Human-robot collaborative maximizes the respective strengths of humans and robots, driving profound transformations in green intelligent manufacturing and supporting efficient completion of diverse disassembly tasks in remanufacturing. However, existing studies mainly focus on single End-of-Life (EOL) product scenarios. With the increasing variety and volume of EOL products, traditional single-line layouts and disassembly modes struggle to meet the demands of large-scale, multi-type product disassembly. To address this, this paper proposes a human-robot collaborative parallel two-sided destructive disassembly line balancing problem (HRC-PTDDLBP) for multi-product, multi-line scenarios. Firstly, a mixed-integer linear programming model is established for HRC-PTDDLBP to minimize weighted workstation count, smoothness index, and safety risk. To effectively derive the Pareto-optimal solutions, an improved Augmented ε-Constraint method (AUGMECON-2) is developed, which introduces slack variables and adaptive ε-step parameters to enhance convergence stability and solution diversity while avoiding weakly Pareto-optimal points. Secondly, an improved multi-objective discrete water wave optimization algorithm is developed for efficient model solving. The algorithm constructs the initial population based on task priorities and component non-disassemblability, incorporates a decoding strategy considering direction and task attribute conflicts, and enhances search performance through refined crossover, local search, and restart strategies. The model and algorithm correctness are validated within the GUROBI commercial solver’s scope. Benchmarking against seven state-of-the-art multi-objective algorithms under two-sided, human-robot non-destructive, and destructive disassembly modes, the proposed approach demonstrates superior performance. Finally, application to disassembly cases of discarded printers and televisions further validates the method. Compared with the second-best algorithm, the smoothness index is reduced by 87.0%, and safety risk is improved by 20.22%, alongside significant gains in line length reduction and idle time minimization. These results illustrate the comprehensive advantages of the proposed method in multi-product, multi-line human-robot collaborative disassembly line balancing, offering a practical and adaptable solution for real-world disassembly systems.
人机协作最大限度地发挥人与机器人各自的优势,推动绿色智能制造的深刻变革,支持再制造中各种拆卸任务的高效完成。然而,现有的研究主要集中在单一的生命终止(EOL)产品场景。随着EOL产品种类和数量的不断增加,传统的单线布局和拆卸方式难以满足大规模、多类型产品拆卸的需求。为了解决这一问题,本文提出了一种针对多产品、多生产线场景的人机协作并行双边破坏性拆解线平衡问题(HRC-PTDDLBP)。首先,建立了HRC-PTDDLBP的混合整数线性规划模型,以最小化加权工作站数、平滑指数和安全风险;为了有效地导出pareto最优解,提出了一种改进的增广ε-约束方法(AUGMECON-2),该方法引入松弛变量和自适应ε-步长参数,提高了收敛稳定性和解的多样性,同时避免了弱pareto最优点。其次,提出了一种改进的多目标离散水波优化算法,提高了模型求解的效率。该算法基于任务优先级和组件不可拆卸性构建初始种群,结合考虑方向和任务属性冲突的解码策略,通过优化交叉、局部搜索和重启策略提高搜索性能。在GUROBI商业求解器的范围内验证了模型和算法的正确性。通过对七种最先进的多目标算法在双边、人-机器人无损和破坏性拆卸模式下的基准测试,该方法显示出优越的性能。最后,通过对废旧打印机和电视机的拆解实例,进一步验证了该方法的有效性。与次优算法相比,平滑度指数降低了87.0%,安全风险提高了20.22%,同时在减少线路长度和最小化空闲时间方面取得了显著进展。这些结果说明了该方法在多产品、多线人机协同拆解线平衡中的综合优势,为实际拆解系统提供了一种实用且适应性强的解决方案。

