|Argus and Little Hercules|
Little Hercules is a "Remotely Operated Vehicle," or ROV, intended primarily for gathering high quality video images of underwater artifacts. There are no people on board, but Little Hercules allows a pilot and other observers on shipboard to experience visiting the bottom of the ocean almost as though they were there.
Little Hercules has a buoyancy module to make it neutrally buoyant in seawater. That means its density is close to that of seawater, so gravity has little effect on the vehicle when it is submerged, and a small downward force from the thrusters will drive the vehicle toward the bottom.
Four thrusters allow the pilot to maneuver Little Hercules freely, as long as the tether going back to Argus doesn't come taut. The length of the tether is about 30 meters (100 feet). Little Hercules carries a very special, High Definition video camera to provide as much detail as possible to the observers on the ship and elsewhere.
Argus and Little Hercules were used in the Mediterranean in 2003 to explore ancient shipwrecks and trade routes.
