Color-Coded Light Signals for Swarm Robot Communication

What is it about?

Swarm robotics uses multirobot systems with simple agents and limited capabilities to enhance scalability. Research in this field is limited due to the complexity of control and communication systems. This paper presents minimobile robots that use color-coded light signals for communication, enabling efficient and directional signal transmission. The robots demonstrate various swarming behaviors using this communication technique. The developed robots can be manually controlled or operated autonomously, and their behavior can vary based on speed. Simulations and verification experiments were conducted to evaluate the system's behavior. The robots showed different swarming behaviors using visible light communication, demonstrating the effectiveness of the proposed technique. The color-coded light-based communication system allows for simultaneous transmission of multiple signals using different colors, enabling efficient communication and coordination among robots. However, the technique may face limitations in situations with superimposed light signals. Future research can explore the use of more colors, additional sensors, and more versatile motor encoders for better localization of individual robots. More swarming behaviors can also be explored.
