Mobile vehicles in manufacturing

A system comprising multiple mobile vehicles configured to move autonomously in a smart factory environment at which a work piece is processed, each of the mobile vehicles comprising:

• a spatial localization system for deriving a location of the mobile vehicle (5) in the manufacturing environment;
• an autonomous navigation and propulsion unit configured for providing mobility of the mobile vehicle in the manufacturing environment;
• a communication interface providing a data link to at least one other mobile vehicle or to a fog or cloud computation and storage system;
• and
• an edge computation unit for a local data analysis at the mobile vehicle by intelligent, deployable edge analytics software agents and configured to interact via the communication interface,
• wherein an automatic deployment of a workflow information for the processing of the work-piece for the mobile vehicles is established via the communication interface, which workflow comprises at least one current task,
• wherein at least one of the mobile vehicles is configured as a mobile measurement vehicle comprising at least one spatial measurement sensor unit, which mobile measurement vehicle is configured to autonomously navigate to a location in the smart factory environment and to establish a temporary instance of a local spatial reference cell in the smart factory environment, the temporary instance of the spatial reference cell comprising the work piece and at least one of the mobile vehicles and is established with data from the at least one spatial measurement sensor unit,
• wherein the temporary instance of the spatial reference cell is established temporarily for a limited time of a duration of a current task that has to be established at the work piece, and
• wherein the temporary instance of the spatial reference cell is established according to individual spatial requirements derived from the current task that has to be established.

A method for manufacturing a work piece at a manufacturing environment by a system comprising at least one autonomously moving mobile vehicle, the method comprising:

• autonomous localization and navigation of the at least one mobile vehicle in the manufacturing environment by a spatial localization system and a propulsion or mobile driving unit;
• and
• establishing a data link by a local edge computation unit with a communication interface to at least one other mobile vehicle or to a fog- or cloud-computation and storage system,
• wherein the at least one mobile vehicle is configured as a mobile measuring vehicle comprising at least one spatial measuring sensor unit, and
• wherein the mobile measuring vehicle temporarily establishes an instance of a local spatial reference cell, the establishing comprising data from the at least one spatial measuring sensor unit of the mobile measurement vehicle,
• wherein the establishing is temporally limited for a duration of a current task that has to be established at the work piece and which spatial reference cell is thereafter dismissed, and
• wherein the establishing of the temporary instance of a local spatial reference cell is done with an individual level of spatial accuracy and an individual local range, which individual level is dynamically defined by an accuracy requirement of the current task that has to be established.
