A drilling assembly that can include a first mast, a second mast, a water table coupled between the first and second masts, and a plurality of sheaves coupled to the water table and adapted to translate along a plane oriented generally perpendicular to a height of at least one of the first or second mast. A drilling assembly that can include a mast having a generally C-shaped support structure, as viewed from a top view, and an opening disposed within the support structure, where the mast is disposed adjacent to a wellbore, and where the opening is adapted to permit passage of tubulars from an external position to the wellbore through the mast. A drilling assembly that can include a mast, a water table coupled to the mast, and a drawworks disposed adjacent to the mast, where the drawworks is adapted to laterally translate relative to the mast.

A system, includes a movable platform slidingly coupled to one or more supports and configured to be selectively moved towards a drill floor and away from the drill floor. The system also includes a roughneck disposed on the movable platform and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment. The system additionally includes a support member disposed on the movable platform and configured to support one of the first tubular segment or the second tubular segment as the movable platform is selectively moved towards a drill floor or away from the drill floor.

A linkage assembly for a drilling machine includes a first arm, a second arm, an actuation member, and a connector assembly. A first end of the first arm is pivotally coupled to a positioning member at a first pivot joint. A first end of the second arm is pivotally coupled to a feed table at a second pivot joint. A first end of the actuation member is pivotally coupled to the feed table at a third pivot joint. The connector assembly is fixedly coupled to a second end of the first arm, and pivotally coupled to a second end of the second arm and a second end of the actuation member. The linkage assembly is adapted to pivot the feed table relative to the positioning member about a pivot axis based on movement of the actuation member between an extended position and a retracted position.

A system for conducting subterranean operations is disclosed and can include a tubular storage area, a well center area, and a robotic arm configured to move tubulars. The robotic arm can be coupled to a rig floor and configured to traverse a distance between the well center area toward the tubular storage area.
