Abstract:This paper studies a defense approach against one or more swarms of adversarial agents. In our earlier work, we employed a closed formation (“StringNet”) of defending agents (defenders) around a swarm of adversarial agents (attackers) to confine their motion within given bounds, and guide them to a safe area. The adversarial agents were assumed to remain close enough to each other, i.e., within a prescribed connectivity region. To handle situations when the attackers no longer stay within such a connectivity r… Show more
“…Varava et al (2017); Song et al (2021) developed a "herding by caging" solution, based on geometric considerations and motion planning techniques to arrange the herder agents around the flock. A similar formation was presented in Chipade and Panagou (2019), and further developed in Chipade et al (2021), to let herders identify clusters of flocking adversarial agents, dynamically encircle and drive them to a safe zone. Recently, Sebastián and Montijano (2021) developed analytical and numerical control design procedures to compute suitable herding actions to herd evading agents to a desired position, even when the nonlinearities in the evaders' dynamics yield implicit equations.…”

“…A herder's action is based on the global knowledge of the environment and of the positions of all other agents. With respect to other solutions in the literature (Lien et al 2004;Pierson and Schwager 2018;Chipade et al 2021;Song et al 2021), our approach does not involve the use of ad hoc formation control strategies to force the herders surround the herd, but we rather enforce cooperation between herders by dynamically dividing the plane among them by means of simple yet effective and robust rules that can be easily implemented in real robots.…”
We propose a simple yet effective set of local control rules to make a small group of “herder agents” collect and contain in a desired region a large ensemble of non-cooperative, non-flocking stochastic “target agents” in the plane. We investigate the robustness of the proposed strategies to variations of the number of target agents and the strength of the repulsive force they feel when in proximity of the herders. The effectiveness of the proposed approach is confirmed in both simulations in ROS and experiments on real robots.

“…The solution involves distributing image classification tasks among a group of UAVs, enabling quick image recognition and faster decision-making. [38] introduces and verifies a defensive approach known as "Multi-Swarm StringNet Herding" developed to confront adversarial swarms with a group of defenders. The methodology develops and validates a decentralized version of the Mixed-Integer Quadratically Constrained Program to effectively allocate defenders to identified attacker swarms.…”
The integration of artificial intelligence (AI) and swarm robotics has brought about significant advancements. Swarm robotics is based on decentralized control and self-organization, taking inspiration from natural swarms. It involves employing a large number of uncomplicated robots to collaboratively complete intricate tasks. The algorithms underpinning swarm robotics, which is artificial intelligence, vary depending on the specific role of AI - such as error detection, navigation, coordination, and optimization - and according to the tasks that these robots aim to undertake. In this systematic review, we aim to explore algorithms based on artificial intelligence in swarm robots and the advantages of applying them in the real world. In this systematic review, 74 scientific papers published between the years 2020 to 2024 were examined, but 53 of them were included after applying our methodology to them. The review investigated the common role of AI in swarm robotics, the most commonly used AI algorithms, and the percentage of the research that was conducted and tested in the real world. In conclusion, we discovered that there is a need for research that develops fault detection and coordination strategies, as well as a need for real-world testing.
“…The shepherding model consists of two parts: shepherd agents and herd agents. One or more shepherd agents escort non-cooperative herd agents to the goal area [25], or the defense swarm is treated as multiple shepherd agents, which "escort" attackers to the safety area [26]. However, this problem differs from the escort model in that the HVU has a preset goal rather than being driven by the escort process dynamically.…”
With the development of swarm intelligence and low-cost unmanned systems, the offence and defense of a swarm have become essential issues in defense and security technologies. A swarm of drones can be used to attack some high-value units (HVUs), such as bases or fuel tanks. Moreover, some moving HVUs such as cargo ships are also greatly threatened when attacked by a swarm of unmanned surface vehicles. A promising approach to protect a HVU from the attack of an aggressive swarm is to use another low-cost swarm. However, escorting a HVU with a swarm is challenging since defenders must respond to attacks and carry out escorts in a noncentralized manner. It is difficult to balance the above tasks well using the unilateral escort strategy adopted by defenders in previous studies. Therefore, this paper proposes a bilateral cooperative strategy for the swarm escort problem under the attack of aggressive swarms. In this bilateral cooperative strategy, the HVU adaptively select different evasion strategies by inferring the threat level according to the spatial distributions of the defenders and attackers. Meanwhile, the defenders of the swarm take a noncentralized escort algorithm by moving around the HVU in a dual-layer formation. Within each layer, the defenders cluster into several uniformly distributed subswarms to counteract the attackers. Numerical simulations are conducted using different aggressive swarm models to demonstrate the effectiveness of the proposed bilateral cooperative strategy.
