Earthshot Prize 2021 finalist Vinisha Umashankar ‘irons’ out a plan to save the Earth

Written by: Charu Thakur

(January 12, 2022) “We have every reason to be angry. But I have no time for anger. I want to act. I am not just a girl from India. I am a girl from Earth and I am proud to be so,” smiled the pint-sized bespectacled Vinisha Umashankar at the United Nations Climate Change Conference (COP26) in Glasgow. The student innovator, environmentalist, entrepreneur and optimist had Prince William, and other world leaders in awe. Suddenly, a toothy 15-year-old Indian environmentalist was in the reckoning.

However, this native of Tamil Nadu is not ready to rest on her laurels, and demands action. “All of us should understand that environmental issues are real and can’t be fixed later. Most importantly, they are not someone else’s problem. We all must work together to understand environmental problems and solve them before it is too late. Today’s actions matter tomorrow,” says Vinisha, who is one of the eight baton-bearers to carry the Commonwealth Games 2022 torch in India from January 12 to 15, 2022.

Being the youngest and the only school student to earn a spot among the finalists for The Earthshot Prize 2021, the TEDx speaker was invited by Prince William, The Duke of Cambridge, to speak at the World Leaders’ Summit at the COP26 in November 2021. Such was the impact of her five-minute speech that global leaders like US President Joe Biden, British Prime Minister Boris Johnson, Bill Gates, and PM Narendra Modi gave her a standing ovation. Vinisha’s plea has since gone viral with over 30 million views.

Enriched to be in the company of the minds whose innovations and solutions are making an impact on Earth, she was apt and self-assured. “COP26 was quite critical because we have to plan actions for the next 10 years, and execute them together for a better future. I am keen to take forward what I learnt to make the Earth better,” adds the Dr APJ Abdul Kalam IGNITE Award winner (2019).

Thinking beyond fossil fuels

Her invention of a solar-powered ironing cart became the lodestar. She was just 12 when she started designing her innovation after the idea struck when accompanying her mother to deliver ironing clothes.

The Solar Ironing Cart

Seeing six ironing vendors in her neighbourhood, Vinisha saw how charcoal burning is a serious threat to the environment. “They use charcoal to heat an iron box, and usually throw the burnt charcoal away with the garbage. It made me think about the number of ironing carts in India, the amount of charcoal burnt every day, and the damage done to environment,” says the SKP Vanitha International School student, who found her “eureka” in solar power which effectively substitutes charcoal. “Using renewable solar energy is the aim of my innovation,” Vinisha says in an exclusive with Global Indian.

Cleaning the air, making us breathe

The innovation won her the Children’s Climate Prize in 2020, and helped her get a slot as a finalist at The Earthshot Prize in the Clean Our Air category in 2021. “I was happy that environmental innovations like a solar ironing cart got due recognition. It can play a crucial role in reducing environmental damage and climate change. I hope my innovation motivates students to innovate on products that could help protect the environment for future generations. I am happy that the solar ironing cart is my little contribution towards an ambitious goal,” says the confident young inventor.

Vinisha Umashankar won the Children’s Climate Prize 2020.

Vinisha’s invention is built on an integral-type chassis, the ironing cart, “can be fitted with a coin-operated GSM PCO, USB charging points, and provide mobile recharging services. The solar panel doubles as the roof of the ironing cart,” she adds.

The girl who reads too much

Born in 2007 in Tiruvannamalai (Tamil Nadu), her business consultant father and school teacher mother realised how fascinated she was by science and maths as a child. They are the wind beneath her wings, and her biggest support system. “My parents bought me many books to read, and explore,” reveals the Class 10 student, who often accompanies her parents to museums, zoological parks, botanical gardens, palaces, and forts. Her love for Nature and environment stemmed from these visits, and to country farms and animal asylums.

As one of the eight baton bearers from India to carry the Commonwealth Games torch and a participant at the Vibrant Gujarat Global Summit, she is also preparing for her boards. How she strikes a balance between the acclaim, endeavours and studies evokes a smile. Her time management skills, she explains, “I sort my scholastic and co-scholastic activities a day or week in advance. I prepare a to-do list, and finish it one by one. I schedule everything meticulously so that I don’t spend too much time on a single activity – all done a little at a time rather than in one long slot! However, I listen to music, go for a walk, exercise and relax in between activities.”

