Given the topic for this competition as 'Facing pandemic with ideas'. We are required to develop a project based on the 17 UN sustainable development goals. After hours of research, we decided on four important goals to be dealt such as- Clean Water and Sanitation, Life below Water, Good Health and Well-being and Affordable and Clean Energy. The COVID-19 pandemic has made us realise the need for clean water more than ever since we require clean water to keep ourselves clean and healthy. We can prevent so many Water Borne diseases by purifying water and will definitely contribute in the health and wellness of a person. We came across various methods, devices to test the water quality. A technique approach and correction of any fault in the operations of such device that attracted our attention so much, we felt the need to improvise maintaining quality through standards.

What it does

It is a robot inspired from the original Water-snake robot. A robot which can navigate through any depths and is designed according to the user’s purpose, is used to test the quality of water. It also purifies the water and makes it suitable for drinking.

How we built it

we built this amphibious snake-like robot and designed in such a way that it navigates through the water with ease. It composes of cylindrical modules stabilized by flexible joints which allows free motion. To get more propelling force in the water, it consists of wheeled paddles, embedded with pollution sensors to find out the concentration of various elements. It contains electrochemical sensors to detect heavy metals such as lead and BIOSENSORS to detect bacterial presence.

Challenges we ran into

The main challenge would be to embed the sensors in such a way that it records the maximum and accurate reading of the concentration of different materials.

Accomplishments that we're proud of

We were able to record the concentration with more accuracy and managed to use solar energy, one of the cleanest and cheapest energy source to run our device. We implemented AI and collect data in the most efficient and effective manner.

What we learned

We definitely learnt how we can use our engineering skills to tackle problems in the society and help the world in anyway we could. We learnt about the working of motor and implementing AI in water purification process. And we definitely learnt to work as a team.

What's next for Portable water testing and purifier Robot

For now, the water can be mainly used for domestic purposes (which includes washing hands, which is very important during this pandemic). We are still working on increasing the efficiency to make it 100% pure, drinkable water and we definitely feel it is possible.
