In 2015, the company took the lead in developing a set of 500 ton/day seabed polymetallic nodule mining robots. Adopting independent patented filtering mining sorting technology, the mining and sorting process can be completed in one go, with efficient and stable operation. 3000 meter underwater filtration mining work efficiency 300-400m ³/ h. The single lifting weight of the platform reaches 4000 tons, and the lifting speed of the ore box reaches 1m/s. Becoming the world’s first commercially successful underwater filtering mining robot.
