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.

Map creation method of mobile robot and mobile robot

The present disclosure discloses a map creation method of a mobile robot, including establishing a rectangular coordinate system in a working area of the mobile robot; causing the mobile robot moving in acharacter shape in the working area; obtaining a key frame picture of the mobile robot at a point Pi and saving the picture and coordinates of the point Pi; obtaining a picture of the mobile robot at a point P'i, wherein an abscissa or ordinate of the point P&#x2032;i is the same as that of the point Pi; extracting and matching features of the pictures acquired at the point Pi and the point P&#x2032;i; calibrating coordinates of the mobile robot at the point P&#x2032;i and data of the odometer and/or the gyroscope according to the matching result and saving them; and repeating the obtaining to the calibrating until the map creation in the working area is complete.

Map creation method for mobile robot and path planning method based on the map

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.

Mobile mechanism and mobile robot having same, and mobile method

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.
