Obstacle detection plays a crucial role in unmanned vehicle path planning, demanding heavy computational resources for accurate detection, often challenging real-time requirements. In this study, we introduce a dual LiDAR approach for obstacle detection and propose a drivable space detection algorithm based on multi-spatial feature fusion for sampling and segmentation. Our method enhances the accuracy and efficiency of obstacle point cloud segmentation compared to other ground-based point cloud segmentation algorithms. © 2024 IEEE.

The development of a dynamic model for a popular implemented solar power plant is a critical task for power engineers aiming to enhance the plant’s performance and reliability. In this study, we utilized the prediction error method (PEM), a robust algorithm for system identification, to capture the plant’s operational characteristics with precision. Additionally, we employed both recursive and hierarchical algorithms to identify the system parameters effectively. The results from each identification method are rigorously quantified and analyzed, allowing for a detailed comparison of their performance. This comprehensive evaluation not only highlights the strengths and weaknesses of each approach, but also provides valuable insights into their practical applications in the context of solar power systems. © The Author(s) 2024.

This paper studies the partial information defense game with an active target. This type of game considers the influence of both sensing limitation and the moving target, which are common in the real-world conditions. Compared with the stationary target scenario, the defender has more flexibility to capture the intruder when the target is active. Inspired by previous works, we separate the game into four phases and obtain optimal strategies for all agents in each phase, respectively. The lower bound of defender’s winning probability is obtained under some mild assumptions, which is higher than that in the stationary target scenario. An illustrative example is presented to demonstrate the efficacy of the theoretical results. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Multi-agent systems must learn to communicate and understand interactions between agents to achieve cooperative goals in partially observed tasks. However, existing approaches lack a dynamic directed communication mechanism and rely on global states, thus diminishing the role of communication in centralized training. Thus, we propose the Transformer-based graph coarsening network (TGCNet), a novel multi-agent reinforcement learning (MARL) algorithm. TGCNet learns the topological structure of a dynamic directed graph to represent the communication policy and integrates graph coarsening networks to approximate the representation of global state during training. It also utilizes the Transformer decoder for feature extraction during execution. Experiments on multiple cooperative MARL benchmarks demonstrate state-of-the-art performance compared to popular MARL algorithms. Further ablation studies validate the effectiveness of our dynamic directed graph communication mechanism and graph coarsening networks.

In virtual worlds and robotic teleoperation scenarios, this sense of touch must be artificially reconstructed by stimulation of the human body (usually by the hand) to produce the haptic features required for enhanced realism and human performance. With the development of virtual reality and augmented reality technologies, interacting directly with virtual objects with haptic feedback is receiving more and more attention. In this study, a three degree of freedoms (3-DOFs) haptic feedback device was proposed, which can generate a force haptic feedback by skin stretching at the fingertips. The device employed a slider-crank linkage mechanism and a curved- W -shaped five-bar linkage mechanism, with the motor driving the slider-crank linkage mechanism mounted on the back of the finger and the two motors driving the curved- W-shaped five-bar linkage mechanism mounted on both sides of the finger. In addition, this study also analyzes the kinematics and statics of the structure of the proposed device, which provides the actual value of pressure 2.92 N slightly larger than the theoretical value of 2.67 N. It also verifies the reasonableness of the design by analyzing the results and experiments, and the experimental accuracy of the direction recognition gradually becomes larger with the increasing of the value of the condition. This study can contribute to the understanding of human multimodal tactile perception mechanisms on the one hand, and provide motivation for robotics and haptics on the other. © 2024 IEEE.

The mechanism of sensorimotor integration involves how the brain integrates multisensory information to form a unified perception of movement and space. Precision grasping, a hand function unique to humans, is the foundation for various dexterous manipulations. However, the sensorimotor integration mechanism underlying precision grasping remains unclear, particularly when there is a discrepancy between visual and tactile information. This study aims to develop an immersive mixed-reality-based precision grasping control system, synchronously collecting multiple physiological signals to reveal the control mechanisms of precision grasping from two perspectives: central-peripheral coordination and perception-movement coupling. The results show that during precision grasping, conflicts between visual and tactile perception induce differences in oscillatory activity across multiple brain regions (p © 2024 IEEE.
