Method for distributing navigation map data to a plurality of work machines

A work machine network comprising:

• a plurality of work machines;
• and
• a central control device operably connected to the plurality of work machines and configured to
• detect work orders for the plurality of work machines, which work orders exist in the network and were planned on the basis of old navigation map data,
• check the detected work orders to identify the work orders which can be carried out with new navigation map data,
• check the detected work orders to identify the work orders which cannot be carried out with the new navigation map data,
• terminate the identified work orders which cannot be carried out with the new navigation map data,
• deactivate the plurality of work machines, and
• install, after deactivating the plurality of work machines, the new navigation map data in the identified work orders which can be carried out with the new navigation map data after terminating the checked work orders.

A method of distributing navigation map data to a plurality of mobile robots configured to perform work orders in which goods are transported from one location to another location in an environment, the navigation map data describing a plurality of paths through the environment along which the plurality of mobile robots may travel to perform work orders, the method comprising:

• receiving, with a central control device, new navigation map data including at least one modification the plurality of paths;
• identifying, with the central control device, a plurality of work orders for the plurality of work machines that have not yet been completed and which were planned based on navigation map data that is older than the new navigation map data;
• identifying, with the central control device, a first set of work orders in the plurality of work orders that can be carried out using the modified plurality of paths in the new navigation map data;
• identifying, with the central control device, a second set of work orders in the plurality of work orders that cannot be carried out using the modified plurality of paths in the new navigation map data;
• terminating, with the central control device, the second set of work orders that cannot be carried out;
• and
• transmitting, with the central control device, the new navigation map data to those mobile robots of the plurality of mobile robots that have a work order in the first set of work orders that can be carried out.
