Special Issue Information

Dear Colleagues,

In recent years, the field of unmanned systems has witnessed remarkable advancements, leading to the emergence of intelligent unmanned systems capable of perceiving, making decisions, and autonomously controlling their actions. These systems, often referred to as autonomous or intelligent unmanned systems, have revolutionized various industries, including transportation, agriculture, surveillance, and exploration. They have the potential to enhance efficiency, reduce human error, and perform tasks that are too dangerous or tedious for humans. Unmanned Aerial Vehicles (UAVs), commonly known as drones, have experienced significant advancements in recent years thanks to the integration of intelligent capabilities. These intelligent unmanned systems have revolutionized the field of UAVs, enabling a wide range of applications across various industries, such as aerial photography and videography, precision agriculture, search and rescue operations, infrastructure inspection, environmental monitoring, and so on.

At the core of these intelligent unmanned systems lie three fundamental components: perception, decision making, and control. Perception involves the ability to gather and interpret information from the environment using various sensors such as cameras, lidar, radar, and other specialized sensors. This information is then processed to create a representation of the system's surroundings, enabling it to understand and interact with the world. Once the perception phase is complete, the intelligent unmanned system moves on to the decision-making stage. These decisions can range from simple tasks, such as obstacle avoidance, to complex actions, such as route planning, target identification, or collaborative decision making in a multi-agent environment. Finally, the control component comes into play, where the intelligent unmanned system executes the decisions made during the decision-making phase.

The integration of perception, decision making, and control in intelligent unmanned systems is a highly interdisciplinary field, drawing upon expertise from various domains such as artificial intelligence, robotics, computer vision, machine learning, and control theory. Researchers and engineers in this field strive to develop algorithms, architectures, and techniques that enable unmanned systems to operate autonomously, adapt to dynamic environments, and interact safely and effectively with humans and other agents. The challenges in developing perception, decision-making, and control capabilities for intelligent unmanned systems are numerous. These include the need for robust and accurate perception algorithms, efficient and scalable decision-making frameworks, real-time control strategies, and the ability to handle uncertainty and unexpected situations.

In conclusion, the field of perception, decision making, and control of intelligent unmanned systems holds immense potential for transforming various industries and enabling a wide range of applications. As technology continues to advance, the development of robust and reliable algorithms and systems will pave the way for the deployment of intelligent unmanned systems that can operate autonomously, adapt to changing environments, and collaborate with humans and other agents effectively.

As technology continues to advance, we can expect further innovations in areas such as swarm intelligence, collaborative decision making, and enhanced autonomy, opening up new possibilities for UAVs in various industries and domains.

In this work, an innovative perception-guided approach is proposed for landing zone detection and realization of Unmanned Aerial Vehicles (UAVs) operating in unstructured environments ridden with obstacles. To accommodate secure landing, two well-established tools, namely fuzzy systems and visual Simultaneous Localization and Mapping (vSLAM), are implemented into the landing pipeline. Firstly, colored images and point clouds acquired by a visual sensory device are processed to serve as characterizing maps that acquire information about flatness, steepness, inclination, and depth variation. By leveraging these images, a novel fuzzy map infers the areas for risk-free landing on which the UAV can safely land. Subsequently, the vSLAM system is employed to estimate the platform’s pose and an additional set of point clouds. The vSLAM point clouds presented in the corresponding keyframe are projected back onto the image plane on which a threshold fuzzy landing score map is applied. In other words, this binary image serves as a mask for the re-projected vSLAM world points to identify the best subset for landing. Once these image points are identified, their corresponding world points are located, and among them, the center of the cluster with the largest area is chosen as the point to land. Depending on the UAV’s size, four synthesis points are added to the vSLAM point cloud to execute the image-based visual servoing landing using image moment features. The effectiveness of the landing package is assessed through the ROS Gazebo simulation environment, where comparisons are made with a state-of-the-art landing site detection method. Full article

