  • Patent number: 11485013
    Abstract: The present disclosure discloses a map creation method of a mobile robot, the mobile robot working indoors, comprising the following steps: S1: obtaining Euler angles of a current point relative to a reference point according to a ceiling image taken from the current point and the reference point; S2: determining whether the roll angle of the Euler angles is lower than a set value, if so, saving the map data of the current point, otherwise, not saving the map data of the current point; S3: returning to step S1 after the mobile robot moves a predetermined distance or for a predetermined time; S4: repeating steps S1 through S3 until the map creation in the working area is complete. The present disclosure also discloses a mobile robot using the above method.

Compared with the prior art, the technical solution of the present disclosure effectively determines whether the mobile robot deflects on the working surface and deletes the map data with errors when the mobile robot deflects, thus improving the map creation accuracy of the mobile robot.