A tale of many talents

Despite her hectic schedule, Vinisha finds time to unwind curling up with a book, cycling or trying her hand at photography. A yoga and gymnastics enthusiast, she has a Grade 4 electronic keyboard certification from Trinity College London too.

Having accomplished so much so young, she advises youngsters “to believe.” “If you think that you can move a mountain with your fingers, believe that you can. What other people think of you is irrelevant. No one is in charge of your future, but you. Gain knowledge around your passion and strengths. Develop a unique set of skills that work. It is better to try and fail than just dream about achieving great things! You learn a lot by doing things and even more by failing. Do not fear failure. That’s how great people have done it,” adds the teenager, who wants to become a research scientist or a theoretical physicist in the future.

Next on agenda for the Earth Day Network Rising Star 2021, is, “To manufacture the solar ironing cart. Also, over the years, I have given over 100 interviews, 40 innovation talks, and 40 motivation speeches to over 25,000 school and college students. I will continue to inspire young minds to create an environmentally-conscious society,” says the committed teen activist.

Anmol Tukrel: AI healthcare for a better world

(April 22, 2023) Each time he came to India with his family, Anmol Tukrel would visit his aunt, who worked at a hospital for the visually-impaired. He saw the widespread poverty, the lack of awareness and access to quality healthcare, and decided to something about it. Anmol went on to create iDentifi, an AI healthcare app that allows visually impaired people to get information about their surroundings. This was in 2015, in the early days of AI and his efforts saw him featured in a video alongside Canadian Prime Minister Justin Trudeau and Geoffrey Hinton, the 'father of deep learning', along with a host of other young Canadian innovators. Building iDentifi "In India, the hospital staff would go to small towns and villages and offer free eye care to those who couldn't afford it," Anmol said. The next breakthrough also came in India, this time during an internship at a startup named IceCream Labs. "They were using computer vision, the same technology as iDentifi, for advertising. I thought, why not apply it to more humanitarian purposes," he said. The app could identify 96 languages - Anmol's method at the time was to look at a world map at his parents'

technology as iDentifi, for advertising. I thought, why not apply it to more humanitarian purposes," he said. The app could identify 96 languages - Anmol's method at the time was to look at a world map at his parents' home in Markham, Canada, and use pins to identify the countries in which the app was being used. The app is also on display at one of Canada's leading science museums.

The app was meant to provide as much detail as possible. In one demonstration video on YouTube, the user, Jason Fayre, the National Lead for Accessibility and Assistive Tech for CNIB, asked the app to identify a can of coke - "Pop cans are tricky," he explained. The app was able to tell the difference between a can of Coke and Coke Zero. "There are similar apps but iDentifi is more accurate and can provide an abundance of information, which sets it apart," said Fayre, who is also visually-impaired.

Finding success

As users could simply download the app from the app store, it gained popularity fairly quickly. The app proved useful "for day-to-day tasks, reading and browsing the web," the Global Indian said. "For example, if they went grocery shopping and wanted to find out if the can of soda they were holding was Coke or Pepsi, normally they'd have to find someone and ask, however with iDentifi, they can just take a picture of the can and get an audible description with a few seconds."

[caption id="attachment_29460" align="aligncenter" width="292"] Markham, Ontario teen Anmol Turkel wins Ontario Science Centre's 2017 Weston Youth Innovation Award for his AI healthcare app, iDentifi, that assists the visually impaired in identifying objects using a smartphone.

A search engine to take on Google

Born and raised in Markham, Anmol was interested in technology from a young age. By the time he turned 16, he was building a personalised search engine, intended to take on Google itself- that was his submission to the Google Science Fair. For this, Anmol used a computer with around 1GB of storage space, a spreadsheet programme, a Python-language development settings and some articles from the New York Times to get himself going. A couple of months of design work and about 60 hours of coding later, his prototype was ready.

To test the accuracy of his creation, he limited his search queries to articles from the New York Times, creating fictitious users with different interests and corresponding web histories. This information was fed to the search engine and to Google as well. Anmol submitted his paper to the International High School Journal of Science. He hoped his efforts would take him to Stanford University, which they did. There, he studied computer science and AI. These days, Anmol actually works for Google - he's an Associate Product Manager for Gmail's AI team and before that, was an APM intern on the Google Podcasts team.

