Writing Machine for Blind People

Abstract

Examination are conducted through online processes. The job recruitment process and degree entrance examination like JEE, GATE, NEET, etc. will be conducted via online center through a third-party company. So, this chapter, per the authors, proposes a system that uses transducer for getting input as a voice. Later, the voice is converted into text then linked with the benbox software and the chosen file is taken as a command for the writing machine. Arduino Uno R3 is connected with stepper motor driver, metal gear servo, expansion board A4988 driver for writing. The machine uses a gantry to move the writing tip along the X and Y axes. The flexible-nib pen is mounted on a servo motor, which rotates the tip onto the third axis. This machine provides comfortability for blind people to write their exam by using voice command.
