Purpose. To develop a prototype of a digital twin for a robotic device capable of reproducing an object's motion in real time with high accuracy.
Methodology. To achieve the objective, the following methods were employed: integration of ESP8266 NodeMCU v3 and Arduino Uno R4 Wi-Fi microcontrollers with an MPU6050 sensor, firmware development using the C++ programming language in the Arduino IDE environment, creation of server-side software using PHP scripts and a MySQL database, and the development of an interactive data visualization system in Unity. Additionally, methods for data filtering and calibration were applied to ensure accuracy.
Findings. A digital twin prototype was developed, which accurately reproduces the movements of a physical object based on data from MPU6050 sensors. The system ensures reliable data collection and transmission from the microcontroller to the server without significant losses or distortions. The data is successfully stored in the MySQL database and is available for further analysis and visualization via interactive 3D models in Unity. Implemented mechanisms for data integrity verification and connection stability provide high reliability of the system over extended periods.
Originality. A novel approach to developing a digital twin has been proposed, integrating ESP8266 and Arduino Uno R4 Wi-Fi microcontrollers with an MPU6050 sensor for data collection and processing, employing real-time filtering and calibration algorithms to enhance data accuracy.
Practical value. The developed prototype of the digital twin for a robotic device expands the possibilities for studying and researching digital twin technologies in robotics.
