    摘要: The robot lawn mower that executes lawn mowing work while autonomously running includes: a positional information acquisition unit for acquiring positional information; a slip rate acquisition unit for acquiring a slip rate indicating a slip degree; a storing unit for storing control information in which the positional information acquired by the positional information acquisition unit and the slip rate acquired by the slip rate acquisition unit are associated with each other; and a running control unit for controlling the autonomous running based on the control information stored in the storing unit.

    摘要: A technology for improving a positioning precision is desired in a case where a positioning precision of a positioning signal is relatively low. A location estimation apparatus includes a sub area extraction section configured to extract one or more sub areas including at least a part of a region defined by a location and an error range indicated by positioning information, a precision parameter extraction section configured to refer to map information in which area identification information is associated with a precision parameter indicating a positioning precision and extract, with regard to each of the one or more sub areas extracted by the sub area extraction section, the precision parameter, and an output section configured to output the sub area where the positioning precision indicated by the precision parameter is equal to or worse than the positioning precision indicated by the positioning information, as a location of a moving object.

    摘要: To make it possible to correct a current position detected by an autonomous traveling work machine to the correct position with a simple configuration. A robot lawn mower includes a first position detecting unit for detecting a current position by using odometry and a second position detecting unit for detecting a current position by using an image capture. When position detection accuracy of both of the first and second position detecting units decreases to less than or equal to a predetermined value, the robot lawn mower is controlled to travel to either of zones Z1 and Z2 in which the position detection accuracy of the second position detecting unit is relatively high, and when the robot lawn mower moves to either of the zones Z1 and Z2, a current position used for autonomous traveling is corrected to the current position detected by the second position detecting unit.
