At just 10, Aaradhya Jain from Noida, Uttar Pradesh, has taken her idea for a smart assistive cane to an international stage, presenting and demonstrating STAMBHA, her smart assistive cane, at the Second World Summit on Sustainable Health and Well-Being at the United Nations Conference Centre in Bangkok. STAMBHA, named after the Hindi word स्तम्भ, meaning “the pillar”, is designed for elderly people and those with visual impairments.
From A Simple Question
The story of STAMBHA begins with a simple but deeply human thought: a walking cane can help someone find their way, but who is watching over the person using it?
“Every walking stick ever built senses the ground. I wanted one that senses the person.”
That reversal is what sets the device apart. Existing smart canes look outward, at the path ahead. STAMBHA does all of that, with a laser that detects obstacles two metres ahead and warns through vibration in the palm, while a camera describes what it is pointed at and reads signs aloud. It then turns much of its attention inward, to the person holding it.
Of the nine sensors built into the cane, two face the world. The remaining seven face the user, reading pulse, blood oxygen, grip and the steadiness of their walk from the hand already resting on the handle.
Built Without An App
STAMBHA is designed as a complete device in its own right. While most smart canes are accessories where the cane collects information and a paired phone does the thinking, everything that keeps a STAMBHA user safe runs on the cane itself.
It requires no app or pairing. It borrows a phone only for an internet signal, the way a laptop uses a hotspot. Removing even that dependency is part of Aaradhya’s next build.
A Cane That Learns
STAMBHA reads balance nine times a second, allowing it to tell an ordinary stumble from a genuine fall. It can notice when a person’s walk has slipped from their own normal and suggest a rest.
The cane also remembers previous walks. After a week, it knows the kerbs and corners that have caught a particular person. Over time, it learns what is normal for them and can identify when that pattern begins to change.
The cane can also be spoken to. Ask it how you are doing, and it answers from a record of your own body and your own walks rather than from a search. As Aaradhya puts it, it is the difference between a cane that knows about the world and one that knows about you.
An Idea With Purpose
Aaradhya has approached assistive technology not simply as a technical challenge, but as a question of dignity and independence. For an elderly person walking alone, or someone navigating an unfamiliar street, a fall or a sudden change in stability can turn an ordinary journey into an emergency.
The idea came from two places. One was the Bollywood film Srikanth, the true story of a visually impaired entrepreneur. The other was closer to home.
“When I was small, my grandparents were always checking on me – was I warm, was I safe. Then they grew old, and nobody was checking on them. I believe a life should be held all the way through. Not just at the beginning,” Aaradhya says.
Built At A Kitchen Table
Aaradhya designed, wired and programmed the cane herself, using off-the-shelf components that plug together without soldering. The prototype costs roughly $100, or about ₹9,500, in parts, against $850 to $1,150 for a commercially available smart cane.
It is built on a thumbnail-sized ESP32-S3 board programmed in MicroPython.
The World Health Organization attributes about 684,000 deaths a year to falls, with four in five occurring in low- and middle-income countries, and about 871,000 to social isolation. Aaradhya’s presentation was made in support of Sustainable Development Goal 3, Good Health and Well-Being.
From London To Bangkok
The recognition in Bangkok marks another significant chapter in Aaradhya’s journey as a young innovator. Before arriving at the United Nations, she had already taken her work to London, where she was recognised for her innovation and technology work at the British Parliament through the Global Child Prodigy Awards.
She also holds an India Book of Records entry as youngest multi-domain STEM achiever.
At just 10, she has therefore presented on two internationally recognised platforms, first in London and now at the United Nations in Bangkok. But the significance of her journey goes beyond the places: at the heart of her work is an attempt to help elderly and visually impaired people move through the world with greater safety and independence.
Beyond The Technology
STAMBHA is a working prototype rather than a commercial product, and it is not a medical device. It makes no diagnostic claim.
Its learning improves with time in real hands, which is exactly what Aaradhya went to Bangkok to find: people who will walk with it and tell her what to build next.
The significance of her work lies not only in what the device does today, but in the question she has chosen to ask: whether technology can be designed around human vulnerability rather than simply around convenience. Her presentation places that idea within a global conversation about inclusive healthcare, accessibility and well-being.
For Aaradhya, the journey is more personal: it is about imagining a world in which a simple cane can become something more than an object held in the hand.
STAMBHA may still have a long journey ahead, but the idea behind it has already travelled far. She is not waiting to grow up to make a difference. She has started now, with a question, an idea and the determination to build an answer.
The Logical Indian’s Perspective
Aaradhya’s STAMBHA highlights how technology can be approached through empathy and lived experience, rather than convenience alone. The project is still a prototype and has no diagnostic claims, but its focus on dignity, independence and accessibility shows how a simple everyday object can be reimagined around the needs of the person using it.
