Bevy of Robot Swans Explore Singaporean Reservoirs

IEEE Spectrum Robotics Channel 

When Singapore decided that they needed a new smart water assessment network to track pollution in their reservoirs, they obviously went with a robot, because otherwise you wouldn't be reading about it here. They also decided that the robot had to be "aesthetically pleasing" in order to "promote urban livability." The answer came from researchers at the National University of Singapore (NUS), who proposed developing a Smart Water Assessment Network: Yes, that's right, a SWAN. The researchers, from NUS Environmental Research Institute and Tropical Marine Science Institute, had developed and tested a version of the swanbots back in 2016. Now they've decided to deploy them full time across five different reservoirs in Singapore, where water is a particularly precious resource.
