Abstract

Penelitian ini membahas perancangan robot omnidirectional dengan tiga roda yang dapat dikendalikan secara koordinat dan mampu menghindari halangan. Metode yang diterapkan melibatkan penggunaan odometri untuk melacak pergerakan robot dan konsep potential field untuk memungkinkan robot menghindari rintangan sambil tetap fokus pada tujuannya. Sebagai pusat kendali, digunakan Arduino Due yang didukung oleh rotary encoder dan sensor ultrasonik untuk memantau posisi serta mendeteksi lingkungan sekitar. Selain itu, sensor kompas digital juga diterapkan untuk menjaga arah hadap robot agar tetap sesuai dengan posisi yang telah ditentukan. Hasil penelitian menunjukkan adanya mean absolute error terbesar pada sumbu x tercatat 0,130 m, sumbu y tercatat 0,134 m, dan mean absolute error arah hadap robot sebesar 0,1111 derajat. Penelitian ini memberikan wawasan tentang performa robot omnidirectional dalam mencapai targetnya dan potensi peningkatan pada aspek-aspek tertentu guna meningkatkan akurasi dan presisi pergerakan robot.

Abstract

Ornamental fish are one of several animals that are often in demand by many hobbyists, not infrequently some of them are willing to spend deeper than the aquarium to support the survival of fish for the sake of ornamental fish that are cared for always healthy. A healthy aquarium requires good care to maintain the survival of the fish and aquatic vegetation contained therein. In addition to the importance of regular fish feeding, water pH and water turbidity greatly determine water quality because they also determine chemical processes in water. In this study a control system was designed to provide fish feed automatically and remotely and monitor pH values, turbidity and water temperature in the aquarium. This tool is operated via Internet- based IoT, so it can monitor water quality and feed automatically via WhatsApp and Blynk. In this case WhatsApp and Blynk can monitor water quality and fish feeding remotely and remotely real-time. The data obtained can be accessed using the whatsapp and blynk applications. The pH 4502c sensor has an accuracy rate of 97.05%, the DS18B20 temperature sensor has an accuracy of 97.37%, and the SEN0189 turbidity sensor has an accuracy of 97.12%. The average response speed for sending replies to orders on WhatsApp is 4 seconds.
