CNS, Shenyang, May 14 (reporter Zhu Mingyu)-14th public activities of the Chinese Academy of Sciences Branch, Shenyang Institute of automation Chinese Academy of Sciences researcher Liu Jian said representatives of China's highest level of underwater "Dragon, second" return home with the honor, achieved a major scientific breakthrough.
"Dragon, second" called "independent exploration system 4500-meter deep ocean resources." Its overall objectives are adopted a 4500-meter underwater robot system platform, covering hydrothermal anomaly detection and micro-topography measurement, underwater photography and magnetic detection techniques used in deep-sea exploration of mineral resources such as polymetallic sulphides.
According to the "Dragon, second" Liu Jian, Chief Architect introduce, after more than three months in the India Ocean to explore the ocean floor, the "Dragon, second" show stable sailing capability and collision performance. Single dives maximum detection time spent more than 32 hours, maximum depth of navigation over 3200 metres. 4 posting a long-range success probing China's largest deep water autonomous underwater robot. Filling China's deep-sea hydrothermal sulfide autonomous exploration technology and equipment, blank, successfully passed the acceptance.
Reporters saw "Dragon, second" 3.5 meters long and weighs 1.5 tons, full-bodied yellow and hang themselves each have two red "fins" propeller, shaped like a yellow fat fish.
In 1986, the Chinese developed the first underwater robot "sea first." Starting in 2010, China's rapid development of underwater robots, the "Dragon" manned submersibles at the 7000 meter level sea in trying to break the world manned submersible maximum dive depth, then no series "Hidden Dragon, first" and "Dragon, second" were published, future goal will be to conquer the Mariana Trench.
Through generations of underwater exploration, China has applied for polymetallic nodule mining area of 150,000 square kilometers of the Pacific Ocean, in Southwest India Yang applied for a 10,000 square kilometre polymetallic sulphides mining area, laying a solid foundation for understanding of the deep ocean resources.
The same day, branch of Chinese Academy of Sciences within the Institute of metal research, Institute for applied ecology, Dalian Institute of chemical physics, the Marine Institute and other units also features public science day activities, to show the social outcomes of major scientific and technological innovation, promote science literacy for all.

“潜龙二号”载誉归来 中国水下机器人实现重大突破

　　中新网沈阳5月14日电  (记者 朱明宇)中国科学院沈阳分院14日举行公众开放日活动，中科院沈阳自动化所研究员刘健表示，代表中国水下机器人最高水平的“潜龙二号”载誉归来，实现重大科考突破。

　　“潜龙二号”全称为“4500米级深海资源自主勘查系统”。其总体目标是通过一套4500米级水下机器人系统平台，涵盖热液异常探测、微地形地貌测量、海底照相和磁力探测等技术，用于多金属硫化物等深海矿产资源勘探。

　　据“潜龙二号”总设计师刘健介绍，在历经三个多月的印度洋海底探险中，“潜龙二号”表现出稳定的航行能力和避碰控制性能。其中，单次下潜最大探测时间逾32小时，最大航行深度超过3200米。4个连续长航程的成功探测创下了中国深海自主水下机器人之最。填补了中国深海硫化物热液区自主探测技术装备的空白，顺利通过各项验收。

　　记者看到，“潜龙二号”长3.5米，重1.5吨，通体鲜黄色，头尾各有两个红色“鱼鳍”型推进器，外形好像一条黄胖鱼。

　　1986年，中国研制出首台水下机器人“海人一号”。从2010年开始，中国水下机器人发展迅速，“蛟龙”号载人潜水器在7000米级海试中打破世界同类型载人潜水器最大下潜深度，接着无人系列的“潜龙一号”和“潜龙二号”也先后面世，未来目标将征服马里亚纳海沟。

　　通过几代水下机器人的探测，中国已在太平洋申请了15万平方公里的多金属结核矿区，在西南印度洋申请了1万平方公里的多金属硫化物矿区，为了解深海资源奠定了坚实基础。

　　当日，中国科学院沈阳分院系统内的金属研究所、沈阳应用生态研究所、大连化学物理研究所、海洋研究所等单位也就各自特点举办公众科学日活动，向社会展示重大科技创新成果，提升全民科学素质。