Diabetes PD

Still captivated by the AI for healthcare space, Anmol went on to design Diabetes PD, this time targeting teenagers with Type-1 diabetes. "It's meant to make it easier to keep track and access quality information to manage diabetes," he explained. It allows the user to access resources that are updated in real time, and include travel, employment, meal planning and how to take care of oneself when one is sick. Users can also keep track of information related to diabetes care, monitor sugar levels, and A1Cs, to name a few.

Anmol Tukrel's story is a powerful reminder of the potential of technology to solve real-world problems. His creation, iDentifi, has already made a significant impact on the lives of visually impaired people around the world. Anmol's passion for technology, his dedication to his work, and his belief in the power of young people to make a difference have made him a role model for many.

Diana awardee Aanya Rao’s Art Connect is brightening up the lives of patients in Singapore

(August 7, 2022) While accompanying her father to health centres during his second kidney transplant in 2018, fourteen-year-old Aanya Rao did not appreciate the dull hues of the space. “They should be bright enough,” to infuse some positivity into the minds and lives of the people already in a sombre mood, she thought. Struck by the absence of vibrancy, the youngster delved into research on the impact of art in the healing process. It was then that the idea of Art:Connect germinated. “For many patients, special needs children, healthcare workers, and senior citizens hospitals and care centres have almost become like home. It is very important for them to have a vibrant and positive environment,” she tells Global Indian, while connecting from Singapore. [caption id="attachment_20476" align="aligncenter" width="852"] Aanya Rao, founder Art:Connect[/caption] From hobby to purpose Aanya had always been in love with art, learning the nuances of fine arts since the time she was a seven-year-old.

From hobby to purpose

Aanya had always been in love with art, learning the nuances of fine arts since the time she was a seven-year-old. It was during the hospital visits with her father that she realised that the hobby can be utilised for a larger purpose. In 2020, she laid the foundation of the student-led body Art:Connect, and since then, the teenager along with 40 plus student volunteers studying in schools and colleges of Singapore, have been working in tandem to put their artistic talent to good use. To eliminate the starkness of the white walls, they coloured them up with murals in health care centres, displayed their handmade creations in exhibitions to raise funds, and organised art workshops and competitions for patients and senior citizens.

[caption id="attachment_20481" align="aligncenter" width="892"] A mural by Art:Connect team at Vanguard Healthcare, Singapore[/caption]

The Art:Connect team also conducts art workshops for mothers and their children suffering from lysosomal storage disorder, and diseases like phenylketonuria, thalassemia and osteogenesis. They have organised exhibitions to spread awareness about organ donation, dementia and mental health, and have been making greeting cards to brighten up the lives in hospitals during festivals. “While we started with brightening up walls, our initiative branched out into other areas connecting art with well-being,” says the teenager.

The team finds immense satisfaction in the fact that their creativity has not only got an audience but has been replacing gloominess with vibrancy. With their slogan, ‘Art can, and will, heal the world’ they have been leveraging the “healing power of art” to brighten lives of not just those who are suffering but also of the healthcare workers and caregivers who work in the emotionally, physically and mentally draining environments.

[caption id="attachment_20480" align="aligncenter" width="897"] Art:Connect organised a special workshop in collaboration with Rare Disorders Society Singapore (RDSS)[/caption]

Future ahead

To keep on adding a healing touch is what Aanya never wants to lose focus of. The 16-year-old, Class XI student of NPS International School Singapore, is working on succession planning and building the next step of leadership as she comes closer to her foray in the world of university education.

The Art:Connect team collaborates with about 500 students across schools of Singapore for special projects. “Moving on from a core team of five, I will play a more advisory role,” informs the teen about her non-profit’s future plan.