The inherent limitations of single-agent systems in tackling complex tasks, combined with the inefficiencies of traditional multi-agent paradigms—where task decomposition requires distribution among multiple robots, resulting in resource redundancy and escalated costs. To address this critical constraint, a graph-driven Single-Robot Multi-Cognitive Agent System architecture is proposed. Firstly, scene graphs are constructed to transform unstructured visual data from the environment into graph-based triplets. By aligning these triplets with pre-constructed knowledge graphs, historical memories are activated through graph matching to inform system decision-making with precedented insights. Then, an attention-driven collaboration mechanism dynamically designates leader and supporter roles among the different agents, ensuring adaptive role assignment based on contextual demands. Complementing this, a global optimization framework facilitates the collective evolution of the Single-Robot Multi-Cognitive Agent System, enhancing both individual agent performance and inter-agent collaboration. Finally, the Model Context Protocol orchestrates robotic execution by harmonizing external resource utilization with computational processes, ensuring seamless translation of decision outputs into physical actions. Experimental results demonstrate that the method exhibits strong robustness and generalizability in dynamic disassembly queries.
单智能体系统在处理复杂任务时的固有局限性,以及传统多智能体模式的低效率——任务分解需要在多个机器人之间进行分配,导致资源冗余和成本上升。为了解决这一关键约束,提出了一种图驱动的单机器人多认知智能体系统架构。首先,构建场景图,将环境中的非结构化视觉数据转换为基于图的三元组。通过将这些三元组与预先构建的知识图对齐,通过图匹配激活历史记忆,从而根据先前的见解为系统决策提供信息。然后,基于注意力驱动的协作机制,在不同的代理之间动态指定领导者和支持者角色,确保基于上下文需求的适应性角色分配。与此相辅相成的是,全局优化框架促进了单机器人多认知智能体系统的集体进化,提高了个体智能体的性能和智能体之间的协作。最后,模型上下文协议通过协调外部资源利用和计算过程来协调机器人的执行,确保将决策输出无缝地转化为物理行动。实验结果表明,该方法对动态拆解查询具有较强的鲁棒性和通用性。

iLSPR: A Learning-based Scene Point-cloud Registration method for robotic spatial awareness in intelligent manufacturing 基于学习的智能制造机器人空间感知场景点云配准方法

A critical capability for intelligent manufacturing is the ability for robotic systems to understand the spatial operation environment – the ability for robots to precisely recognize and estimate the spatial positions and orientations of objects in industrial scenes. Existing scene reconstruction methods are designed for general settings with low precision needs of objects and abundant data. However, manufacturing hinges on high object precision and operates with limited data. Addressing such challenges and limitations, we propose a novel Learning-based Scene Point-cloud Registration framework for automatic industrial scene reconstruction (iLSPR). The proposed iLSPR framework leverages point cloud representation and integrates three key innovations: (i) a Multi-Feature Robust Point Matching Network (MF-RPMN) that learns from both raw data and deep features of the objects to accurately align point clouds, (ii) a Geometric-Primitive-based Data Generation (GPDG) method for efficient synthetic data generation, and (iii) a digital model library of industrial target objects. During operation, vision sensors capture point clouds in the scenes, and the iLSPR method registers high-fidelity object models in the scenes using MF-RPMN, pre-trained with GPDG-generated data. We introduce an Industrial Scene Object Point-cloud Registration (ISOPR) dataset in IsaacSim to benchmark performance. Experimental results demonstrate that iLSPR significantly outperforms existing methods in accuracy and robustness. We further validate the approach on a real-world robotic manufacturing system, demonstrating reliable digital reconstruction of industrial scenes.
智能制造的一个关键能力是机器人系统理解空间操作环境的能力——机器人精确识别和估计工业场景中物体的空间位置和方向的能力。现有的场景重建方法都是针对一般场景而设计的,对物体的精度要求不高,数据量大。然而,制造业依赖于高物体精度和有限的数据。针对这些挑战和限制,我们提出了一种新的基于学习的场景点云配准框架,用于自动工业场景重建(iLSPR)。提出的iLSPR框架利用点云表示,并集成了三个关键创新:(i)多特征鲁棒点匹配网络(MF-RPMN),从原始数据和对象的深层特征中学习,以精确对齐点云;(ii)基于几何原语的数据生成(GPDG)方法,用于高效的合成数据生成;(iii)工业目标对象的数字模型库。在操作过程中,视觉传感器捕获场景中的点云,iLSPR方法使用MF-RPMN注册场景中的高保真目标模型,并使用gpdg生成的数据进行预训练。我们在IsaacSim中引入一个工业场景对象点云配准(ISOPR)数据集来对性能进行基准测试。实验结果表明,iLSPR在准确性和鲁棒性方面明显优于现有方法。我们进一步在现实世界的机器人制造系统中验证了该方法,展示了工业场景的可靠数字重建。

