It is morning in Maddur, a little village nestled in the valley of the lush Tiruttani hills in Tamil Nadu. I make my way past the railway crossing that looks straight out of an R.K. Narayan story and climb into a rickshaw. It takes me past houses with decorative pillars and thinnais(porches) of old-fashioned houses. As the auto sputters down, I hear the rattle of power looms — the main occupation in Maddur is weaving.

Maddur, of late, has earned a new distinction. The students of Buchireddy Palli Government School have been winning accolades for their clever innovations aimed at saving lives and improving the lives of people with disability. Maddur has few streetlights, and many pedestrians fall prey to road accidents. So Class X students S. Parthiban and V.M. Akashwaran came up with ‘e-slippers’.

The footwear operates on the principle of piezo-electricity and has LED strips that light up when the user walks. Rechargeable lithium-ion batteries, which charge devices like mobile phones, are connected to the slippers.

The duo has also come up with a multi-purpose walking stick with sensors that can detect hazards such as fires or floods.

The Buchireddy Palli Government School is an austere, three-storied building that houses both English and Tamil medium departments from classes VI to XII. When I get there just before lunch break, I spot some bright-eyed children sneaking out of their classrooms. Science teacher R. Dharmalingam, has nothing but appreciation for his students. “They are self-driven, curious and never afraid to ask questions,” he says.

“Most of their projects are self-funded, but the headmaster has also helped. I have sat with them after school hours to encourage them.” The school’s involvement is obvious. Dharmalingam accompanied Akashwaran and Parthiban when they showcased their work at the Southern India Science and Technology Fair in Bengaluru.

Out of the box

At Akashwaran’s house, we are greeted with effusive hospitality. Akashwaran and his friend Gunasekaran, still in their uniforms, are poring over a cardboard model. I ask them what they are working on. “This is a gliding platform meant for people with disability or the elderly so that they can cross railway platforms without having to use the overbridge,” Akashwaran tells me. The two then demonstrate the working model.

Akash thought of this when I complained about the climb at the station. Since then he’s been trying to figure out a workable solution,” beams his mother Vatsala.

“It used to be based on hydraulic motion but I changed it to a motor-based system. The platform will move forward when the switch is pressed. IR sensors will detect approaching trains and the platform will then retreat,” Gunasekaran explains. They have even thought about warning systems — a buzzer sound to alert the blind and a flashing red light for the deaf.

M.N. Haripratap is in Class IX in the same school. He has designed a bridge model where the structure opens up during high tide to allow ships to pass and then folds back again. It won him a district-level prize from the Chief Education Officer of Thiruvallur district.

The students’ love for science and innovation is apparent. “Akash took part in a science exhibition at Sri Krishna Polytechnic and was fascinated by what he saw,” says Vatsala. Interested in electronics, programming and robotics, he recently received a special prize for excellence in science from Anna University, Chennai, during its tech fest, ‘Kurukshetra’. He was also awarded a token of appreciation by former ISRO director Mylswamy Annadurai.

“I want to be a scientist,” says Akash. “Abdul Kalam has always been a role model for me.” I ask him what’s next on the agenda. His small, serious face lights up as he talks of solar-powered cycles, ambulance-sensitive speed-breakers, and earthquake-sensing fences.

Whatever the students of this special school do next, I know they will put Maddur on the map with their thoughtful, people-focused innovations.
