An underwater thruster is a configuration of marine propellers and hydraulic or electric motor built into or mounted to an underwater robot as a propulsion device. These give the robot movement and maneuverability against sea water resistance.
ROV at work in an underwater oil and gas field. The ROV is using a torque wrench to adjust a valve on a subsea structure.. A remotely operated underwater vehicle (ROUV) [citation needed] or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general ...
Underwater videography – Electronic underwater photography concerned with capturing moving images; Surveyor's measuring tape – Flexible ruler used to measure size or distance; Vernier calipers – Moderate precision linear measuring tool; Spirit level – Tool to indicate whether a surface is level or plumb
Diagram of how a Buoyancy Engine works. A buoyancy engine is a device that alters the buoyancy of a vehicle or object in order to either move it vertically, as in the case of underwater profiling floats and stealth buoys, or provide forward motion (therefore providing variable-buoyancy propulsion) such as with underwater gliders and some autonomous aircraft.
Nemo Power Tools is the first manufacturer of a full line of power tools that are pressurized to work under water for boating, scuba and other deep sea activities. [1] [2] The company also uses the same technology to manufacture a clean room drill, the GRABO lifter and a special-ops line of underwater tools. The company was founded by Nimo ...
The hydraulic pump in turn powers the thrusters and hydraulic components of the ROV. This is referred to as an electro-hydraulic system. ROPOS is unusual as it is routinely modified to work in three different ranges: 1000 m (540 fathoms); 4000m (2,187 fathoms); and (rarely) 5,000 m (2,700 fathoms). [ 3 ]

Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
