About the solution
Shubham then did some online research and was shocked to learn that Braille printers cost at least $2,000. He also learned more about Braille, the tactile writing system used by the visually impaired. He said "When I found out the cost of a Braille printer, I was shocked. I just wanted to help the visually impaired. I had a Lego Robotics kit, so I asked, 'Why not just try that?'"
Built out of Lego’s Mindstorms EV3 blocks and little pieces from Home Depot (Braigo stands for Braille and Lego), Braigo Lab's printer turned out to function quite well.
Shubham believes it could solve a decades-long problem that has been holding back so many visually impaired people around the world: the high cost of Braille printers. He wants to develop a desktop Braille printer that costs around $350 and weighs just a few pounds, compared with current models that can weigh more than 20 pounds.
The machine could be used to print Braille reading materials on paper, using raised dots instead of ink, from a personal computer or electronic device. He then founded his own company.
