“…Because of the explanation described above, the author wants to develop or add an android application feature as a prototype controller for a robotic garbage collection ship in the water. Currently, robot applications Iota 2021, ISSN 2774-4353, 02, 03 151/168 using Arduino are applied to various objects such as robot boats, arm robots, Cleaning Robots, and Car Robots, and several methods using Artificial intelligence (AI) [13], Deep Learning, and Data Mining [6] are applied in them [1,8,9,22,23,24,25,26,27,46,47]. Moreover, the prototype robot cannot be separated from the wireless devices inside, usually using Bluetooth HC-05, WiFi module ESP32, ESP8266, Node32, and LoRa or LoRaWAN [2,17,18,19,20,21,45]; some research uses propagation analysis [14].…”
