Patent attributes
An autonomous moving machine system continuously maintaining moving machines thereof at higher reliability is provided. Each moving machine measures a self-location thereof with a sensor thereof, and autonomously moves to a target location by controlling a mover. Operations of the moving machine includes acquiring sensor information, estimating the self-location in accordance with the sensor information, calculating the reliability of the self-location, transmitting the reliability to the other moving machine. Operations of a particular moving machine further includes recording history information that associates the reliability, the self-location, and an identifier identifying each of the moving machines, selecting a moving machine to restore the reliability in accordance with the history information and moving the selected moving machine to a location where the reliability of the selected moving machine increases.
