The National University of Singapore has developed robotic swans to monitor and test pollution levels in the city's water reservoirs. Cleverly named NUSwan, the project is designed to blend in with the natural environment, while conducting quality checks of Singapore's freshwater lakes and reservoirs. The mechanism is self-governing, as the birds use under-body propellers and specialized sensors to survey the water. Simultaneously, the active robotic swans stream the collected data in real time to the command center.
The traditional system is conducted through fixed online stations, which have far too limited coverage in certain areas. Since the aqueous environment is heavily impacted by the rate of urbanization, recreational activities and other factors, the NUS's robotic swans offer a cost-effective and more efficient system of doing quality checks for levels of dissolved oxygen and chlorophyll.
