Abstracts: 2D Plotter plots the outlines of the image given to it on blank paper. A mechanism is designed for moving pen on blank paper in x and y direction. This mechanism contains stepper motors, timing belt, pulley and essential gears. Stepper motor in turn moves timing belts and in turn moves pen on the paper. These stepper motors are controlled using Raspberry Pi. Raspberry pi is a credit card sized computer. It operates on its own Linux based operating system Raspbian. A stepper motor driver circuit is developed and it is interfaced with Raspberry Pi. Image is stored on the SD card of Raspberry Pi and image outlines are determined using image processing. Image processing will be done in c. after the outlines of image is determined, the output image will only contain its edges, coordinates of edges are determined and according to the coordinates of the output image, stepper motor is controlled step by step and thus pen will move pixel to pixel and image will be plotted on blank paper
