An automated storage and retrieval system comprising a storage grid for storage of storage containers and a delivery system for transport of said storage containers between a delivery port of the storage grid and an access point of the delivery system, the access point being adapted for handling of items held in the storage containers by a robotic operator or human operator, and the delivery port being the port in which the storage container enters or exits the storage grid, wherein, the delivery system comprises: - a delivery rail system comprising at least a first set of parallel rails arranged in a horizontal plane and extending in a first direction, and at least 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 together defining a delivery grid of delivery grid cells, - the access point, and - a remotely operated delivery vehicle comprising a motorized vehicle body and a container carrier provided above the motorized vehicle body for carrying a storage container of the storage containers, and wherein the delivery vehicle is moveable on the delivery grid of the delivery rail system, wherein the delivery grid provides one or more delivery grid cells for the remotely operated delivery vehicle at the access point as well as a plurality of delivery grid cells adjacent the one or more delivery grid cells of the access point, such that there is more than one path to and/or from the access point for the remotely operated delivery vehicle via the plurality of delivery grid cells, and wherein the remotely operated delivery vehicle is arranged to transport the storage container from the delivery port of the storage grid across the delivery grid to the access point and return it to the delivery port for storage within the storage grid, characterised in that the access point is provided in a container accessing station, said station being arranged for separating the robotic or human operator from the delivery rail system and the remotely operated delivery vehicle, wherein the container accessing station comprises a cabinet comprising walls and a top cover supported thereon, wherein the items held in the storage container carried by a remotely operated delivery vehicle at the access point is reachable through an opening in the top cover. wherein, the delivery system comprises: - a delivery rail system comprising at least a first set of parallel rails arranged in a horizontal plane and extending in a first direction, and at least 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 together defining a delivery grid of delivery grid cells, - the access point, and - a remotely operated delivery vehicle comprising a motorized vehicle body and a container carrier provided above the motorized vehicle body for carrying a storage container of the storage containers, and wherein the delivery vehicle is moveable on the delivery grid of the delivery rail system, - a delivery rail system comprising at least a first set of parallel rails arranged in a horizontal plane and extending in a first direction, and at least 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 together defining a delivery grid of delivery grid cells, - the access point, and - a remotely operated delivery vehicle comprising a motorized vehicle body and a container carrier provided above the motorized vehicle body for carrying a storage container of the storage containers, and wherein the delivery vehicle is moveable on the delivery grid of the delivery rail system, wherein the delivery grid provides one or more delivery grid cells for the remotely operated delivery vehicle at the access point as well as a plurality of delivery grid cells adjacent the one or more delivery grid cells of the access point, such that there is more than one path to and/or from the access point for the remotely operated delivery vehicle via the plurality of delivery grid cells, and wherein the remotely operated delivery vehicle is arranged to transport the storage container from the delivery port of the storage grid across the delivery grid to the access point and return it to the delivery port for storage within the storage grid, characterised in that the access point is provided in a container accessing station, said station being arranged for separating the robotic or human operator from the delivery rail system and the remotely operated delivery vehicle, wherein the container accessing station comprises a cabinet comprising walls and a top cover supported thereon, wherein the items held in the storage container carried by a remotely operated delivery vehicle at the access point is reachable through an opening in the top cover.
