Succeeding in uncharted waters

Hydroswarm is commercializing the football-sized autonomous underwater drones Bhattacharyya helped develop. These egg-shaped robots are capable of working alone or in tandem to map the ocean floor, inspect underwater nuclear reactors, search for lost planes and complete virtually any other underwater surveillance task. The startup won $50,000 in last year’s MassChallenge and has captured worldwide attention with its innovative, relatively inexpensive robot design.

Soon thereafter, she was named to Forbes 30 under 30 Class of 2016 for Manufacturing/Industry, an honor that recognizes bright, young change agents. And in her spare time, she co-founded an international non-profit.

Yet according to societal expectations in her native India, not attending a top engineering school should have spelled the end of Bhattacharyya’s career before it even began, she said.

Originally she wanted to be an astrophysicist, but Bhattacharyya followed her mom’s advice and enrolled in engineering instead because it offered better career prospects. Like most small Indian colleges, her alma mater lacked resources that are standard in U.S. universities, she explained, such as well-equipped laboratories and hands-on learning opportunities.

“At the time the only jobs you could get were in IT,” Bhattacharyya said. “It didn’t matter what you studied, the jobs were in IT because there was no culture of hands-on building.”

Knowing she wouldn’t enjoy IT work, Bhattacharyya began applying for other opportunities. She was offered an internship at Fermilab, America's premier particle physics laboratory. She calls it a turning point.

“That was the first moment that I realized what engineering actually is,” she explained. “You don’t just study and memorize books. Engineering is much more hands-on.”

Her passion for engineering fully ignited, Bhattacharyya decided to pursue a master’s in aeronautical and aerospace engineering at The Ohio State University.

“Knowing that it’s a big school, I realized that would really open up the power of connections for me and give me a very new direction in life,” said Bhattacharyya. “Ohio State is very research-oriented, has lots of students, and I found it very appealing and wanted to experience that life.”

Her master’s research with Mechanical and Aerospace Engineering Professor Rama Yedavalli involved using a particle accelerator beam to produce energy from nuclear waste. That process also made the waste less radioactive.

“Looking back, I did a pretty intense master’s project,” she said. “I really enjoyed it. I was working full-time from the lab on the feasibility analysis and beam control.”

Bhattacharyya’s original plan for her doctoral research at MIT was to build the model system she had designed at Ohio State, but she soon realized the regulatory issues involved would be beyond the scope of her project. So instead she started working with Ford Professor of Engineering Harry Asada on a robot designed to look for cracks in a nuclear reactor’s water tanks.

One day, while reading about contraband smuggling, Bhattacharyya realized that their robots could also search ships for contraband hidden in cavities or fake chambers.

Then Malaysia Airlines flight 370 went missing.

She suspected those little robots might be able to do a whole lot more, like locate missing wreckage.

Unlike existing underwater vehicles that are large, expensive and tend to be very mission specific, Hydroswarm’s small drones are relatively cheap. Able to navigate autonomously through water as well as along underwater surfaces, the battery-powered robots can be fitted with various sensors, depending on the desired task.

The company’s innovative robot concept has been covered internationally in outlets such as The Guardian, New Scientist and Smithsonian.

One of the team’s breakthrough advancements is how quickly the robots can communicate with each other, enabling them to be used alone or in groups to cover more territory.

“You can take it and use it for whatever you want,” explained Bhattacharyya. “That makes us able to grow, scale and make many of them faster and for many missions.”

Although she’s excited to earn her PhD soon and work full time as the startup’s CEO and chief scientist, Bhattacharyya hasn’t forgotten the challenges she faced as an undergraduate student. So she co-founded and helps run non-profit Lab-X Foundation together with other young engineers—including fellow Buckeye engineers Ketan Dande (EE MS ’12) and Varun Joshi (EE MS ’12)—to provide hands-on opportunities and global exposure to students in developing countries.

“[Ketan, Varun and I] met at Ohio State and had the same story. We came from small engineering schools. Why couldn’t we have stayed in India and built great stuff? Because nobody would give us the opportunity to do something,” Bhattacharyya said. “I think we are wasting a huge amount of human resources and talent we could put toward something much more innovative. That’s why I started Lab-X.”

Lab-X Foundation aims to create a culture of hands-on learning through programs such as internship opportunities, research demonstrations and workshops, student poster and exhibit sessions, and presentations from diverse speakers.

For future engineers who want to break barriers of their own, Bhattacharyya offers some simple advice: believe in yourself, don’t be afraid to try new things and do something you truly enjoy.

“Don’t say, ‘I’m terrible in math, I can never do engineering.’ I was totally flunking in physics in eleventh grade, so that’s not true,” she said. “Try engineering, don’t be scared of it. Don’t give undue relevance to grades, in the end it’s just a number out there. It’s really what you create with your hands and your mind.”
