A group of treasure hunters may have solved one of the richest mysteries in the world, with help from a robot.
It's thought that as much as $10bn (£5.6bn) of gold coins and jewels may have been uncovered on an island near Chile named after Robinson Crusoe.
It's thought the treasure was taken from South America around 300 years ago by Spanish sailors.
People have searched for the loot ever since, but now a robot that scans below the island's surface has found it.
The treasure has been found on Robinson Crusoe island, which is also known as Juan Fernandez island.
In the year 1704 a Scottish sailor called Alexander Selkirk was stranded on the island and survived for four years on his own.
His story was turned into a book in 1729 by the author Daniel Defoe, who decided to rename Selkirk Robinson Crusoe.
