AGWallP — Automatic guided wall painting system

Abstract

This paper presents the development of prototype of Automatic Wall Painting Machine guided by wall dimensions and paint colour being sent from user through a camera embedded Raspberry Pi 2 module. The Raspberry Pi Module captures the wall image and calculates the dimensions using Image Processing tools and remotely forwards the dimensions to the base painter system using bluetooth transmission. The Mechanical structure consists of a 2-D plotter with the painting joint attached to a DC operated DCV (Directional Control Valve) spray paint that moves from a point to another line by line. The plotter runs with two Nema 17 stepper motors and contains a STM32 as the slave controller, receiving the dimensions via bluetooth module connected to it. The overall system is run by a dual shaft Nema 23 Stepper motor.
