Singapore is a unique place with a non-standard and innovative approach to literally everything. When the task here was to introduce new methods for assessing water quality, the authorities organized an open collection of proposals. Many of the proposed solutions were related to robotics, but their appearance left much to be desired, and the aesthetics of the devices was among the priorities for the state. The best proposal came from researchers at the National University of Singapore (NUS), they developed the Smart Water Assessment Network (SWAN, Intelligent Network) project. water assessment). In collaboration with the Institute of Tropical Marine Sciences, NUS experts have created functional devices for evaluating water that look like a pair of swan robots. Swan robots, called NUSwan, are already exploring the water in five reservoirs in Singapore. Such a decision allowed not only to improve the ecological situation, but also to make public spaces more aesthetic and interesting. Previously, water research was carried out in the most elementary way – this was done by people on boats. But such a course of research was quite expensive and not very effective, so the idea with robot swans was welcomed favorably. The devices are quite durable, they are not damaged and do not fail when colliding with small boats. To study the quality of water in one reservoir, 5-6 robotic swans are enough. Devices are launched into the water, where they autonomously for several consecutive hours without recharging collect information from all corners of the reservoir, analyzing many indicators at once (pH, dissolved oxygen, turbidity, etc.). All received measurements are immediately transferred to scientists over a wireless network to a cloud service for real-time analysis. Such an organization of water monitoring allows you to quickly take measures to improve water quality, if any indicators do not meet the standards.