Avi Gupta: Indian-American teen revolutionises healthcare with affordable ventilator invention

(September 13, 2023) "I want to take you back to March 2020. The coronavirus had landed in the United States. Social distancing entered into our vocabulary. Schools were closed and store shelves were empty. Against this backdrop, Europe grappled with its first wave of coronavirus. One of the key shortages they faced - ventilators," that's how Avi Gupta opens his TedX speech. The Indian American from Portland reveals that the US, especially Oregon, too faced a similar situation with a shortage of hundreds of ventilators for the critically-ill covid patients. That's when Oregon Health Authority reached out for help from many individuals and companies, including INTEL. However, it didn't take the responsibility of designing and manufacturing a ventilator, instead the request was filtered down to the senior staff of the company, one of whom happened to be a manager of Avi at a former internship. That's how the Stanford University student joined a team of doctors, researchers, and fellow engineers to co-found LifeMech, a non-profit that builds low-cost ventilators. Such has been the impact of his work that he was awarded the Truman Scholarship 2022 for his commitment to public service. [caption id="attachment_24322" align="aligncenter" width="481"] Avi Gupta played a key

Avi Gupta played a key role in developing low-cost ventilator[/caption]

Then an 18-year-old, Avi helped design the ventilator's user interface, as amid the crisis, "rapid development and deployment of the technology were essential." Interestingly, he wasn't just the youngest member of the team but also the reigning Jeopardy Teen Tournament champion. "The original prototype which was fully functional was made in our garages. So, it's truly something that can be deployed worldwide," the Global Indian said in an interview.

Avi, who switched to Stanford to pursue his interests in artificial intelligence and public policy after a year of college at Columbia University's School of Engineering, knew that the prototype had to be scalable in both design and manufacture. But more than anything it had to be "low-cost and open source to be deployed in communities worldwide." "What it meant that anybody like a doctor or a non-profit in another country could download our designs and code and easily manufacture the ventilator with the parts available in their country," he added.

[caption id="attachment_24323" align="aligncenter" width="546"] Avi Gupta is currently studying at Stanford University.[/caption]

Though he found the process of designing the interface stressful, he also found it equally rewarding as it could have a direct impact on someone's health. Avi, who collaborated with his father, Dr Saurabh Gupta, a cardiologist for the making of the ventilator, said that the project epitomises the work that he wants to do - using technology to solve a bigger problem. "It's using technology to advance public service," he told the Stanford Daily. Later, the ventilator was approved by the Federal Drug Administration (FDA) and used widely during the ventilator shortage.

Apart from this, Avi is also involved in Public Interest in Tech (one of the groups on the Stanford campus) which focuses on fostering conversations around technology's role in society. Since his school days, Avi has been keen to make a change, so when he won the 2019 Jeopardy Teen Tournament, in honour of the host Alex Trebek, he donated a part of his winnings ($100,000) to raise awareness and fund early pancreatic cancer research. He partnered with OHSU Knight Cancer Institute to create and lead the #InspiredBy campaign, raising over $225,000.

It was in 2016 that he kickstarted his journey towards creating social impact when he founded Project 32, a student-run social startup that uses the power of education to tackle dental diseases in youth. Since its inception, Project32 has provided thousands of dental hygiene kits to children in the US, India, Guatemala, and Haiti.

In his free time, he loves to play chess and basketball and is a huge Portland Trail Blazers fan.

From Delhi to Stockholm via Madras: The journey of Mannat Kaur’s award-winning greywater project

(September 18, 2024) A few years ago, when Mannat Kaur witnessed her home tap run dry, she began exploring solutions for the widespread use of greywater (domestic wastewater) to address the water crisis. Little did she imagine that her curiosity and efforts to develop a water-conservation project would eventually lead her to being felicitated by the Princess of Sweden, and attend the Royal Banquet hosted by Sweden's King Carl XVI Gustaf. The 16-year-old, class 12 student spent an unforgettable week in Stockholm this August when she travelled to represent India at the 2024 International Stockholm Junior Water Prize, held as part of World Water Week. Winning the national championship at IIT Madras, which led to these remarkable experiences, had already been a golden opportunity in itself. [caption id="attachment_39296" align="aligncenter" width="482"] Mannat Kaur at the royal banquet[/caption] Accompanied by her father and the national organizer, Prof. Indumathi M. Nambi from the Department of Environmental Engineering and School of Sustainability at IIT Madras, Mannat joined participants from 30 countries for the prestigious event. Although the United Kingdom took home the international prize, the experience has filled Mannat, the Head Girl of DPS RK Puram, with immense confidence and unforgettable memories. 'Every moment

and School of Sustainability at IIT Madras, Mannat joined participants from 30 countries for the prestigious event.

