This Day, That Year

Editor's note: This year marks the 40th anniversary of China's reform and opening-up policy.

With the development of submarine technology in recent decades, the nation has witnessed its submarine industry booming and it has also emerged as a leader in terms of underwater exploration.

An item in China Daily shows that China's first underwater robot, HR-01 (Seaman-01), built by the Shenyang Institute of Automation in Liaoning province in 1985, picked up designated objects from 200 meters below the sea's surface in 1990.
