Robotic Swans help Monitor Water Supplies in Real-time

Tracking pollution in water reservoirs can be challenging, but engineers at the National University of Singapore developed robot swans to do it. They called the robots the New Smart Water Assessment Network or NUSwan that can measure water supplies in countries without the need for an intensive labor force and in the process, hurting the pleasing appearance of the reservoirs.

NUSwan robots can collect real-time samples of water supplies and take specific measurements such as pH level, chlorophyll, and turbidity. The data and measurements collected can be transmitted real-time, as well as via wireless network available within the range. The design of the robots features a considerable level of sturdiness to withstand minor impact damage from kayaks and other boats.

“The robotic swans swim around lakes and reservoirs and measure water quality parameters. The data collected is available in real time over the cloud to experts from water management agencies, so that they can respond to any water quality related issues promptly,” said Mandar Chitre, an associate professor in the Department of Electrical and Computer Engineering at NUS.

Because of the real-time feature, the robots can update the authorities on sudden changes, such as the onslaught of an unusual amount of algae in reservoirs. The robots can also help the authorities notify the public about water supplies that are unsafe to drink. While there are already five robotic swans in certain lakes and reservoirs, the researchers will still need support to make the project a global endeavor. Other improvements are being planned as well, such as new sensors and capabilities on the drone, more upgrades on its controls and data analytics, and the ability to warn fleets of the swimming swans.
