We review recent advances in swarm robotics, highlighting human– and animal–swarm interaction, decentralized programming, robustness, field applications, and emerging directions. This chapter reviews recent advances in swarm robotics, focusing on human–swarm and animal–swarm interaction, decentralized programming frameworks, and strategies for robustness. Frameworks such as ROS 2 and Buzz enable scalable programming, while n-version programming, fault detection, and blockchain improve reliability, fault tolerance, and security. Distributed SLAM (or C-SLAM) supports collaborative mapping, and new interfaces use swarms as displays or integrate augmented reality to enhance sensing. The move toward field robotics introduces swarms to unpredictable environments on land, in the air, and on water, presenting new challenges for robustness and autonomy. Future directions include morphological computation, where robot design influences behavior, and Green Robotics, which prioritizes energy harvesting for sustainability.