A temporal spatial human digital twin approach for modeling human behavior with uncertainty 不确定性人类行为建模的时空数字孪生方法

Modeling human behavior is paramount in the process of human-robot interaction (HRI). Human motion during HRI is uncertain. Even when the same individual performs the same action, it is impossible to ensure that the motion trajectory will be identical every time. These factors make modeling human behavior extremely challenging. Beyond human uncertainty, there are dynamic temporal spatial dependencies in HRI. Effectively capturing uncertainty while fully integrating temporal spatial features presents a significant challenge. Moreover, representing human behavior solely through human skeleton is insufficient. Recently, human digital twins have been developed to represent human geometry. However, current human digital twins are not well-suited for dynamic HRI scenarios, as they struggle to accurately depict high-dimensional human parameters, leading to issues such as nonlinear mapping and joint drift. In summary, existing methods find it difficult to address the human uncertainty, the temporal spatial dependencies, and the high-dimensional human parameters. To address the above challenges, this study proposes a temporal spatial human digital twin (TSHDT) for modeling human behavior in HRI. The TSHDT is based on predicted human skeletons and integrates forward and inverse kinematics along with diffusion prior distribution to represent high-dimensional human parameters, thus preventing joint drift and nonlinear mapping between joints. In developing the TSHDT, we introduce the human robot temporal spatial (HRTS) diffusion model to mitigate the uncertainty in human motion. The unique diffusion and denoising processes of the HRTS diffusion model can effectively submerge uncertainty in noise and accurately predict human motion during subsequent denoising steps. To ensure that the denoising process favors accuracy over diversity, we propose the temporal spatial fusion graph convolutional network (TSFGCN) to capture temporal spatial features between humans and robots, embedding them into the HRTS diffusion model. Finally, the effectiveness of the TSHDT was validated via predictive collision detection in human-robot fabric cutting experiments. Results demonstrate that the proposed method accurately models human behavior in collision detection experiments, achieving outstanding F1 scores.
在人机交互(HRI)过程中,人类行为建模是至关重要的。HRI期间的人体运动是不确定的。即使同一个体进行相同的动作,也不可能保证每次的运动轨迹都是相同的。这些因素使得模拟人类行为极具挑战性。除了人类的不确定性之外,HRI还存在动态的时空依赖性。在充分整合时空特征的同时,有效地捕捉不确定性是一项重大挑战。此外,仅仅通过人体骨骼来表现人类行为是不够的。最近,人类数字双胞胎已经被开发出来,以代表人类的几何形状。然而,目前的人类数字孪生体并不适合动态HRI场景,因为它们难以准确描述高维人类参数,从而导致非线性映射和关节漂移等问题。综上所述,现有方法难以处理人为不确定性、时空依赖性和高维人为参数。为了解决上述挑战,本研究提出了一个时空人类数字孪生(TSHDT)来模拟HRI中的人类行为。TSHDT基于预测的人体骨骼,将正运动学和逆运动学以及扩散先验分布相结合,以表示高维人体参数,从而防止关节漂移和关节之间的非线性映射。在开发TSHDT时,我们引入了人-机器人时空(HRTS)扩散模型来减轻人体运动中的不确定性。HRTS扩散模型独特的扩散和去噪过程可以有效地消除噪声中的不确定性,并在后续去噪步骤中准确预测人体运动。为了确保去噪过程更有利于准确性而不是多样性,我们提出了时空融合图卷积网络(TSFGCN)来捕获人类和机器人之间的时空特征,并将其嵌入到HRTS扩散模型中。最后,在人机裁剪实验中,通过预测碰撞检测验证了TSHDT算法的有效性。结果表明,该方法在碰撞检测实验中准确地模拟了人类行为,取得了优异的F1分数。

