Two filed patents, a smart blind stick in daily use, and an E-Rickshaw that turned a wheelchair user into an earning member of his family. Every build starts with a real person’s problem.
Got a problem worth solving? Bring me the constraint, the frustration, the thing nobody has fixed yet. I’ll bring the prototype.

Millions of physically challenged Indians have no realistic access to physiotherapy. HOPE is a wearable brace that moves the user’s limbs through guided contraction and relaxation, and adjusts to fit individual limb shapes. Early trials showed it could assist motor function but lacked feedback and safety margins, so we added a force sensor to guard against excessive torque and a companion app that turns each session into trackable data. It carried me onto Team India at the Regeneron ISEF in Engineering Mechanics.
We took our first prototype to a blind school and let the students use it, then asked them what actually scared them out on the street. Their answers reshaped the design. The final stick uses LIDAR obstacle detection, GPS navigation, and image processing to warn the user before contact rather than at it. We won 1st position in Innovation Project and Research at the FIRST LEGO League North India Championship, then built finished sticks and handed them to the students. They still carry them.
I designed and built an E-Rickshaw a wheelchair user can drive themselves, without transferring out of the chair. The idea came from a month in Ladakh, where depending on someone else for every trip into town made me think about people who live with that dependence permanently. The vehicle is now in service with an NGO partner, and the driver it was built for earns from it. He went from being supported by his family to supporting it.
Sonam Wangchuk holds over 400 patents — one of only five Indians with that many — and inspired the lead character in 3 Idiots.He invited me to Ladakh for a month to automate systems at the new
SECMOL building.
I built three things there: insulating curtains that open at sunrise and close at sunset, a passive-heating indicator that tells students exactly when to open their windows, and a greenhouse ventilation controller that protects plants above 26°C.
