Stanford "Marine One" humanoid robot seeks shipwreck from the 17th century

In April of this year, Oussama Khatib, a professor at Stanford University in the United States, led a research team to conduct underwater expeditions on the southern coast of France, 30 kilometers away, aiming for a shipwrecked French king, Louis L. XIV, in the 17th century. The sunken ship is located more than 100 meters deep under the water, which is where most divers are difficult to reach. Thus, Oussama Khatib wanted to use a customized humanoid submarine robot to help the team accomplish this goal. This robot is called Ocean One. It is reported that in the latest December issue of the IEEE Robotics and Automation (RAM), Stanford University's research team described details of how they designed and produced Ocean One, and how it allowed it to find La Lune's place to sleep. The Ocean One is a hybrid of humanoid robots and underwater ROVs, but it is better than ROV in many ways. It is even smaller, about one-fifth in height, and closer to a live diver, and more flexible. You can use a three-fingered hand to hold a vase.
The Ocean One's more human-like design allows people to operate it underwater more intuitively through a remote monitoring interface. Everyone may not be familiar with ROV. At present, most marine ROVs are box-shaped submarines. Fortunately, there may be a robotic arm. However, for underwater archeology, these submarines cannot be completed due to the need for more accurate detection. If the diver is to be sent to the sea, once the water depth exceeds 40 meters, the danger and complexity will be greatly increased. In addition, Ocean One's more human-like design allows people to operate underwater tasks more intuitively through a remote monitoring interface. The Ocean One is specifically designed for precise operation in confined spaces. It has a total of 8 thrusters that can automatically stabilize in the water stream.
For underwater robots, one of the biggest research difficulties is the high pressure environment in the ocean. Because all its joints are connected by hardware and move with each other, it is no small challenge to maintain coordination and balance in a high-pressure environment. In this regard, Professor Oussama Khatib stated that the team used Oil-filled Structures. When the external water pressure increases, the oil inside the robot will also increase the pressure. As a result, the pressure inside and outside the Ocean One will be maintained. Consistent. In this way, the firmware in the multi-joint system is protected. All in all, Ocean One is a unique and impressive project that demonstrates the great potential and potential of human and robot cooperation. Just as to prove the possibility of human and robot collaboration. As Bram Vanderborght, editor-in-chief of the IEEE Journal of Robotics and Automation, puts it, "Cooperating with humans, robots will surely outweigh solutions that use machines instead of humans."

Matte Film
