Collaborative order fulfillment systems and methods

A method for order fulfillment within a logistics facility, the method comprising:

• receiving, at a central server, a plurality of item orders each including at least one item to be picked;
• generating, at the central server, a robot task list comprising a list of stop locations within the logistics facility, and a first picker task list comprising a first item in one or more item orders of a group of item orders assigned to a robot, a number of the first item to be picked, a location of the first item within the logistics facility, and an identity of the robot;
• sending, from the central server, the robot task list to a processor of the robot;
• calculating, at the robot processor, a route to each of the stop locations within the logistics facility and sending output control signals to a drive system of the robot for autonomous navigation to a first stop location in the list of stop locations;
• sending, from the central server, the first picker task list to a processor of a user device worn or carried by a first human picker;
• receiving, at the central server, a scan signal from the user device of the first human picker, wherein the scan signal includes information from a read by the user device of any one or more of:
• an item ID tag on the first item, a shelf ID tag on a shelf holding the first item, and a bin ID tag of a bin in which the first item is stored on the shelf;
• receiving, at the robot processor from the central server, an instruction to illuminate a subset of indicators on a platform of the robot to designate a target tote positioned on the platform and a first number of the first item to be placed in the target tote by the first human picker;
• illuminating the subset of indicators on the platform of the robot and displaying the first number of the first item;
• and
• receiving a verification signal indicating the first item is received in the target tote, and sending the verification signal to the central server,
• wherein the robot receives items from a plurality of human pickers and each human picker delivers items to more than one robot, and
• wherein the central server determines timing for sending the first picker task list to the first human picker based on a location of the robot.
