructions from the order server 14 and a camera 26 . Base 20 also features a processor 32 that receives data from lidar 22 and camera 26 to capture information representative of the robot's environment, and memory 34 that cooperates in performing various tasks associated with navigating within warehouse 10. Tasks and navigation are placed on the fiducial markers 30 on the shelves 12, such as image 3 shown in . A fiducia...

Abstract

A method for performing tasks on items located in a space using a robot, the items being located proximate fiducial markers, each fiducial marker having a fiducial identification. The method includesreceiving an order to perform a task on at least one item and determining the fiducial identification associated with the at least one item. The method also includes obtaining, using the fiducial identification of the at least one item, a set of coordinates representing a position of the fiducial marker with the determined fiducial identification, in a coordinate system defined by the space. The method further includes navigating the robot to the coordinates of the fiducial marker associated with said determined fiducial identification.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and is incorporated herein by reference to U.S. Application Serial No. 14 / 815,246, filed July 31, 2015, which was filed concurrently with the U.S. Patent Application No. 14 / 815,110 is related. technical field [0003] The present invention relates to robotic navigation using semantic mapping, and more particularly, to robotic navigation using semantic mapping for robotic navigation throughout a warehouse with a robot-assisted product order fulfillment system. Background technique [0004] Ordering products over the Internet for home delivery is an extremely popular way of shopping. Fulfilling these orders in a timely, accurate and efficient manner has been logistically challenging, to say the least. An "Order" is created by clicking the "Checkout" button in the virtual shopping cart. The order includes a list of items to be shipped to a specific address. The process of "fulfillme...
