Swarm robotics is a field of robotics that focuses on the coordination of multiple robots to work together as a group, similar to how swarms of insects, like ants or bees, operate. These robots communicate and collaborate to accomplish tasks more efficiently than a single robot could do alone. The key principles of swarm robotics include decentralization, scalability, and robustness. This means that each robot operates independently while still contributing to the overall goal, allowing the system to adapt to changes and continue functioning even if some robots fail.
