Robot finds 300-yr-old ship with treasure worth $17 billion
An autonomous underwater robot called the REMUS 6000 has discovered a Spanish galleon ship that sunk in 1708 along with gold, silver and emeralds that could be worth as much as $17 billion. The robot, which was deployed in June 2015, found the shipwreck nearly 2,000 feet below the surface. It scanned the seafloor using long-range sonar.
