The PUB, a water agency of the Singapore government, announced on January 15 that it will put a machine swan in each of Singapore's five reservoirs to monitor changes in water quality in real time.

The machine swan named NUSwan was jointly developed by PUB with the Environmental Research Institute and the Tropical Marine Science Institute of the National University of Singapore.

Researchers at the National University of Singapore believe that machine swan is a cheaper and simpler option than existing water quality monitoring methods. At present, in Singapore, government departments mainly rely on manual sampling of water samples to monitor the water quality of reservoirs and freshwater lakes.

Each machine swan is equipped with a mini-water collection device and a water quality detector. When researchers find that the real-time feedback data is abnormal, they can remotely control the swan to collect a certain sample of water at the site and send it back to the laboratory for analysis. . The research team believes that this new monitoring system will help government departments understand the relationship between micro-ecosystems and water quality.

PUB plans to launch machine swan in five reservoirs in Marina, Punggol, Serangoon, Pandan and Kranji in Singapore. The development time of the first three reservoirs is short, and they hope to better understand their water quality through the monitoring of the robotic swans. In the latter two reservoirs, the number of algae is often increased during the dry season, and the water quality changes need to be monitored more closely.

The National University of Singapore’s research team has also developed another robot MantaDroid. This devil-like robot can monitor the status of underwater ecosystems. When used in conjunction with the NUSwan, it can more comprehensively monitor the water quality changes of the cited sources.
