(Xinhua) 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.
The 3.6-tonne ROV successfully collected deep-sea biological samples and sediments — with these findings taken to a supporting research vessel named Zhong Shan Da Xue.
In a significant development, this voyage also saw the simultaneous deployment of the full-ocean-depth autonomous and remotely-operated vehicle (ARV) named Haidou-1, marking the first time two distinct deep-sea unmanned submersibles had conducted coordinated scientific operations via a single supporting Chinese research vessel.
