Scientists have developed a new miniature robot that can swim with fish, learn how they communicate with each other and make them change direction or come together

Researchers at Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland developed the robot that can integrate perfectly into schools of zebrafish.

"We created a kind of secret agent that can infiltrate these schools of small fish," said Frank Bonnet, a researcher at EPFLs Robotic Systems Laboratory (LSRO) and author of the study published in the journal Bioinspiration & Biomimetics.

About the Robot spy 
The robot is seven centimetres long — longer than the fish it is modelled after but with the same shape and proportions.

It is equipped with magnets that link it to a tiny engine installed under the aquarium to propel it through the water.

The researchers chose zebrafish for their study because it is a robust species whose schools tend to switch direction and move about very quickly.

The team determined the key criteria that would allow the robot to integrate into schools of zebrafish and subsequently influence their behaviour.

These included the fishs physical characteristics, like shape, colour, stripes, etc.
 
Their behavioural characteristics were also taken into account, such as linear velocity, acceleration speed, the distance between individual fish, the size of the schools, their vibrations and motion, and the rhythm at which they move their tails.

I never knew technology is growing so fast. It is difficult to mingle with the fishes as they are very sensitive. I am waiting for the results. They will succeed.

A brainchild of The Times of India, the world’s leading English newspapers, Times NIE nurtures progress and innovation. Adapted from the international concept, Times Newspaper in Education program (Times NIE) was initiated in India in 1985.

Today we have over 3000 schools and over 9 lac students subscribing to the programme, spanning 16 cities viz. Delhi, Mumbai, Pune, Bangalore, Kolkata, Chennai, Hyderabad, Ahmedabad, Kochi, Lucknow, Coimbatore, Chandigarh, Dehradun, Vijayawada, Visakhapatnam, and Jaipur.

The Times of India Student edition, a customized student newspaper exclusively for the students, packs a powerful punch in terms of content that leads to a smarter and superior learning experience. The information is crafted such that it finds use in classroom discussions, thus making it relevant and current. It truly gives education a new dimension by fostering the simple habit of reading which in turn paves the way for a confident, informed and aware individual. A newspaper that inspires young minds and equips them to face challenges of today’s world, making way for global citizens.

Empowering students with new cutting-edge knowledge through various educative and informative activities is a commitment and tradition of Times NIE. The programme serves as a catalyst of education and interaction, as well as a window into the minds of the quintessential Indian youth. On a significant scale Times NIE comprises diverse interesting activities and events that boost the child’s passion for learning, while revealing hidden talent.

While you are aware that The Times of India is among the leading English Newspapers across the world, it has consummated its position as an everlasting winner. With several international awards and recognitions to its credit, The Times of India and Times NIE have validated an enduring tradition of setting the highest benchmarks in every respect. We have been awarded with the two most prestigious awards, Times NIE - World’s No.1 NIE program and The Times of India, Student Edition - World’s No.1 Newspaper for the youth in 2006 by the celebrated World Association of Newspapers (WAN). In 2008 we were honoured by the International Newspaper Marketing Association (INMA), yet another international recognition for ‘Youth Audience Development’. In 2013 we were again honoured by the celebrated World Association of Newspapers (WAN) as the ‘Times NIE - World’s Best Youth Engagement Program’.

Times NIE has grown remarkably over the last three and a half decades, touching millions of children across more than 16 Indian cities. Our absolute commitment towards the fledgling generation remains undiluted and our greatest strength lies in the school partnership and commitment.
