Many cities often make studies on a periodic basis to water its lakes or seas of its beaches, this procedure has several decades carried out through people who acquire a sample of water and bring it to a laboratory for analysis. In the best of cases, automatic collectors and sensors are placed to measure over long periods of time.
The problem with these procedures is that you neither person can be all the time taking samples of various sectors, nor is can be consulting the results of sensors on a periodic basis, at any time of the day. But this could be left behind thanks to the development of robots in the form of swans you will be able to carry out these tasks.
NuSwan, a nice robots in the form of Swan
Scientists at the National University of Singapore have developed an interesting proposal, which seeks to regularly measure the quality of the water in lakes and bays, but as they do not want to draw the attention of visitors or tourists, have decided that the robots that are responsible for this work have the form of Swan, to pass unnoticed.
These NuSwan (New Smart Water Assessment Network) are equipped with a rechargeable battery pack, electric motor, a pair of propellers, a GPS module and other WiFi, as well as sensors that are able to measure and monitor the pH, turbidity, chlorophyll content and dissolved oxygen.
The interesting thing is that each NuSwan is capable of send the results to the cloud via WiFi, so that they can be consulted remotely from various locations without being physically to the robot. You can be plotted at each NuSwan a route so that with your GPS, you measure the quality of water in certain sectors. In addition to that can be controlled manually via a remote.
Each NuSwan has the ability to “know” when your battery is almost flat, then will go to the base and charge your battery automatically, without the intervention of a person. Materials that is made of this robot, allow you to navigate in salty water and sweets, it is able to withstand extreme weather conditions and up to small craft punches.
At least in Singapore, this work was destined to about 10 people who each morning took a small boat to carry out measurements, this took about 6 hours, most other 6 in analyzing the results. With the implementation of NuSwan, they expect that the costs are reduced drastically, but above all have the information available at any time of the day.