In extensive outdoor collaborative exploration tasks, multiple robots require efficient path planning methods to ensure rapid and comprehensive map construction. However, current collaborative mapping algorithms often integrate poorly with path planning, especially under limited communication conditions. Such conditions can complicate data exchange, leading to inefficiencies and missed areas in real-world environments. This paper introduces a path planning approach specifically designed for distributed collaborative mapping tasks, aimed at enhancing map completeness, mapping efficiency, and communication robustness under communication constraints. We frame the entire task as a k-Chinese Postman Problem (k-CPP) and optimize it using a genetic algorithm (GA). This method fully leverages topology maps to efficiently plan subpaths for multiple robots, ensuring thorough coverage of the mapping area without the need for prior navigation maps. Additionally, we incorporate communication constraints into our path planning to ensure stable data exchange among robots in environments with only short-range communication capabilities. Field experiment results highlight the superior performance of our method in terms of stability, efficiency, and robust inter-robot communication. Full article

With the rapid advancement of UAV technology, the utilization of multi-UAV cooperative operations has become increasingly prevalent in various domains, including military and civilian applications. However, achieving efficient coordinated rounding-up of multiple UAVs remains a challenging problem. This paper addresses the issue of collaborative drone hunting by proposing a decision-making control model based on deep reinforcement learning. Additionally, a shared experience data pool is established to facilitate communication between drones. Each drone possesses independent decision-making and control capabilities while also considering the presence of other drones in the environment to collaboratively accomplish obstacle avoidance and rounding-up tasks. Furthermore, we redefine and design the reward function of reinforcement learning to achieve precise control of drone swarms in diverse environments. Simulation experiments demonstrate the feasibility of the proposed method, showcasing its successful completion of obstacle avoidance, tracking, and rounding-up tasks in an obstacle environment.

Multi-unmanned systems have demonstrated significant applications across various fields under complex or extreme operating environments. In order to make such systems highly efficient and reliable, cooperative decision-making methods have been utilized as a critical technology for successful future applications. However, current multi-agent decision-making algorithms pose many challenges, including difficulties understanding human decision processes, poor time efficiency, and reduced interpretability. Thus, a real-time online collaborative decision-making model simulating human cognition is presented in this paper to solve those problems under unknown, complex, and dynamic environments. The provided model based on the Soar cognitive architecture aims to establish domain knowledge and simulate the process of human cooperation and adversarial cognition, fostering an understanding of the environment and tasks to generate real-time adversarial decisions for multi-unmanned systems. This paper devised intricate forest environments to evaluate the collaborative capabilities of agents and their proficiency in implementing various tactical strategies while assessing the effectiveness, reliability, and real-time action of the proposed model. The results reveal significant advantages for the agents in adversarial experiments, demonstrating strong capabilities in understanding the environment and collaborating effectively. Additionally, decision-making occurs in milliseconds, with time consumption decreasing as experience accumulates, mirroring the growth pattern of human decision-making. Full article

To realize unmanned aerial vehicle (UAV) situation assessment, a Bayesian network (BN) for situation assessment is established. Aimed at the problem that the parameters of the BN are difficult to obtain, an improved whale optimization algorithm based on prior parameter intervals (IWOA-PPI) for parameter learning is proposed. Firstly, according to the dependencies between the situation and its related factors, the structure of the BN is established. Secondly, in order to fully mine the prior knowledge of parameters, the parameter constraints are transformed into parameter prior intervals using Monte Carlo sampling and interval transformation formulas. Thirdly, a variable encircling factor and a nonlinear convergence factor are proposed. The former and the latter enhance the local and global search capabilities of the whale optimization algorithm (WOA), respectively. Finally, a simulated annealing strategy incorporating Levy flight is introduced to enable the WOA to jump out of the local optimum. In the experiment for the standard BNs, five parameter-learning algorithms are applied, and the results prove that the IWOA-PPI is not only effective but also the most accurate. In the experiment for the situation BN, the situations of the assumed mission scenario are evaluated, and the results show that the situation assessment method proposed in this article is correct and feasible.
