Abstract:

Wall painting is a repetitive, exhausting and hazardous process which makes it an ideal case for automation. Painting had been automated in automotive industry but not yet for the construction industry. There is a strong need for a mobile robot that can move to paint interior walls of residential buildings. In this paper, the conceptual design of an autonomous wall painting robot is described consisting of an arm that scans the walls vertically and is fitted on a mobile robot base to give the lateral feed motion to cover the painting area. The design objective is to satisfy the criteria of simplicity, low weight, low cost and fast painting time. Ultrasonic sensors are fitted on the arm and the mobile base to adjust the motion limits and maneuver in the room area .A control system is designed to guide the arm motion and plan the mobile base motion
