12-year-old Shubham Banerjee received a flyer on his doorstep, asking for donations for the visually impaired. This led him to thinking about the hardships visually impaired people face on a regular basis. He learned through a Google search that the average Braille printer costs $2,000. So, Banerjee invented his own Braille printer out of Legos.
“I think I am doing something that can actually help people,” Banerjee said. “I wanted to do something for others, but didn’t know much about Braille."
Called Braigo, the printer took a month and seven failed models for Banerjee to create.
“I didn’t know if it was possible but I wanted to at least give it a try,” he said.
Braigo was created using a set of LEGO MINDSTORMS EV3 set and a modified robot model. It works by using push pins as the print head, which pushes the Braille characters into paper. A controller is used to scroll and choose the right alphabet. Braigo takes five to seven seconds to print out one letter.
“Over 200 million people in the world are blind and 90 percent of them are living in developing countries. And, a lot of people can’t afford the costly machines available in the market. So, can’t we do something about the cost?” Banerjee said.
