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 first 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, the delivery rail system comprising:
• a first set of parallel rails arranged in a first direction;
• and
• a second set of parallel rails arranged in a second direction orthogonal to the first direction,
• wherein 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;
• a power source configured to provide propulsion power to the rolling device motors;
• a container carrier configured to receive the storage container from above and onto or at least partly into the container carrier so that contents of the storage container are accessible by the at least one of the robotic operator and the human operator;
• and
• a displacement device configured to tilt the container carrier about a pivot axis oriented parallel to at least one of the first direction and the second direction,
• wherein the container carrier comprises a base plate and a plurality of vertical side walls configured to restrict movement of the storage container and a height of the plurality of vertical side walls is equal to a height of the storage container.
