Preliminary Study on Real-Time Teleoperation of Underwater Crawling Robots via Cyber Physical System(CPS) and Internet

Abstract

KRISO has developed a smart operational technology applied to underwater robots based on the principle of a cyber-physical system. This technology is designed to enhance operators' ability to accurately perceive underwater situations. It enables them to make informed decisions and effectively control the robots for safe and efficient operations. Situation awareness in underwater operations includes recognizing the robot's motion, changes in the environment, and the ongoing operational context. This paper introduces the preliminary study of real time teleoperation of underwater robots located at a distance from land-based center. The VR operational system is located in the Digital Twin Center building, while the underwater crawling robot is situated in a separate building with a water tank, and they are connected via the internet. To guarantee the seamless and reliable real-time exchange of large volumes of data via internet, the mitigation strategies of network latency and bandwidth should be proposed.
