Delivery vehicle, an automated storage and retrieval system and a method of transporting storage containers between an automated storage and retrieval grid and a second location

A remotely operated delivery vehicle for transport of a storage container between a location directly below an automated storage and retrieval grid configured to store a plurality of stacks of storage containers, and a second location for handling of the storage container by at least one of a robotic operator and a human operator, the remotely operated delivery vehicle comprising:

• rolling devices configured to move the remotely operated delivery vehicle in a horizontal plane along tracks of a delivery rail system comprising a first set of parallel rails arranged in a first direction (X) and a second set of parallel rails arranged in a second direction (Y) orthogonal to the first direction (X), the first set of parallel rails and the second set of parallel rails form a grid pattern in the horizontal plane comprising a plurality of adjacent delivery vehicle grid cells;
• rolling device motors for driving the rolling devices;
• and
• a power source configured to provide propulsion power to the rolling device motors,
• wherein the remotely operated delivery vehicle further comprises a container carrier mounted on top of a vehicle body, wherein the container carrier comprises a base and side walls to form a volume configured to receive the storage container from above and contain an entire horizontal extent of the storage container and at least a part of a vertical extent of the storage container so that contents of the storage container are accessible by the at least one of the robotic operator and the human operator, and
• wherein the remotely operated delivery vehicle has a delivery vehicle footprint with a horizontal extent which is equal to or less than a horizontal extent of the delivery vehicle grid cell such that the remotely operated delivery vehicle can pass another vehicle on adjacent delivery vehicle grid cells.