In the context of cloud manufacturing service, scheduling manufacturing tasks is a crucial area of research because it directly influences service quality and efficiency. As intelligent manufacturing technologies advance, edge manufacturing service providers have gained increasingly flexible ability, enabling them to adjust local production schedules to adapt cloud manufacturing tasks. However, because local manufacturing information is private, traditional centralized cloud manufacturing scheduling methods cannot fully leverage edge flexibility to collaboratively schedule multi-source manufacturing tasks (including both cloud manufacturing tasks and local tasks of edge service providers) without risking the disclosure of sensitive information, thereby limiting improvements in both performance and efficiency of cloud manufacturing service. Therefore, we propose a privacy-preserving cloud-edge collaborative decision-making approach based on auction theory to schedule multi-source manufacturing tasks. First, a mathematical model that accounts for the objectives of both service providers and demanders is established to characterize the collaborative scheduling of multi-sourced tasks. Subsequently, a cloud-edge collaborative scheduling decision framework is introduced. Building upon this, a multi-stage scheduling method based on combinatorial iterative auctions is proposed, featuring novel bidding with a flexible execution timeline and distributed winner determination process incorporating bid consolidation mechanisms to enhance the efficiency of cloud-edge collaborative decision. Finally, to validate the superiority of the proposed method, computational experiments are conducted, comparing it with traditional centralized manufacturing task scheduling methods. The results present that the proposed method not only completes cloud manufacturing tasks within a relatively shorter makespan but also provides higher-value manufacturing services to demanders. Moreover, as the cloud manufacturing task load increases, this advantage becomes even more pronounced.
在云制造服务背景下,制造任务调度是一个重要的研究领域,因为它直接影响到服务质量和效率。随着智能制造技术的进步,边缘制造服务商获得了越来越灵活的能力,使他们能够调整本地生产计划以适应云制造任务。然而,由于本地制造信息是私有的,传统的集中式云制造调度方法无法充分利用边缘灵活性,在不泄露敏感信息的情况下协同调度多源制造任务(包括云制造任务和边缘服务提供商的本地任务),从而限制了云制造服务的性能和效率提升。因此,我们提出了一种基于拍卖理论的多源制造任务调度的隐私保护云边缘协同决策方法。首先,建立了考虑服务提供者和需求者目标的数学模型来表征多源任务协同调度。随后,介绍了一种云边缘协同调度决策框架。在此基础上,提出了一种基于组合迭代拍卖的多阶段调度方法,采用具有灵活执行时间的新型竞价和包含竞价整合机制的分布式中标人确定过程,提高了云边缘协同决策的效率。最后,为了验证该方法的优越性,进行了计算实验,并与传统的集中式制造任务调度方法进行了比较。结果表明,该方法不仅可以在相对较短的makespan内完成云制造任务,而且可以为需求者提供更高价值的制造服务。此外,随着云制造任务负载的增加,这种优势变得更加明显。

A hierarchical human behavior modeling framework for safe and efficient human-robot collaborative assembly 安全高效人机协同装配的分层人行为建模框架
IF 11.4 1区 计算机科学 Q1 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-12-10 DOI: 10.1016/j.rcim.2025.103202

