Switzerland, August 6, 2017: As per the Pacific Institute, more than 2 million tons of a wide range of waste is pumped into the world’s waters each day. Researchers have become great at recognizing it, however not very great at finding the source of pollution. However, Envirobot, the latest biomimetic fabrication by Swiss researchers, provides a solution.

It appears as a water snake but is actually a collection of little segments, all doing different jobs. They are taking it on a test drive around bodies of water in search of toxins and other substances which can harm aquatic animals in order to take control of water pollution.

 The segments of Envirobot are identical so that the joint can oscillate in water. The head coordinates the motion of different segments in order to create a serpentine pattern which propels the whole robot. Its job when fully developed will be to guard water bodies on its own looking for pollution and toxins.
It can also send data to computers in real time as it swims. Its tiny chambers get filled with water as the robot swims through water. Envirobot is more efficient and accurate as it can collect water from multiple spots in a lake or river. It will be used as a measure to detect metals as they can harm people and aquatic life.

Instead of having a measurement station somewhere or going out to take a sample and bringing it back to the lab, the robot will actually slither in water bodies and measure a number of water quality parameters in real time. Envirobot is better than conventional propeller-driven underwater robots as it is less likely to get in branches and algae when they move around.

Each segment of the Envirobot is unique so as to enable it to perform all kinds of water tests at the same time. For instance one segment measures very general quality parameters like temperature, conductivity, pH, oxygen level, so as to say whether water quality is good or not. Other segments carry bacteria, fish cells and even tiny water fleas that can react to toxins and insecticides in the water body.

The researchers’ ultimate goal is to create a full-time autonomous pollution sniffing robot and prevention of water pollution. What they are yet to achieve is to enable the Envirobot to by itself locate the source of the pollution. This will help to measure and decide where to go next which is a very challenging project. Given the amount of waste that is being dumped or pumped into the world’s waterways, it is a very worthy goal.
