US Patent 10162368 Autonomous moving machine

An aspect of the present disclosure relates to an autonomous moving machine which may maintain the self-location with high reliability. Operations of the moving machine include acquiring sensor information about the self-location, estimating the self-location based on the sensor information, calculating the reliability of the estimated self-location, recording the reliability in association with the estimated self-location. When the reliability satisfies a given condition, the operations include moving the moving machine to a position at which the reliability is high, based on the reliability.
