A LIDAR device is positioned on a crane and is moved along a track to collect 3D image data of the area below the crane. The resulting image data is sent to a computing device that applies or more filtering algorithms to the image data and searches for known image shapes therein through a comparison of the image data and one or more 3D object models based on known shapes or geometric primitives. If an object is identified in the image data and is determined to be accessible, position information for that object may be sent to a device configured to control movement of the crane to grab/pick up the object.

A measurement device measures a frequency response of a servo system, applies predetermined oscillation are associated with each other to the servo system, identifies, from a result of oscillation application, a pair of a first oscillation application signal and a first response signal, and identifies a pair of a second oscillation application signal and a second response signal. Then, a first frequency response that is a frequency response is calculated on the basis of the first oscillation application signal and the first response signal, a second frequency response that is a frequency response is calculated on the basis of the second oscillation application signal and the second response signal, and the first frequency response and the second frequency response are synthesized.

A method for steering a downhole tool in a wellbore includes measuring a tool face when the drill bit is off-bottom, measuring an angular position of a drill string when the drill bit is off-bottom, and measuring a torque on the drill string when the drill bit is off-bottom. The method also includes measuring the tool face when the drill bit is on-bottom and measuring the torque on the drill string when the drill bit is on-bottom. The method also includes determining a transfer function comprising the angular position of the quill, the difference between the toolface when the drill bit is on-bottom and off-bottom, and the difference between the torque when the drill bit is on-bottom and off-bottom. The angular position of the drill string is varied at the surface, based upon the transfer function, to reduce an angle between the tool face when the drill bit is on-bottom and a target tool face.
