ABSTRACT
Logos, labels, or just plain art, spray painted on walls, can be used to attract people. This makes them very useful especially when there are people who might want to endorse a product or brand name to attract potential customers. Long exposure to Spray Paint fumes can result pneumonitis, cardiac problems, and chronic bronchial asthma that can lead to emphysema. This study was conducted in order to address those health problems with the use of robots. Robots are impervious to the hazardous effects caused by long-term exposure to spray paint fumes and do not tire of repetitive and continuous work. The Lego Mindstorms NXT robotics kit was used during the development of the robot to operate. The NXT brick along with three servo motors were taken from the kit and then integrated within a wooden structure together with a spray paint can. The NXT brick and two of the servo motors were attached to a wall and then connected to the third servo motor, which is affixed to a wooden structure with a spray paint can, via a pair of timing belts. The robot was programmed using the NXT -G programming language that enabled it to spray paint different designs or figures, such as square and a triangle.
