The present invention discloses a mobile platform and an operating method of the mobile platform. The mobile platform comprises: a base; a housing disposed above an upper surface of the base and forming a placement space placing a work device with the upper surface of the base; and a travel mechanism disposed below a lower surface of the base for driving the housing and the base to move, wherein the lower surface of the base is provided with a groove and a bottom of the housing is disposed outside of an edge of the base. Moreover, during movement of the mobile platform, a dripping liquid drips down along the housing when the mobile platform is in an upright state, and the dripping liquid drips into the groove when the mobile platform is in an inverted state.

A plurality of sliding rails and a frame structure comprising a plurality of frame elements configured to be arranged at least partly circumferentially around a tower structure. Each frame element is slidably connected to at least one of the sliding rails, and the frame elements and the sliding rails are interconnected to form a scissor structure. An upwardly directed lifting force applied by a hoisting mechanism at connecting points at or near positions where the frame elements are connected to the sliding rails, in combination with gravity working on the frame structure, causes the frame elements to slide along the sliding rails, thereby causing the scissor structure to contract or expand to adjust a diameter of the frame structure to an outer diameter of the tower structure having the apparatus mounted thereon.

An apparatus (1) for movement along a tower structure (11) is disclosed, the apparatus (1) being configured to be arranged at least partly circumferentially around the tower structure (11). The apparatus (1) comprises a plurality of sliding rails (2) and a frame structure comprising a plurality of frame elements (3). Each frame element (3) is slidably connected to at least one of the sliding rails (2), and the frame elements (3) and the sliding rails (2) are interconnected to form a scissor structure. An upwardly directed lifting force applied, by means of a hoisting mechanism (8), at connecting points (10) at or near positions where the frame elements (3) are connected to the sliding rails (2), in combination with gravity working on the frame structure, causes the frame elements (3) to slide along the sliding rails (2), thereby causing the scissor structure to contract or expand to adjust a diameter of the frame structure to an outer diameter of a tower structure (11) having the apparatus (1) mounted thereon.

The mobile platform comprises: a base; a housing disposed above an upper surface of the base and forming a placement space placing a work device with the upper surface of the base; and a travel mechanism disposed below a lower surface of the base for driving the housing and the base to move, wherein the lower surface of the base is provided with a groove and a bottom of the housing is disposed outside of an edge of the base. Moreover, during movement of the mobile platform, a dripping liquid drips down along the housing when the mobile platform is in an upright state, and the dripping liquid drips into the groove when the mobile platform is in an inverted state.

An articulated tracked vehicle that has a main section, which includes a main frame, and a forward section. The main frame has two sides and a front end, and includes a pair of parallel main tracks. Each main track includes a flexible continuous belt coupled to a corresponding side of the main frame. The forward section includes an elongated arm. One end of the arm is pivotally coupled to the main frame near the forward end of the main frame about a transverse axis that is generally perpendicular to the sides of the main frame. The arm has a length sufficiently long to allow the forward section to extend below the main section in at least some degrees of rotation of the arm, and a length shorter than the length of the main section. The center of mass of the main section is located forward of the rearmost point reached by the end of the arm in its pivoting about the transverse axis. The main section is contained within the volume defined by the main tracks and is symmetrical about a horizontal plane, thereby allowing inverted operation of the robot.
