Singapore recruits swanbots to test water quality

From BBC - January 15, 2018

Robot swans are taking to the waters of Singapore in order to test the quality of its reservoirs' drinking water, it's reported.

According to Channel News Asia, five fake birds are being set loose on reservoirs serving the city state to monitor water quality as part of the aptly named SWAN project (Smart Water Assessment Network).

They have been designed to look like real swans so that they will blend in with their surroundings, the news website says. While gracefully drifting along on the surface, underneath is a system of propellers and water sampling equipment, and they use wireless technology to send real-time results to national water agency PUB.

Professor Mandar Chitre of the National University of Singapore, part of a team that designed the swanbots, told CNA: "We started with a number of smaller bird models, before we decided on the swan. It's just the right size.

"If you look at it in the environment, it looks just like a swan swimming around."
