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.

Abstract: A mobile mechanism, a mobile robot having the mobile mechanism and a method for moving the mobile robot are disclosed. The mobile mechanism includes a housing in which a guide portion is provided, a sliding seat mounted on the guide portion and movable along the guide portion, a moving wheel fixed on the sliding seat and partially protruding beyond a surface of the housing, a pressing portion pressing against the sliding seat and moving the sliding seat toward the surface of the housing; and a deformation portion mounted on the housing and connected with the pressing portion, exerting a force for moving the sliding seat towards the surface of the housing through the pressing portion when deformed.

Abstract: The present disclosure discloses a method for planning a path of a mobile robot including an odometer and a gyroscope. The method includes causing the mobile robot to move from an initial position to a point Pi or a point P?i, calibrating data of the odometer and/or the gyroscope at the point Pi or the point P?i, and repeating S?1 to step S?2 until arriving at a final target point.

Abstract: Methods for angle correction of a mobile robot in a working area and mobile robots performing the same are disclosed. In one example, a long straight line is obtained at an edge of an obstacle first found by the mobile robot. A right-angle coordinate system is established based on the long straight line. A walking angle of the mobile robot is obtained when the mobile robot finds a long straight line at an edge of an obstacle again. Based on the walking angle and the right-angle coordinate system, the walking angle is corrected to a corresponding axis direction.
