Home / Computers/technology / Gadgets / Video: Diy Homework Machine From A Pc Dvd Writer


Learn how to make a homework writing machine for students using a Arduino nano microcontroller. For the X and Y axes you will use two stepper motors and rails from DVD/CD drivers, and for the Z axis you will use a small servo motor that moves the pen up and down.

The machine uses a gantry to move the writing tip along the X and Y axes. The flexible-nib calligraphy pen is mounted on a sprocket which rotates the tip onto the writing surface, taking care of the third axis. You can use the machine to do pretty much whatever you can dream up from drawing fancy artwork to extensive calligraphy on letters.

Combined with personal handwriting software, you could even use the plotter to write a letter in your own handwriting without all of the efforts.

You will need the following components before you can make your very own robot-assistant:

  1. 2x Old PC DVD Writer
  2. Arduino nano
  3. Servo motor
  4. L293D IC
  5. Prototyping Board
