China deployed unmanned aircraft to restore communication services and survey conditions in several parts of Central China's Henan province that were severely affected by recent heavy rain and flooding.

A Wing Loong 2H disaster-assistance drone took off on the afternoon of July 21 from the Anshun airport and flew nearly 1,200 kilometers before arriving over Henan's Mihe township. The aircraft then began to fly around the flood-stricken township to provide communication links to people using the China Mobile network.

On July 20, some 118 sets of Dolphin 1 over-water life-saving robots from Zhuhai Yunzhou Intelligent Technology were deployed to aid professional water rescue teams in Zhengzhou, Central China's Henan province.

The Dolphin 1 robot is an intelligent rescue lifeboat that can be remotely controlled. The robot is portable and easy to carry, and it can carry loads of up to 150 kilograms while also dragging three people to safety.

Pumping vehicles with equipment specialized for discharging water were used in Henan to pump and drain water and restore traffic. A rescue team of 1,800 firefighters has been deployed to the flood-hit region from seven neighboring provinces, together with boats, pumping vehicles, and flood rescue kits, according to a Xinhua report.
