The grid structure forms vertical storage columns each having a horizontal area defined by the size of an access opening of the vertical storage columns. The framework structure comprises a rail system arranged above the storage columns. The method comprises checking if there are free spaces along at least one of the edges of the grid of the storage and retrieval system, checking if there are enough free spaces in the non-edge cells of the grid of the storage and retrieval system to perform normal operations, and performing rearranging if there are free spaces along at least one of the edges of the grid of the storage and retrieval system and there is not enough free spaces in the non-edge cells of the grid of the storage and retrieval system to perform normal operations.

An automated storage and retrieval system includes a storage grid provided by a framework structure arranged in a building under a ceiling. The framework structure includes a rail system arranged at an upper level of the framework structure. The rail system includes a first set of parallel rails arranged in a horizontal plane and extending in a first direction, and a second set of parallel rails arranged in the horizontal plane and extending in a second direction which is orthogonal to the first direction. The first and second sets of rails form a grid pattern in the horizontal plane including a plurality of adjacent access openings/grid cells. The storage grid defines a plurality of storage columns. Each storage column being arranged to store a respective stack of storage containers. The storage columns are located beneath the rail system. Each storage column is located vertically below a respective access opening/grid cell. Container handling vehicles operate on the rail system to collect and return storage containers to and from storage columns. A control system monitors and controls the automated grid storage and retrieval system. A method for monitoring the automated storage and retrieval system includes: launching a flying drone equipped with a camera to an altitude in an airspace located between an upper surface of framework structure and the ceiling or roof obstacle beneath the ceiling, navigating the drone to a suspected location of an anomaly in the system or other aspect of the system in need of inspection, using the drone to locate the anomaly or aspect of the system in need of inspection, and performing a visual inspection of the anomaly or aspect of the system in need of inspection using the camera of the flying drone. The control system includes an exception handler module responsible for identifying and attempting to correct anomalies in the operation of the storage system, and a flight control module responsible for controlling the flight of the drone. The flight control module directs the flight of the drone in response to instructions received from the exception handler module.

A control system controls an automated storage and retrieval system to perform a method including receiving a plurality of orders in an order list; allocating each order to one of a plurality of pick-up entities; ranking the plurality of orders in the order list according to time received; estimating, for each order, a preparation time for preparing and delivering the order to a pick-up point for pick-up by the allocated pick-up entity; estimating, for each order, a pick-up time at which the allocated pick-up entity will be ready to pick up the order based on information about the allocated pick-up entity; comparing, for each order, the estimated preparation time and the estimated pick-up time; updating the ranking of the orders in the order list so that each order will be delivered at the pick-up point at a time within a predetermined time interval overlapping the estimated pick-up time of the allocated pick-up entity; and controlling the automated storage and retrieval system for preparing and delivering the orders of goods at the pick-up point according to the updated ranking of orders in the order list.

Movement is controlled of a plurality of container handling vehicles on a rail system arranged at least partially across a top of a framework structure of an automated storage and retrieval system, on which rail system the plurality of container handling vehicles are operable to raise storage containers from, and lower storage containers into, storage columns arranged in rows between upright members and horizontal members of the framework structure. The storage containers are also transported above the storage columns. The movement control is performed by a central operational controller which is in communication with a local controller in each container handling vehicle. The central operational controller receives data relating to a subsection of the rail system. The data includes a container handling vehicle movement threshold for the subsection. The central operational controller instructs a container handling vehicle to follow a path which takes in at least a part of the subsection. The central operational controller instructs the container handling vehicle to reduce speed and/or acceleration such that the movement of the container handling vehicle within the subsection is below the container handling vehicle movement threshold of the sub section.

A remotely operated delivery vehicle for transport of a storage container includes a vehicle base, rolling device motors, a power source, a container carrier, and a rotational drive. The vehicle base includes rolling devices configured to move the remotely operated delivery vehicle in a horizontal plane along tracks of a rail system. The rail system includes a first set of parallel rails arranged in a first direction and a second set of parallel rails arranged in a second direction perpendicular to the first direction. The rolling device motors drive the rolling devices. The power source is configured to provide propulsion power to the rolling device motors. The container carrier is supported by the vehicle. The container carrier is configured to receive the storage container from above and/or from a side and onto or at least partly into the container carrier. The rotational drive is configured to rotate the container carrier, and any storage container supported thereon, relative the vehicle base.

An automated grid based storage and retrieval system includes a framework structure and a plurality of storage containers. The framework structure includes upright members and a grid of horizontal rails provided at upper ends of the upright members. The framework structure defines a storage volume including a plurality of columns arranged in a grid pattern below the horizontal rails between the upright members. The plurality of storage containers are stacked vertically in stacks in the columns to provide a plurality of storage columns. An under-stack void extends beneath the stacks of storage containers. A plurality of inlets lead to the under-stack void between the stacks of storage containers. At least one column, which is empty of storage containers and arranged amongst the storage columns, provides a ventilation column. The ventilation column includes a fan. A plurality of duct walls surrounding the ventilation column define a duct having a first end adjacent the horizontal rails and a second end adjacent the under-stack void. The fan is arranged to circulate gas along sides of the stacks, via the plurality of inlets and the under-stack void, and through the duct.
