Demonstration of Real-Time Localization and Control for Autonomous Robots via Optical Camera Communication

Optical Camera Communication (OCC) uses light sources and Complementary Metal-Oxide-Semiconductor (CMOS) cameras for visible light communication. In this study, we propose a real-time system for self-localization and control in autonomous robots using OCC. This system enables precise localization and low-latency control without LiDAR, reducing costs and maintenance demands. Experimental results demonstrate localization accuracy comparable to advanced Simultaneous Localization and Mapping (SLAM) while ensuring responsive control with minimal latency. Optimizing LED placements further enhances localization accuracy. This method offers a cost-effective and reliable approach for autonomous robots navigation in various environments.