Although the United Kingdom took home the international prize, the experience has filled Mannat, the Head Girl of DPS RK Puram, with immense confidence and unforgettable memories. 'Every moment was unforgettable,' she tells Global Indian.

The joy of being a national champion

IIT Madras served as the national organizer for World Water Prize. Mannat competed against 350 applicants from 23 states at the national level and emerged as the winner, earning the opportunity to represent her country. “The top 12 shortlisted teams were invited to present their projects in person at the IIT Madras campus, where my project was selected,” Mannat shares.

This was the inaugural year of the Stockholm Junior Water Prize India (SJWP India), an initiative by the Sustainability Venture Studio (SVS) at Indian Institute of Technology, Madras. It was organised in collaboration with the SIWI - Stockholm International Water Institute (SIWI) and sponsored by AquaMAP Center for Water Management and Policy, IIT Madras, to empower young innovators to tackle critical water challenges.

[caption id="attachment_39298" align="aligncenter" width="395"] Mannat Kaur with IIT-M Prof. Indumathi M. Nambi in Stockholm[/caption]

Calling her victory at the national championship a significant personal achievement, Mannat who had dedicated the past four years to this project said, “Receiving recognition at the national level in a competition focused on the water domain is truly rewarding. This recognition has also strengthened my determination to continue contributing to solutions that can have a positive impact on both my country and the world.”

Earlier this year, the youngster had participated in the Genius Olympiad, organised by the US based Rochester Institute of Technology and held at the RIT campus in India where the same project earned her an honourable mention.

The award-winning water project

Mannat’s project is an applied research project which focuses on the development of an indigenous, sustainable, cost effective, decentralized greywater treatment unit which collects, treats, and reuses greywater generated in a household at the source.

“This product driven intervention has two units: Scupper Valve and Bilge Vessel which help households save and fight the water crisis without any major modifications in the current home plumbing system and takes up very little space in the bathroom,” explains Mannat adding, “The preliminary prototype testing demonstrates its effectiveness in collecting and treating greywater to an improved level. The solution also has an image processing component which is able to distinguish effectively between the pre-rinse and post-rinse water from the heavily soapy flows, enabling selective collection of greywaters.

[caption id="attachment_39300" align="aligncenter" width="512"] Mannat Kaur with IIT-M Prof. Indumathi M. Nambi in Stockholm[/caption]

Mannat estimates that a single-family can save around 5,000-6,000 litres of precious potable water per month and can reduce 50% of their water demand if her solution gets implemented. This decentralized approach reduces carbon emissions by 80-85 percent compared to the traditional centralized sewage treatment setups (water pumping and operational energy), offsetting 18,000 tonnes of CO2 emissions annually.

“Additionally, due to lower sewage output, it contributes towards embodied carbon savings linked to the plumbing network infrastructure and construction of sewage treatment plants. This solution, therefore, addresses two main challenges - water scarcity and operational carbon emissions associated with freshwater supply, wastewater treatment and conveyance of treated water,” says the youngster, who has applied for a patent at the Indian Patent Office.

It all started when…

In 2016, during an agitation, Mannat witnessed her home tap run dry as the Munak Canal, which supplies water to Delhi, was breached. Her entire neighbourhood struggled to secure even a single bucket of water. “This incident was a wake-up call, prompting me to explore ways to conserve water,” she says.

[caption id="attachment_39301" align="aligncenter" width="618"] Mannat while showcasing her project during Water Prize national championship at IIT-Madras[/caption]

She began monitoring her family’s water usage and identifying areas of waste, conducting water audits at home. Mannat noticed a significant amount of water going to waste and observed her family collecting greywater in a tub for reuse in flushing. When she inquired why this practice wasn't more widespread, she learned that collecting, treating, and reusing greywater requires major retrofit of the toilet and plumbing piping.

“This is how I started looking and developing practical solutions which can be easily implemented and bridge the gap between theoretical knowledge and practical application,” she says.

Experiences at Stockholm

Apart from soaking in the mesmerizing beauty of the European city of Sweden, Mannat got the opportunity to engage in meaningful discussions with experts. She was selected to participate in a talk show titled 'Bridging Borders and Generations with the Stockholm Junior Water Prize,' sponsored by Xylem, the U.S.-headquartered global water technology provider. Later engaging with experts from the Xylem team at their office and touring their facilities was great experience for the teenager.

