Wall Painting Robot

Abstract

The painting process has many problems which all about manual labor that suffered from workers whom do the job of painting. So an automatic system was created to exchange the manual labor. The wall painting robotis an autonomous robot for painting the interior walls of buildings and backgrounds. Therobot consists of a painting arm with an end effector roller that scansthe walls vertically and a movable chassis is moving horizontally to paint the whole area of the wall. The painting arm has a planar two-links mechanism with two joints. An ultrasonic sensor is attached to the movable chassis and used to maintain a certain distance from the facing wall and to avoid collision with side walls. When settled on adjusted distance from the wall, the controller starts the painting process automatically. Simplicity, relatively low weightand short painting time were considered in our design. This project has shown successfulness of wall painting robot in itsintended tasks
