ABSTRACT: This study presents a Unity-based digital twin for robot arm monitoring and remote operation. Physical robot joint states were transmitted to Unity for real-time visualization, while operator-defined commands were sent from Unity to the physical robot. The two data flows were integrated through User Datagram Protocol (UDP) communication to establish bidirectional real–virtual interaction. The developed system enabled robot posture synchronization and operator-driven remote operation without autonomous closed-loop control.
