Roland Piquepaille writes "A British robotic submarine, Isis, has a very busy schedule these days. Last January, it was taking a 3-week Antarctic dive. In May, it was exploring a giant canyon just off the coast of Portugal. Its next mission will be the exploration of the Whittard Canyon, another deep submarine valley, this time off the coast of Ireland. This deep-diving remotely operated vehicle (ROV) looks like a van. It is 2.7 meters long, 2 meters high and 1.5 meters wide, it weighs 3,000kg and can dive down to 6,500 meters. But this van has enough equipment to take high-quality videos of sharks appearing at an unusual depth of 3,600 meters... But read more for additional details about this robotic submarine and see how how it is equipped to take clear pictures in the deep ocean."
