Abstract: A system for condition-based maintenance of an automated storage and retrieval system includes a framework structure with a rail system 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 between rails of the rail system that are arranged on the framework structure. The rail system provides available routes for container handling vehicles handling and transferring the storage containers to and from the storage columns. At least one container handling vehicle which has a container handling platform with a set of grippers for handling the storage containers. The grid structure includes one or more ports for extracting containers from the storage grid so that the storage containers can be picked and a service station for performing maintenance on the components of the storage and retrieval system. The system further includes a plurality of sensors configured to be attached to components of the storage and retrieval system for providing condition-based information linked to parts and components of the storage and retrieval system, a service regime manager configured to retrieve condition-based information from the plurality of sensors and create a service regime based on the condition-based information linked to parts and components of the storage and retrieval system and send the service regime to a local service station where condition-based maintenance is performed, and a central computer system. The central computer system is configured to: receive the condition-based information from the plurality of sensors and decide what information is to be sent to a global computer system that is part of the system for condition-based maintenance, and further sending only the information that can be of interest to other storage and retrieval systems. The global computer system is configured to receive the condition-based information from the central computer system and determine trends regarding component servicing or changing of components and further the global computer system transfers the information on the trend to the individual central computer system's service regime manager.
