Abstract: Disclosed are a method and apparatus for a movable robot to adjust the pose of a goods rack. A particular embodiment of the method comprises: acquiring a goods rack identifier image of a target goods rack; identifying a pose identifier of the target goods rack from the goods rack identifier image, and determining the current pose of the target goods rack based thereon; in response to the difference between the current pose of the target goods rack and a preset pose being greater than a preset deviation threshold value, determining that the target goods rack has shifted; generating a transport path on the basis of the difference between the current pose of the target goods rack and the preset pose; and sending the transport path to a movable robot, such that the movable robot adjusts the current pose of the target goods rack.

Abstract: Disclosed is an indexable face milling cutting insert which comprises an insert body and a cutting body laminated on an upper surface of the insert body, and the insert body comprises multiple positioning side surfaces, an upper plane, and a positioning bottom surface; a projection of an edge of the positioning bottom surface, or an extension line thereof, on a rake face is intersected with a corresponding edge of the rake face, or an extension line thereof, to form a surface deflection angle and multiple flank faces are arranged between the rake face and the multiple positioning side surfaces, so as to avoid damaging the positioning side surfaces when a cutting edge is sharpened, thereby ensuring stability and long-term effect of a positioning reference, and a face cutting milling and a wiper face milling are applicable to a same face milling insert retaining slots.

Abstract: The embodiments of the present invention relate to optical communication technologies, and provide a method, an apparatus, and a unit for detecting a fault of a submarine device. The apparatus includes: a pair of optical couplers that are respectively set on two optical cables for transmitting optical signals in opposite direction and are configured to receive or send optical detection signals through the optical cables, where: the two optical couplers are connected through an optical fiber that transmits an optical detection signal, and a photosensitive component is set on the optical fiber and is configured to adjust an optical parameter of the optical detection signal by perceiving change of an ambient environment state parameter when a fault occurs. The embodiments of the present invention bring benefits of detecting whether a target submarine device is faulty, and locating a cause for the fault of the submarine device accurately.
