An automated storage and retrieval system includes an automated storage and retrieval grid and a delivery system. The automated storage and retrieval grid includes a container handling vehicle rail system and a delivery column. The container handling vehicle rail system, which is for guiding a plurality of container handling vehicles, 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, which first and second sets of rails form a grid pattern in the horizontal plane including a plurality of adjacent container handling vehicle grid cells. Each container handling vehicle grid cell includes a container handling vehicle grid opening defined by a pair of neighboring rails of the first set of rails and a pair of neighboring rails of the second set of rails. The delivery column is adapted for transport of a storage container arranged in a stack of storage containers beneath the container handling vehicle rail system between a container handling vehicle and a delivery port situated at a lower end of the delivery column. The delivery system includes a remotely operated delivery vehicle. The remotely operated delivery vehicle includes a vehicle body, rolling devices connected to the vehicle body, rolling device motors for driving the rolling devices in a horizontal plane, and a power source connected to the rolling device motors. A container carrier is adapted to support the storage container. The delivery vehicle is further adapted to transport the storage container between a delivery port and a second location for handling of the storage container by at least one of a robotic operator and a human operator.
