Braigo (Brai-lle +Le-go) is a Braille printer design. Braigo version 1.0 uses a Lego Mindstorms EV3 kit, which includes a microprocessor with assorted components such as electric motors, sensors and actuators. Braigo v1.0 was designed by 13-year-old Shubham Banerjee in January 2014, as an entry in 7th grade school science fair project. The model was based on the PLOTT3R, a bonus model released with the EV3 kit and originally designed by Ralph Hempel. The cost was said to be about 350 USD or 250 Euros for the Lego Mindstorms EV3 kit and some extra commonly used hardware whereas a conventional Braille printer retails starting from about US$1,900.
