The team of the Blue Harvesting project completed the first series of tests of the Apollo 2 robot, intended for d b b They carried out south of Malaga at an underwater test site at a depth of 300 m. The robots were satisfied – its activity did not cause any harm to health, which was the main disease upon detection of the car.
Metallic nodules include such nuggets of metals as nickel, cobalt, manganese and copper, which are found in abundance in bottom sediments of various parts of the World Ocean. This resource is in great demand, but the problem is that most of the nodules lie in the silt at great depths, so their extraction raises large volumes of bottom rocks. Huge sheifs msora and dust
The Apollo 2 robot sucks in sludge along with metal nuggets, filters it, but not only throws out the waste material, but pre-compacts it. Then the sludge is neatly placed on the place where it was taken from. During the tests, the appearance of very rarefied plumes was observed, most of the soil lingered on the bottom, an increase in the volume of movement was not desirable – there was a goal to achieve. Now the robot is waiting for a test already in deep water, at a depth of several kilometers.
