Item Sistem Deteksi Gawang Pada Robot Barelang 7.1(Politeknik Negeri Batam, 2018-06-06) Riandi, Imam Agus; Sugandi, Budi; Prayoga, SenanjungA soccer robot must be able to drive and kick the ball towards the goal in a soccer game. A soccer robot must be equipped with a goal detection system using camera as the main sensor. The majority problem is intensity of light can affect successful introduction of white goal, where the level of light intensity can cause brightness of a color different so it is difficult to detect a color. In this research developed a detection system by using a combination of contour detection and color filtering. The results show success rate of 85.18%, where the system can detect goal in range of distance from 1.5 m to 9 m. System testing is performed on three different positions: left, center, and right. The system created has an average process speed of 27.47 fps (frames per second) which indicates that the value is categorized as normal for an image processing system.Item Robot Drawing Dengan Pergerakan 3 Axis(Politeknik Negeri Batam, 2018-06-06) Amasta, Gusti; Soebhakti, HendawanCurrently the world of robotics began to grow rapidly with the appeared various types of robots. Robot is an option to help human work solve problems such as precision, security, flexibility and repetitive work. In the field of art they are many artists who were drawing using software, which are many conveniences in it. However, to print images into real the one, many artists still use printers which uses ink to print images, so the images do not look like drawn by real humans. To overcome these situation, the author makes a robot to print the images that exist in the software by using a pencil. By using the pencil the image looks more real as made by humans. This system uses the GRBL method or enter the commands from the cnc machine into the microcontroller. The image on the software will be converted into gcode and then read by processing software serialized to arduino for movement in drawing. The movement is used 3 axis, such that 2 stepper motors for x, y axis and 1 servo motor for movement on z axis. The results of the test show that the robot can draw flat shape like square, rectangle, circle, triangle and parallelogram. Robot can also move to a specified position in the software. The speed of drawing 5 two-dimentional figures are 2 minutes 3 seconds.
