Advancements in multi-agent systems (MAS) have enabled swarm-based systems to perform decentralized decision-making and autonomous tasks. However, optimizing their performance while ensuring transparency and interpretability remains a challenge. This paper introduces a framework that combines Bayesian optimization with Explainable Artificial Intelligence (XAI) techniques to enhance both the efficiency and transparency of MAS swarms. The Bayesian optimization framework fine-tunes agent parameters to improve swarm metrics such as energy efficiency, task completion time, and coordination success. The experimental results show significant improvements: a 25% increase in the coordination success rate, a 15% increase in energy efficiency, and a 20 % reduction in task completion time. XAI techniques, including SHAP values, provide interpretable explanations for optimization decisions, improving user trust and understanding. This study demonstrates the efficacy of integrating Bayesian optimization with XAI to create transparent, efficient, and reliable MAS swarms. Future work should address scalability and implications in dynamic environments. © 2025 IEEE.

The dynamics of a quadcopter unmanned aerial vehicle (UAV) and proportional integral derivative (PID) control based on disturbance rejection are mathematically modelled in this work. The model presented is a nonlinear in nature and modelled with respect to the two fundamental frames of reference and physical mathematical laws. The objective is to create the most accurate replica of the vehicle. The created model is utilized to develop a PID controller method that will precisely and steadily operate the quadrotor system. The development of a controller is to obtain stability in the quadcopter system. First, the nonlinear and couple model quadcopter were established, and control described the principles of the ability of decoupling rejection control then the model was decoupled. The system contains four input forces, which are basically the thrust provided by each propeller coupled to each rotor with a fixed angle. Pitch angle must change in order to maintain forward (backward) motion, which is accomplished by simultaneously increasing (decreasing) front (rear) rotor speed and decreasing (increasing) rear (front) rotor speed. The same method is used to change the roll angle for left and right motion. The motors in the front and rear spin counter-clockwise, while the motors in other motor positions rotate clockwise. This causes the yaw command to be generated by either raising or reducing the speed of the counter-clockwise motors while reducing or increasing the speed of the clockwise motors. The achieved goal here is the derivation of a model that properly reflects the physical properties enabling realistic simulations and is simple enough to be applied to controller design in the future. The system and controller's mathematical models were converted to matching Simulink models in order to make system simulations and investigations easier. The results show the accuracy and significant disturbance rejection of the nonlinear model. © 2024 IEEE.

The sensing capabilities of a soft arm are ofparamount importance to its overall performance as they allow precise control of the soft arm and enhance its interactionwith the surrounding environment. However, the actuationand sensing of a soft arm are not typically integrated into amonolithic structure, which would impede the arm’s movement and restrict its performance and application scope. Toaddress this limitation, this study proposes an innovativemethod for the integrated design of actuator structures andsensing. The proposed method combines the art of kirigamiwith soft robotics technology. In the proposed method, sensorsare embedded in the form of kirigami structures into actuatorsusing laser cutting technology, achieving seamless integrationwith a soft arm. Compared to the traditional amanogawakirigami and fractal-cut kirigami structures, the proposedmiddle-cut kirigami (MCK) structure does not buckle duringstretching and exhibits superior tensile performance. Based onthe MCK structure, an advanced interdigitated capacitivesensor with a high degree of linearity, which can significantlyoutperform traditional kirigami sensors, is developed. Theexperimental results validate the effectiveness of the proposedsoft arm design in actual logistics sorting tasks, demonstratingthat it is capable of accurately sorting objects based on sensorsignals. In addition, the results indicate that the developedcontinuum soft arm and its embedded kirigami sensors havegreat potential in the field of logistics automation *** work provides a promising solution for high-precisionclosed-loop feedback control and environmental interaction ofsoft arms.

Precise Localization of Multiple-AUVs through Reliability Assessment of Relative Observations

Journal of Institute of Control, Robotics and systems 2022年第6期28卷 558-565页

This paper describes a reliability assessment of relative observations for multiple autonomous underwater vehicles (multiple-AUVs). Swarm control and collision avoidance, the primary issues of a multiple-AUV system, intrinsically need precise localization of Multiple-AUVs, and relative observations of each autonomous underwater vehicle (AUV) are critical to improving localization precision. However, because relative observations are usually measured by ultrasonic sensors, the reliability of sensor data varies depending on the characteristics of each AUVs’ trajectories, as implied in previous our study. Therefore, this paper proposed a reliability assessment method based on the trajectories of each AUV and integrated the derived reliability of relative observations into the multiple-AUV localization algorithm. Consequently, localization performance with real sea experimental data is improved up to 77.4% compared with the previous independent navigation algorithm of each AUV and 60.6% compared with the previous study without the reliability assessment. We conclude that the proposed method is suitable for precise localization through relative observations. © ICROS 2022.

The buoyancy regulation system is an important part of the Miniature Underwater Vehicles. In this paper, the principle of buoyancy regulation system of micro submersible model is designed according to the actual requirements. The structure and working mechanism of spherical pump is analyzed, the leakage equation of spherical pump is derived from Navier-Stokes equation in spherical coordinates. And the influence of clearance,working pressure, rotational speed and medium viscosity on the leakage of spherical pump is studied. At the working pressure of 0.3 MPa, the clearance is under 0.015mm, the leakage is less than 1.5∗10-6m3/s. While the clearance is larger than 0.015mm, the leakage increases rapidly. When the clearance of the spherical pump is greater than 0.02mm, the speed increases from 1600rpm to 4800rpm and the volumetric efficiency increases from 55% to 83%. © 2023 IEEE.

The purpose of this study is to develop a fish feeding robot prototype that equipped with a water level control system for pond use and to propose an effective control scheme for the robot prototype and the water level control system. The system used in this paper consists of a feed storage tank, a feed distribution mechanism, a feed ejection mechanism, an ejector position turning mechanism, a water level control system, a base and a solar panel system for energy sources. The three mechanisms used three DC motors as actuator, respectively. The water level control system used a water pump to pump water out of pond when the level of water exceeds the maximum level limit, and an ultrasonic sensor to measure the level of water in pond. On - Off and proportional - integral (PI) controllers used to control DC motors of the three mechanisms, and the water level control system, respectively. Performances of the robot prototype with the water level control system were examined through laboratory scale experiments. The result of the conducted experiments are presented and discussed. © Published under licence by IOP Publishing Ltd.
