Recently, Stanford University has designed and created a humanoid robotic diver that has recovered many of the treasures and mysteries from King Louis XIV's shipwreck, La Lune. This robot is called OceanOne and has many outstanding characteristics to what it can perform. The interesting idea for this robot came from the need to be able to discover and study coral reefs and underwater ocean life in the Red Sea, whereas obviously human divers couldn't swim more than 100 meters deep to research. In order to do this, you would have needed to find someone who could have held their breath for long periods of time. (Of course, so far, this is impossible to do so). This discovery stayed out of range for many divers and researchers. This was when the idea for OceanOne sparked in the minds of many engineers and skilled deep-sea archaeologists from the University of Stanford.
The students and researchers control this humanoid in a boat with a large set of monitors and joysticks. (It seems like they are playing a video game.) Basically, it is a virtual diver that is controlled by the people themselves. Because of this, the researchers at Stanford were able to use the OceanOne to dive more than 100 meters deep into the Red Sea. The OceanOne has several cameras, sensors, mini computers and much more advanced technology, that is absolutely waterproof. The OceanOne was able to dive deep to the sea grounds to the underwater site where the ship La Lune, sank. This humanoid was able to discover many of the unfound artifacts. In fact, according to news.Stanford.edu, the OceanOne was able to recover an accent vase from the shipwreck, since 1664. There are more artifacts to be found in other discoveries related to ones like these.
