Abstract:
This prototype primarily addresses the design of an automatic wall painting robot. The system performs the painting process by the use of sensor information and two Arduino boards. The ultrasonic sensors mounted are on the mobile robot in a way so that the first ultrasonic sensor is positioned to give vertical coordinates while the second ultrasonic sensor gives the horizontal coordinate. Both sensor readings are fed to the arduino boards which control the base DC motors and the actuator. The actuator while extending and retracting raises the scissor lift and lowers it, respectively. The spray gun handle is mounted atop the lift, while the air compressor is set on the lower platform, and is turned ON/OFF at the bidding of the arduino board.
