An automated storage and retrieval system includes a rail system with a first set of parallel rails extending in a first direction and a second set of parallel rails extending in second direction. The second direction is perpendicular to the first direction. The system includes a plurality of container handling vehicles on the rail system operable to handle storage containers. Each container handling vehicle includes a positioning node and a local controller adapted to control movements of the container handling vehicle. The system includes a positioning system comprising at least three reference positioning nodes spaced in fixed positions on and/or proximate the rail system. The positioning system is adapted to determine a position on the rail system for each of the container handling vehicles based on signal measurements between the positioning node of each container handling vehicle and the at least three reference positioning nodes. A control system is adapted to communicate with each local controller in each container handling vehicle and the positioning system. The control system is adapted to: instruct a first container handling vehicle to move to a target position, repeatedly receive position data from the positioning system of a position of the first container handling vehicle and repeatedly receive position data from the positioning system of a position of a second container handling vehicle, and instruct the second container handling vehicle to move with and follow the first container handling vehicle within a predetermined separation from the first container handling vehicle based on the received position data of the positions of the first and second container handling vehicles.

A container handling vehicle with a cantilever solution operates on an automated storage and retrieval system. The automated storage and retrieval system includes a framework structure forming a three-dimensional storage grid structure for storing storage containers for storing items. 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. A rail system is arranged on the framework structure, rails of the rail system extending in an X-direction and a Y-direction to define a grid and to define a perimeter of each access opening on top of each storage column. The rail system provides available routes for container handling vehicles handling and transferring the storage containers to and from the storage columns. Each rail has a first track and a parallel second track allowing two container handling vehicles to pass each other using the same rail. Each vehicle communicates with a central computer system controlling the operation. At least one container handling vehicle has a container handling platform with a set of grippers for handling the storage containers. The wheels are on a cantilever side of the container handling vehicle, used for manoeuvring the container handling vehicle in the Y-direction, are positioned or are positionable with respect to the container handling vehicle to allow them to use an outer track of a rail in the Y-direction to manoeuvre the container handling vehicle when the wheels on an opposite side of the container handling vehicle are using an inner track of an adjacent rail in the Y-direction.

A method handles malfunctioning vehicles on a track system constituting part of a storage and retrieval system configured to store a plurality of stacks of storage containers. The track system forms a grid pattern of adjacent cells. The storage and retrieval system includes a plurality of remotely operated vehicles configured to move laterally on the track system, wherein each of the plurality of remotely operated vehicles comprises driving wheels, and a control system for monitoring and controlling wirelessly movements of the plurality of remotely operated vehicles. The control system performs at least the following steps by wireless data communication: detecting an anomaly in an operational condition of a vehicle on the track system, registering the vehicle with the anomalous operational condition as a malfunctioning vehicle, registering a halt position of the malfunctioning vehicle relative to the supporting track system, and setting up a two-dimensional shutdown zone on the track system. The setting up a two-dimensional shutdown zone on the track system includes a malfunctioning vehicle zone including the halt position of the malfunctioning vehicle, and an entrance zone for entry into the malfunctioning vehicle zone. The entrance zone extends between the malfunctioning vehicle zone and a location at a periphery of the track system. The control system further performs ordering the remotely operated vehicles in operation within the shutdown zone to either move out of the shutdown zone, a halt or a combination thereof, and indicating allowance of entry into the entrance zone for an external operator by at least one of: unlocking a gateway at the periphery, and producing an entry-allowed signal registrable by a human operator located at the periphery such that the human operator may enter the entrance zone through the gateway.

The invention relates to a storage system, which comprises at least one station (2), such as a station for receiving goods, for re-shelving goods, picking goods and/or supplying goods from the store, and a high-bay warehouse (3) having a plurality of storage places (31) arranged adjacent to and on top of each other for the storage of goods, wherein the storage system (1) comprises at least one displaceable goods transport vehicle (4) which is designed to transport at least one item from the station (2) to any storage place (31) or vice versa, without reloading the goods onto a different goods transport vehicle (4) or another means of transport. The invention is characterized in that the goods transport vehicle (4) is designed to move in the horizontally oriented area between the station (2) and the high-bay warehouse (3) for transporting the goods as well as horizontally and vertically in the high-bay warehouse (3).
