Granted, this here project isn't nearly as inexpensive as the $100 underwater ROV from years back, but at least this one is propelled by something a bit more advanced than a pull string. Regardless, the ROV-in-a-Box Project Kit -- created by folks from Carl Hayden High School for use in the National Underwater Robotics Challenge -- is a $249.95 package that "includes all the parts needed to build a working underwater robot: a frame, motors, underwater light, camera, 50-foot tether, operator control box, and a dry-cell battery." Of course, you'll still be required to provide your own tools and TV monitor, but to take a closer look at exactly what a nickel under $250 will buy you, click on through for a detailed video (but do tap Mute beforehand, okay?).

the first ROV was developed in 1953
ROV stands for "Remote Operated Vehicle". ROV's are not submarines by definition, since they are robots controlled by tether, by an operator stationed on a support vessel.
ROV means remotely operated underwater vehicle, so the pilot isn't in the machine. The pilot is sitting at a control panel on a ship nearby.
Remotely operated vehicle
The deepest ROV has been down to depths of around 6Km or 3.75 miles.
The ROV in the movie The Abyss was a Mini Rover ROV which was designed and built by Chris Nicholson of Deep Sea Systems in Falmouth, MA in 1984. It was 26 inches long and weighed 55 pounds. The Mini Rover ROV was the world's first small, low cost ROV. Its original price was about $28,000 at a time when the next lowest cost ROV was priced at $100,000.

Figure out the weight of the device (ROV, submarine,etc), and then the weight of the water displaced. When they are equal, the device is neutrally buoyant. However, usually engineers create a ROV with a slightly positive or negative bouyancy, personally I perfer a positivly buoyant ROV because if you lose power or the tether is cut the ROV will ascend back up to the top. A more simple answer is that when the gravity & buoyancy are equal it is neutrally buoyant
In Russian, "nice to meet you" is "Приятно познакомиться" pronounced as "Priyatno poznakomitsya."
R.O.V means Remotly Opperated Vehicle
In American football, a "rover" is a defensive player who "roves" from linebacker to defensive back, or roves from cornerback to safety in the defensive bakefield. The rover has no fixed position. The abbreviation ROV stands for ROVER.