Human-robot collaboration (HRC) offers promising solutions in industrial assembly by combining human dexterity and robot efficiency. However, the proximity of the human and robot raises safety concerns that can limit efficiency. Previous studies have typically addressed safety or efficiency separately, relying on incomplete models of human behavior, which has led to robot control strategies with limited adaptability. To bridge this gap, this paper proposes a hierarchical human behavior modeling framework that integrates human motion prediction (HMP) and human action segmentation. The proposed model captures both the fine-grained motion dynamics and the higher-level task structure, enabling a more complete and context-aware understanding of human behavior. The model can enhance robot decision-making for both proactive safety mechanisms and dynamic task allocation. HMP compares three predictive models (Convolutional Neural Networks - Long Short-Term Memory (CNN-LSTM), Spatial-Temporal Graph Convolutional Networks (ST-GCN), Transformer). CNN-LSTM and ST-GCN outperformed Transformer, demonstrating better short-term predictive accuracy. Human action segmentation includes feature extraction, dimensionality reduction, clustering, and two-stage temporal segmentation. The HMP (CNN-LSTM) based features achieve the highest clustering performance. Two-stage segmentation demonstrates high accuracy, achieving normalized edit distances (NED) of 0.029 and 0.07 for task-level and sub-task-level segmentation, respectively. Evaluation results show that proactive collision avoidance using predicted motions increased safety distance (from 0.4633 m to 0.4717 m), while dynamic task allocation based on action segmentation improves robot efficiency (from 84.95 % to 98.56 %). These results validate the effectiveness of the proposed hierarchical human behavior modeling framework in simultaneously enhancing safety and efficiency in HRC assembly.
人机协作(HRC)通过结合人的灵活性和机器人的效率,为工业装配提供了有前途的解决方案。然而,人类和机器人的接近引发了安全问题,这可能会限制效率。以前的研究通常是分别解决安全或效率问题,依赖于不完整的人类行为模型,这导致机器人控制策略具有有限的适应性。为了弥补这一缺陷,本文提出了一种将人体运动预测(HMP)和人体动作分割相结合的分层人体行为建模框架。所提出的模型既捕获了细粒度的运动动态,又捕获了更高级别的任务结构,从而能够对人类行为进行更完整和上下文感知的理解。该模型可以增强机器人的主动安全机制和动态任务分配的决策能力。HMP比较了三种预测模型(卷积神经网络-长短期记忆(CNN-LSTM),时空图卷积网络(ST-GCN), Transformer)。CNN-LSTM和ST-GCN表现优于Transformer,表现出更好的短期预测准确性。人体动作分割包括特征提取、降维、聚类和两阶段时间分割。基于HMP (CNN-LSTM)的特征实现了最高的聚类性能。两阶段分割具有较高的准确率,任务级和子任务级分割的归一化编辑距离(NED)分别为0.029和0.07。评估结果表明,基于预测运动的主动避撞提高了机器人的安全距离(从0.4633 m提高到0.4717 m),而基于动作分割的动态任务分配提高了机器人的效率(从84.95%提高到98.56%)。这些结果验证了所提出的分层人类行为建模框架在提高HRC装配安全性和效率方面的有效性。

Target-oriented collision-free robot grasping using task-attendance teachers-student knowledge distillation for various dense-clutter scenarios 基于任务出勤师生知识蒸馏的面向目标无碰撞机器人抓取
IF 11.4 1区 计算机科学 Q1 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-12-10 DOI: 10.1016/j.rcim.2025.103201

