Underwater ROVs are often positioned and controlled by using

Explanation:
Thrusters are the primary means of moving and orienting an underwater ROV. By carefully varying the output of multiple thrusters, the vehicle can push or pull in any direction, translate in three dimensions, and rotate about its axes. This active control lets the ROV reach and hold a specific position or follow a path, even in currents, using feedback from sensors like depth, IMU, and sonar. The tether (cables) mainly supplies power and data, not actuation, while sonar and manipulator arms serve sensing and manipulation roles rather than driving the vehicle’s position.