Visiting the Indian Embassy and meeting Chargé d'Affaires, Mr Rakesh Tiwari, was a cherished moment too. Additionally, interacting with Taikan Oki, professor at the University of Tokyo and former Assistant Secretary General at the United Nations who won the 2024 Stockholm Water Prize in the senior category, made her overall experience even more enriching.

[caption id="attachment_39315" align="aligncenter" width="546"] Mannat Kaur at Stockholm[/caption]

A visit to the Royal Palace, not as a tourist but as an invitee to the Stockholm Water Prize royal dinner and banquet with the King and Queen of Sweden was a once-in-a-lifetime occasion.

Future plan and good influences

Mannat has a deep passion for computer science, machine learning, and emerging technologies. “The myriad challenges that the world has to confront today, such as climate change and water scarcity have ignited in me the desire to work for environmental conservation,” she says adding, “I would like to make use of my technological knowledge to address the impending challenges our generation will inevitably face.”

As a Steve Jobs fan, the youngster believes in proactive resolution rather than passive observation. “I want to impact the world as Steve Jobs had, using technology to change the way we live life. Just as he made personal computing accessible through Macintosh, the first widely sold personal computer (PC), my dream is to make environmental sustainability the easier choice,” she remarks.

[caption id="attachment_39303" align="aligncenter" width="725"] Princess Victoria of Sweden with participants of the Junior Water Prize including Mannat Kaur at Stockholm[/caption]

Mannat lives in a close-knit family of five which consists of her grandfather, her parents and a younger brother who is in grade 10. Considering herself fortunate enough to have spent some time with her late great-grandmother during the formative years of her life, the youngster mentions “I have inherited my creativity from my architect father and analytical thinking from my mathematician mother, a blend of both has shaped my approach to both life and problem-solving.”

To the stars: Arushi Nath’s planetary defense algorithm won her the Canada-Wide Science Fair twice in a row

At the 2023 Canada-Wide Science Fair awards gala in Edmonton, nearly 900 attendees celebrated the achievements of Canadian students. Among them, fourteen-year-old Arushi Nath, the founder of MonitorMyPlanet, became the first back-to-back best project award winner since 1989-1990, claiming the prize in 2022 and then again 2023. Her project on planetary defense, focusing on detecting unknown asteroids using open data, mathematics, and Python – her algorithm did actually manage to locate three unknown asteroids. Arushi already has a long list of achievements to her name - she came in second at the European Union Contest for Young Scientists in 2023, the winner of the 2023 Young Astronomer Award from the Royal Astronomical Society of Canada. In 2020, at the age of 11, she won the NASA SpaceAppsGlobal Challenge and in 2017, was the Canada SpaceApps Winner when she was eight years old! A young genius For as long as Arushi can remember, she was fascinated by the night sky, and the many mysteries it represented. "I remember using binoculars to pick out planets and trying to identify patterns. And I still remember seeing the rings of Saturn for the first time, when I was nine" says Arushi, in an interview

says Arushi, in an interview with Global Indian. Academically, she had long since surpassed her school work, and wanted to spend her time taking deep dives into the subjects she loved most – math, coding and astronomy. Her parents – her father is an environmentalist and her mother a writer – supported their daughter fully and when Arushi was six, her dad drove her to her first ever hackathon.

[caption id="attachment_34734" align="aligncenter" width="485"] Arushi Nath, winner of the Best Project award at the Canada-Wide Science Fair 2023[/caption]

The hackathon veteran

This was 2014 and Arushi was the youngest competitor there, by far. NASA's Curiosity rover had just landed on Mars and Arushi was "so fascinated by the idea of being able to land and control something on a whole other planet," she smiles. So, at the hackathon, she and her team made a little robot that could identify obstacles and avoid them. Very complex work for a six-year-old - "We created the physical structure, then coded it," Arushi explains. The robot's ultrasonic sensor could detect obstacles and avoid them. And all this was possible because Arushi had already familiarised herself with Arduino - an open-source electronic prototyping platform that allows users to create interactive electronic objects.

