China’s self-developed Haiqin, a 6,000-meter deep-sea remotely operated vehicle (ROV), has successfully completed a deep-sea voyage in the South China Sea, scientists have told Xinhua.
The deep-sea electric ROV system named Haiqin, which was designed and built by Shanghai Jiao Tong University, reached a depth of 4,140 meters during the sea trial early on Saturday morning.
Equipped with high-definition cameras, robotic arms, sonar systems and sensors — the ROV demonstrated capabilities including automatic heading control and precise hovering.
