An automated warehouse system and method are provided for controlling the internal microclimate of receptacles within a warehouse or order fulfilment facility. The system provides independent environmental condition monitoring and regulation for each tote. The system enables individual totes to be maintained at adequate or substantially ideal conditions, independent of its position within a storage system or the environmental conditions of adjacent totes in the storage system. The totes may include self-contained environmental control systems and/or the storage system may include environmental control inputs to adjust or maintain the environmental conditions within a particular tote. The system is operable to monitor and control the microclimate of a tote while it is stored at a storage location within the storage system or in a buffer, and may be operable to monitor and/or control the microclimates of the totes while they travel throughout the system.

A system and method is provided for controlling an automated warehouse or order fulfillment facility. The system includes a sequencing tower, which functions as a buffer for inbound items and shipping containers, and various pick/decant workstations which are connected between the sequencing tower and an automated storage and retrieval system (ASRS). The sequencing tower is adapted for receiving, storing, and releasing newly erected shipping containers and inbound vendor cases. The pick/decant workstations function as a hub between the sequencing tower and the ASRS, where operators at the pick/decant workstations pick order items to shipping containers to fulfil orders or pick inbound/vendor items to inventory containers to be stored in the ASRS. The system and methods synchronize the sequencing tower and ASRS to release items to arrive at the workstations simultaneously to optimize efficiency and throughput of the facility.

An automated warehouse material movement system and method of moving material in a warehouse, includes a computer based warehouse executive subsystem (WEX) that is programed with computer code to maintain inventory location and quantity information, schedule inventory movement and track inventory movement within the warehouse and a computer based mobile robot automation subsystem (MAS) that is programed with computer code to maintain information of floor layout of the warehouse, maintain information on mobile robots in the warehouse, allocate and deallocate mobile robots to particular missions, control and track movement of mobile robots and provide situational reporting of the mobile robots. A computer based vehicle tasking subsystem (VTS) is programed with computer code to respond to mission commands from the WEX to issue commands to the MAS to reserve and schedule mobile robots including movement of inventory between a source and a destination within the warehouse and to report status information from the MAS to the VTS regarding status of missions. At least one microservice component is configured to be tightly designed, stateless and loosely coupled with said WEX and MAS. The VTS is the at least one microservice component.

A confirmation system including a touchless sensor and method for confirming that an order fulfilment operation has been performed. The system includes at least one touchless sensor to sense or recognize a gesture given by an operator, wherein the gesture confirms that a desired operation has been performed. The touchless sensor is connected to a workflow control system configured to transmit order fulfilment information to and from the touchless sensor. The touchless sensor is configurable to recognize a plurality of gestures, and may be configured to recognize those gestures at a plurality of distances away from the touchless sensor. The touchless system is configurable to provide alerts to operators to indicate locations requiring action. The confirmation system may be provided with a cubby or bin order fulfilment system. Additional features include placement or retrieval sensors, cubby illumination lights, pick-to and put-to lights, and information scanners.

A system and method for consolidating order items into individual or batch orders within an order fulfilment workstation and discharging the order items to a takeaway device, such as a trackable segmented conveyor. The system includes a temporary holding container at the workstation and a discharge mechanism to release or transfer the contents of the temporary container to the takeaway device. The system and method reduce or eliminate the process of an operator replenishing order transport containers to the workstation once a completed order container has dispatched from the workstation. Empty order containers are supplied the workstation via the takeaway device. The empty order container is positioned adjacent the temporary container such that the discharge mechanism may transfer the order items from the temporary container into the empty order container. The discharge mechanism may transfer the order items directly to the surface of the takeaway device.

A sound attenuated material handling element reduces vibration and sound in a material handling system. The material handling element may be a sound attenuated roller for use in a roller conveyer or a sound attenuated nestable tote for receiving and transporting articles in the material handling system. Reducing vibration in material handling element reduces the noise produced by the element. The sound attenuated roller includes sound attenuating material disposed inside of the roller and in contact with the inner surface of the roller body. The sound attenuated nestable tote includes sound dampening material disposed in or formed with the tote structure. The sound damping material may be integrally formed with the roller or tote in order to maximize vibration and noise attenuation. Three dimensional computer analysis may be used to determine optimized locations for placement of the sound damping material on the roller or tote.

Methods and systems are provided for verifying a pick/put operation within an order fulfilment workstation or a storage rack. An optical device observes an operator performing a pick/put operation at the workstation. An indicia is located on the operator such that it is visible to the optical device. Image data of the indicia captured by the optical device is transmitted to a control system of the workstation. The control system determines a relative location of the indicia and then determines the location at which an item was picked from or put to relative to the workstation within a high degree of positional accuracy. The method verifies that the operator has completed the assigned pick/put operation at the required location. The methods and systems may be adapted to track or monitor relative positions of mobile and stationary equipment in an automated warehouse.
