China Develops First Water-surface Cleaning USV

Jun 15, 2018

China develops the first water-surface cleaning Unmanned Surface Vehicle, or USV, according to a recent study by Institute of Intelligent Machines (IIM) of Hefei Institutes of Physical Science.

This newly designed USV, targetting at water-surface cleaning for the first time ever, is smart enough to remove surface garbage in complicated water area.

The key technologies applied in the machine help overcome problems caused by complicated conditions in both water areas and river channels.

"There are many types of USV, but the one we developed is the first  to target water surface cleaning", said Dr. YU Daoyang, a researcher of LIU Jinhuai's team working with IIM.

"For the narrow river channel, we developed a laser radar path tracking system that can accurately self-adjusted to obstacles and paths of the rivers. Actually, you know, lidars are generally used for road detection. Because the light interference on the water surface is too strong. As for that, we made intelligence algorithm to solve that", explained YU.

The water-surface cleaning USV has a total length of six meters and a maximum displacement of four tons. It possesses a garbage compartment capacity of more than three cubic meters as well as a hybrid power system with a cruising time of more than 60 hours.

Now, it has started its work in Suzhou River in Shanghai. And its use on the Bund of Huangpu River will start in the coming future.
