ROV Hercules always operates in tandem with another vehicle, Argus. Referred to as a "tow sled", Argus dangles at the end of a cable from the ship. Because Argus lacks a buoyancy module and is built of heavy stainless steel, its movements are controlled by moving the ship or raising and lowering the cable. A short 30 meter (100 foot) tether connects Hercules to Argus, but it is usually kept slack so Hercules can move around without being pulled by the ship. Argus carries an HD video camera similar to the one on Hercules, as well as large lights that illuminate the area around Hercules. Argus allows the pilots and scientists to view Hercules' surroundings from above. Thrusters on Argus control its heading, so the pilots can aim the video cameras and lights toward Hercules and sites of interest.
