Abstract

The development of technology, particularly in the field of robotics, is increasingly influencing various aspects of life, including the organization of robot contests which are attracting more participants. The Indonesian Robot Contest (KRI) and the ABU Robocon Indonesia Robot Contest (KRAI) are competitions involving broad participation from across the Asia Pacific. Robots in these competitions are controlled using instructions from operators, where the use of wireless joysticks has become very common to enhance control efficiency. However, in practice, issues such as signal connection loss often occur, especially when using PlayStation 2 joysticks with limited signal range. This study aims to develop a more stable remote control system using an ATmega 2560 microcontroller and an ESP32 to provide Bluetooth signals. The research method used is experimental, including the stages of analysis, design, implementation, and evaluation. The results show that the control system with an ESP-based PS4 joystick can increase the control range up to 15 meters with more stable connectivity compared to the previous system. Testing also indicates that precise IP address assignment can prevent signal interference from other devices, making this system effective for use in robotics competitions

Abstract

The need for an efficient and reliable weather monitoring system in areas with limited communication infrastructure has led to the development of an Internet of Things (IoT)-based solution utilizing LoRa (Long Range) technology. This study presents the design and implementation of a local-area weather monitoring system using the STM32F103C8T6 microcontroller and the LoRa RA-02 communication module. The system monitors environmental parameters such as temperature, humidity, wind speed, and air pressure using various sensors including DHT-21, BMP280, A3114, and INA219. Sensor data is collected by the transmitter node and sent via LoRa to a receiver node equipped with an ESP32 microcontroller. The receiver processes the data and sends it to the Blynk IoT platform and Google Sheets for visualization and storage. Experimental results show reliable transmission over distances up to 530 meters in dense environments and 2 kilometers in open areas. The system demonstrated low power consumption, making it suitable for solar-powered applications. The proposed solution is practical, flexible, and cost-effective, providing valuable support for weather-dependent decision-making in remote locations..
