Powerful enough to lift 1,000 pounds，capable of going where no man can go and able to stop a flowing oil well，a team of undersea robots have become known as superheroes in the effort to stop the oil pouring into the Gulf of Mexico.
The underwater remote-operated vehicles are able to stand 5,000 pounds of deepsea pressure in the Gulf of Mexico.They can also lift a ton，take photos，and they are the best-equipped vehicles in the world.“They are very active and they are playing a very vital role in everything we do，”BP spokesman Mark Salt said in a statement.“People can’t be down there，but these robots can do.”
Robots are working 5,000 feet below sea level to help contain the leak(泄漏)，which has poured out millions of gallons of oil into the Gulf of Mexico since the Deepwater Horizon，a kind of off-shore drilling(钻孔)equipment operated by BP，blew up on April 20，killing 11 workers.
The cameras that provide the data are attached to the robots as they work around the leaking
site.They made news this week when one robot bumped into a cap that had been collecting some of the oil，forcing BP to remove it for about 10 hours and leaving the flow into the Gulf unchecked.However，there’s been only one other problem in two months，despite their demanding tasks.
The most popular remote-operated vehicle is known as the “ROV”and is being used in the project.It’s 11.5 feet long and weighs 8,000 pounds.It has human-like arms and its wrists can work continuously like a drill.Jeffrey Harris，an employee from Oceaneering International Inc，which provided about 14 robots to work in the Gulf，said，“It’s like a construction worker，but it is doing one of the most demanding jobs in the world.”