The target-oriented collision-free robot grasping in dense-clutter scenarios has made significant progress. However, the prior studies primarily focus on the complex problem brought about by an increase in object quantity. Actually, the various scenarios will also result in the challenge. That means skill models will inevitably start to obtain bloat, as more subtasks appear. Our previous study presents a multi-teacher distillation strategy, thereby effectively avoiding bloat. Unfortunately, it still has trouble in execution capability when the scenarios have more subtasks and highly similar subtasks. The root cause is attributed to the inadequate capability of distilled student in subtask identification. It is naive to develop the subtask classifier based on the traditional data-driven way when human experience fails to work. Therefore, we propose a dataset-free classifier by migrating the classification capability of teachers to the student. Then, we further propose a task-attendance teachers-student knowledge distillation strategy to afford the various scenarios involving more and highly similar subtasks, thus significantly enhancing the performance of grasping. And we also leverage the language instruction to ensure the mask map of target object through LLM, improving the intuitiveness of human-robot cooperation. Extensive comparative experiment verifies the advantage of our framework. We measure the capability of teachers-student distillation, and value of dataset-free classifier in our framework. Importantly, the performance of segmentation strategy is tested under ambiguous instruction, visual occlusion, and color conflict. Furthermore, the excellent generalization and robustness are exhibited according to the real-world experiments involving unseen object, unseen task modality, and disturbance existing.
面向目标的无碰撞机器人在密集杂波环境下抓取的研究取得了重大进展。然而,以往的研究主要集中在对象数量增加所带来的复杂问题上。实际上,各种各样的场景也会带来挑战。这意味着随着更多子任务的出现,技能模型将不可避免地开始膨胀。我们之前的研究提出了一个多教师蒸馏策略,从而有效地避免了膨胀。不幸的是,当场景具有更多的子任务和高度相似的子任务时,它在执行能力方面仍然存在问题。其根本原因在于学生在子任务识别方面的能力不足。当人的经验不起作用时,基于传统的数据驱动方法开发子任务分类器是幼稚的。因此,我们提出了一种无数据集的分类器,将教师的分类能力转移到学生身上。在此基础上,我们进一步提出了任务-考勤-师生知识蒸馏策略,以应对涉及更多且高度相似的子任务的各种场景,从而显著提高了抓取性能。并且利用语言指令通过LLM保证目标物体的掩模图,提高了人机合作的直观性。大量的对比实验验证了该框架的优越性。在我们的框架中,我们衡量了师生蒸馏的能力和无数据集分类器的价值。重要的是,在模糊指令、视觉遮挡和颜色冲突的情况下测试了分割策略的性能。此外,通过对不可见目标、不可见任务模态和存在干扰的实际实验,证明了该方法具有良好的泛化和鲁棒性。

Design of support head with joint-synchronized structure and tuned mass damper for robotic mirror milling 机器人铣镜关节同步结构和调谐质量阻尼器支撑头设计
IF 11.4 1区 计算机科学 Q1 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-12-08 DOI: 10.1016/j.rcim.2025.103200

Machined thin-walled parts are critical to lightweight aerospace structures; however, their low stiffness poses significant challenges in controlling deformation and vibrations during their machining. To counteract these force-induced errors, robotic mirror milling has emerged as a promising technique, because a support robot can actively neutralize the cutting forces. However, the support robot requires an appropriate end-effector to protect the workpiece surface, while providing stable support. In this study, a support head with plastic rollers and a multi-branched tuned mass damper (TMD) is developed. The support head, synchronized with the Joint 6 of the support robot, contacts the thin-walled part via plastic rollers. A follow-up motion plan algorithm is proposed for the support head to synchronize its motion with the milling tool. The multi-branched TMD is designed to suppress the vibrations of the thin-walled parts and support head in different directions, thus ensuring an effective contact between them. A frequency-response function model for the TMD is proposed for parameter design. Simulations and experiments confirm that the designed motion-planning algorithm reduces the velocity of Joint 6 by 78.6 %, while the TMD decreases the machined surface roughness by 32.8 % and 21.4 % at axial depths of cut of 1.0 and 1.5 mm, respectively. The results demonstrate that the joint-synchronized support head, combined with the multi-branched TMD, effectively ensures stable support to the workpiece, while preventing damage to its surface.
机加工薄壁件是航空航天轻量化结构的关键;然而,它们的低刚度在加工过程中对控制变形和振动提出了重大挑战。为了抵消这些力引起的误差,机器人镜面铣削已经成为一种很有前途的技术,因为支撑机器人可以主动抵消切削力。然而,支撑机器人需要一个合适的末端执行器来保护工件表面,同时提供稳定的支撑。本文设计了一种带有塑料滚子和多分支调谐质量阻尼器的支撑头。支撑头与支撑机器人的关节6同步,通过塑料滚轮与薄壁件接触。提出了一种支撑头与铣刀同步运动的跟踪运动规划算法。多分支TMD的设计是为了抑制薄壁零件和支承头在不同方向上的振动,从而保证它们之间的有效接触。提出了TMD的频率响应函数模型,用于参数设计。仿真和实验结果表明,在轴向切削深度为1.0 mm和1.5 mm时,所设计的运动规划算法可使关节6的切削速度降低78.6%,而TMD可使加工表面粗糙度分别降低32.8%和21.4%。结果表明,联合同步支撑头与多分支TMD相结合,有效地保证了工件的稳定支撑,同时防止了工件表面的损伤。

