A robot, robotic systems, and methods for conducting a subterranean operation. In some embodiments, a robot may include a hazardous atmosphere controlled volume, such as an explosive (EX)-certified chamber, that is located within the body of the robot. In some embodiments, a robot may include a cooling system that is at least partially disposed to fully disposed within the body of the robot, such as partially to fully disposed within the EX-certified chamber located within the body.

Robotic system including an internal cooling system

A system including an elevator to move a tubular, the elevator including two or more remotely operable latches that can configure the elevator to handle various tubular diameters. A portion of the latches can be laterally offset from each other and another portion can overlap adjacent latches. The elevator can be Atmosphere Explosible (ATEX) certified or International Electrotechnical Commission for Explosive Atmospheres (IECEx) certified according to explosive (EX) Zone 1 requirements with an electronics enclosure contained within a sealed chamber. The elevator can be rotated greater than 90 degrees relative to a pair of links that support the elevator. The elevator can use rotary actuators to operate the latches and rotate the housing of the elevator.

Elevator with a tiltable housing for lifting tubulars of various sizes

Elevator with independent articulation of certain jaws for lifting tubulars of various sizes

A system including an elevator to move a tubular, the elevator including two or more remotely operable latches that can configure the elevator to handle various tubular diameters. Each jaw can include a locking mechanism that engages a portion of the housing adjacent a spacer ring in the elevator when the first jaw is in the engaged position and configured to transfer a closing force to the housing. A portion of the latches can be laterally offset from each other and another portion can overlap adjacent latches. The elevator can be explosive (EX) Zone 1 certified with an electronics enclosure contained within a sealed chamber. The elevator can use rotary actuators to operate the latches and rotate the housing of the elevator. The elevator can use a circular pressure sensor to determine weight of a tubular.
