So, according to the researchers, the robot is able to function in the Mariana Trench, the deepest part of the ocean. It is noted that conventional underwater robots need waterproof enclosures of metallic materials in order to withstand the high pressure in the ocean depths. However, in the new robot, all fragile electronic parts are integrated and distributed in soft silicone, so it does not need a pressure-resistant housing.

Initially, the robot was tested in a chamber with water under pressure, then it was tested in a lake at a depth of 70 meters, in which it swam freely, developing a speed of 3,16 centimeters per second. Subsequently, it was also tested in the South China Sea at a depth of about 3200 meters and finally in the Mariana Trench.
