Abstract
Interior wall painting is a common work in construction which consumes a lot of time and human effort. By replacing human manual operation, robotic painting was introduced to improve the accuracy, efficiency and to reduce the cost. In this paper, we introduce an autonomous wall painting robot which can paint the interior walls of a room, using paint sprayer with the help of a cascade lift mechanism. This cascade lift mechanism assists the paint sprayer to reach the required heights. The mecanum wheels with dc motors that are attached to the base of the robot, helps in easy movement of the robot, to move in all six directions with 2 DOF (degrees of freedom). The robot uses ultrasonic sensors to detect the distance and adjust to the walls, and to check whether the sprayer reached the top of the wall. The master controller controls the ultrasonic sensors, mecanum wheels, and all other parts of the robot. The overall system runs on AC power supply.
