Researchers at the Delft University of Technology in the Netherlands have created a new drone that is designed to find and test for harmful algae in the water.
The drone uses a hyperspectral camera to scan the water for any form of algae or other particulates that could be dangerous. When it detects something, it lands on the surface of the water and takes a sample, however, the drone is also fully submersible and it is able to dive down to take samples at a lower depth.
It then automatically lands back on the flow cytometry which can analyse the sample and produce results. This is great as it saves time and money in trying to rush the samples back to a laboratory for testing.