As far as Arushi was concerned, doing projects was the best way to learn. She also wanted to bring her scientific acumen together with the things she cared about. So, in 2018, when she and her friends attended the School Strike for Climate started by Swedish Climate activist Greta Thunberg, Arushi wanted to do more “than raise slogans or wait for others to act,” she said.

S.N.A.C.K.

This led to her designing ‘Schools and NASA Aiding Climate Action by Kids’, which comes with the catchy abbreviation, ‘S.N.A.C.K.’. The project uses satellite imagery to calculate tree densities of schools in Toronto, than ranks and maps them. She also designed a pollution sensor to measure levels in parks and schools across the city, using Arduino, the open source electronics platform that lets users create interactive models. “I wanted school children to come up with local solutions to global challenges,” she says.

Her efforts resulted in her being named the NASA SpaceApps Global Nominee – she had already won the Space Apps Challenge in 2014 and again in 2018. In fact, by the age of 10, she had been at a jaw-dropping 29 hackathons. This was a special win, though, she says, of S.N.A.C.K, as it was her first solo attempt. ” I had to do all the work myself, from thinking of the idea, making it, coding and presenting it to the judges in 40 hours.”

The dragonfly drone

As far as Arushi was concerned, doing projects was the best way to learn. During the Covid-19, she began work on her first major endeavour – building a drone – quite a feat for the young scientist, who was only 10 years old at the time. The idea for the directional dragonfly drone was born during the COVID-19 lockdown. Disturbed by the news of locusts devastating crops in Asia and Africa, Arushi saw an opportunity to make a difference. "These locusts often travel in large swarms, are very fast, and can change direction unpredictably," the Global Indian explained, underlining the urgency of the problem.

Arushi's solution was to use drones for locust control, "as they can fly, follow the locusts, and monitor their behavior," she explains. She also wanted to biomimic nature, choosing the dragonfly because it is by far the most efficient hunter, with a 95 percent success rate in catching prey (in comparison, the success rate of lions is 25 percent and sharks have a 50 percent chance of success). "I made a protoype using a soda can, a motor and a distance sensor I created on Arduino," Arushi says. When she returned from the Ellehacks hackathon, she refined her model, using lego pieces to create a drone "I programmed it to identify all red objects as locusts," she said, describing the functionality of her creation.

The planetary defense system

Given her involvement with the Royal Astronomical Society of Canada, her prowess with Python and her love for Maths, Arushi was casting around for a way to bring all her passions together. That's how she the idea for planetary defense against unknown asteroids was born. She had learned about robotic telescopes through the RASC and utilised images from these devices – “I took images from robotic telescopes in Canada, Spain, the US, and Australia to get full sky coverage," Arushi explains. She had to sift through these to pinpoint the unknown asteroids, using the Gaia Star Catalogue for information on star positions, and the NASA Horizon dataset, for predictions on the locations of known asteroids. Then, using her coding and math skills, she developed an algorithm to filter out known entities - “I created custom masks to remove all these objects, leaving me with the unknown objects," she explains.

She couldn’t always go it alone, though, often turning to online forums for help. "When I got some errors, I would try for days, even weeks, on my own to find the answer, but if not, I would reach out to specific forums," she says. She also reached out to experts, including Christina Thomas, the lead investigator on NASA’s DART mission. “"I sent her a message, told her about my current project, and asked if I could have a Zoom meeting to talk to her about her project and how it could relate to mine," Arushi smiles. Thomas responded and the two did get on that Zoom meeting. "I actually asked her for pointers on my project and what I could do," she adds.

Finding acclaim

“The whole thing took about ten months to complete,” Arushi says, Her goals changed along the way, so much so that her first goal and the end result were very different.” Finally, her findings were sent to the Minor Planet Center database. Then came waiting for a response. “A couple of weeks later, I got an email and three of the asteroids had my name next to them,” Arushi smiles. She submitted her project to the Toronto Science Fair and won gold, qualifying for the prestigious Canada-Wide Science Fair, where she also went on to win. “I was watching the results with my family and wasn’t expecting my name to pop up again but it did,” she says.

Now, Arushi is continuing work on her planetary defense project. Now that the DART Mission has successfully entered the Didymos (asteroid) system, she wants to measure the changes of the system during this impact. "I began studying the Didymos binary system for a copule of months before the DART impact," she says, "To fully understand how it has been affected."