Trajectory optimization is vital for improving the operational efficiency and reliability of industrial robotic arms. However, increasing task execution speed frequently induces sharp fluctuations in joint torque, which elevates energy consumption, places excessive stress on actuators, and excites structural vibrations. To tackle these issues, this study introduces a unified time–torque optimization framework that combines predictive modeling with heuristic search. The framework adopts a neural network incorporating frequency-domain correlation and a delay-aware mechanism to model dynamic torque variations. Based on the predicted torque profiles, the robot’s motion trajectory is parameterized by quintic polynomials, and a multi-objective loss function is constructed to jointly minimize execution time and torque variation rate. Particle Swarm Optimization (PSO) is employed to perform a global search for intermediate joint velocities and accelerations, improving convergence toward near-optimal solutions. Experiments on a six-axis industrial robotic platform demonstrate that the proposed method effectively reduces execution time and smooths torque transitions, confirming its practicality for industrial applications.
轨迹优化是提高工业机械臂运行效率和可靠性的关键。然而,任务执行速度的提高往往会引起关节扭矩的急剧波动,从而增加能量消耗,对执行器施加过大的应力,并激发结构振动。为了解决这些问题,本研究引入了一个统一的时间-扭矩优化框架,该框架将预测建模与启发式搜索相结合。该框架采用结合频域相关和延迟感知机制的神经网络对动态转矩变化进行建模。基于预测的转矩曲线,采用五次多项式参数化机器人运动轨迹,构建多目标损失函数,共同最小化执行时间和转矩变化率。采用粒子群算法(PSO)对中间关节速度和加速度进行全局搜索,提高了接近最优解的收敛性。在六轴工业机器人平台上的实验表明,该方法有效地缩短了执行时间,平滑了转矩转换,验证了其在工业应用中的实用性。

Real-time surface defect detection in steel strips requires high accuracy under computational constraints. Existing methods often struggle to detect low-contrast defects in complex backgrounds while maintaining computational efficiency. This paper proposes MSR-Det, a lightweight network built on a multi-scale semantic refinement framework to address this challenge. The core innovations include: a Hierarchical Texture Enhancement Module (HTEM) that strengthens discriminative textural patterns, a Specific Cross-Level Interaction Module (SCLIM) that facilitates granular feature fusion across network depths, and a Feature Enhancement Module (FEM) that refines defect representations through deep-to-shallow semantic guidance. The architecture further incorporates two key modules: a Lightweight Large-Kernel Bottleneck Module (LLKBM) for efficient receptive field expansion, and an Adaptive Gating Spatial Pyramid Pooling (AGSPP) for dynamic multi-scale context integration. Extensive experiments on NEU-DET, GC10-DET, and our industrial SS-DET dataset demonstrate that MSR-Det achieves state-of-the-art performance of 86.6% Mean Average Precision at 50% Intersection over Union (mAP50) on SS-DET with only 5.0M parameters, also attaining a real-time speed of 180 FPS. This work provides a robust and practical solution for automated visual inspection in industrial settings, effectively balancing high precision with operational efficiency.
