双工业机械臂协同作业的动态路径规划与优化算法OA
Dynamic path planning and optimization algorithm for collaborative operation of dual industrial manipulators
针对双工业机械臂采用传统算法在高维动态场景中存在的搜索效率低、局部最优和避障迟滞现象,研究采用引力函数控制的快速扩展随机树(RRT)并结合动态窗口法(DWA),构建全局-局部双层路径优化框架;同时设计任务调度状态池,实现协同机械臂在共享空间中的路径互避与节拍同步.基于ROS 2与Gazebo平台,对双工业机械臂在高密度障碍与动态干扰环境下的协同作业进行了仿真评估;对比未优化路径,启用动态路径规化与优化算法后平均路径长度缩短了约18.0%,平均能耗降低了约18.0%,冲突次数由3次降为0次,调度延迟也明显缩短.随后将算法部署于实际金属部件装配单元,完成为期两周的连续抓取-插配任务验证,平均规划时间保持在85 ms以内,平均姿态误差控制在±2.3 mm,未发生停机冲突,证明算法具备良好工程可行性与稳定性.研究表明,引力偏置与动态避障的耦合策略能够显著提高双工业机械臂协同作业的路径质量与系统鲁棒性,为智能制造生产线的柔性调度提供有效技术支撑.
Aiming at the problems of low search efficiency,local optimality and obstacle avoidance hysteresis in high-dimensional dynamic scenarios when traditional algorithms are applied to dual industrial manipulators,a global-local two-layer path optimiza-tion framework was constructed.Specifically,the Rapidly exploring Random Tree(RRT)controlled by a gravitational function was adopted and combined with the Dynamic Window Approach(DWA).Meanwhile,a task scheduling state pool was designed to realize path mutual avoidance and beat synchronization of cooperative manipulators in the shared space.A simulation evaluation of dual industrial manipulators cooperative operation in high-density obstacle and dynamic interference environments was conduc-ted based on the ROS 2 and Gazebo platforms.Compared with the unoptimized path,after the dynamic path planning and optimi-zation algorithm was enabled,the average path length was shortened by approximately 18.0%,the average energy consumption was reduced by about 18.0%,the number of conflicts decreased from 3 to 0,and the scheduling delay was also significantly short-ened.Subsequently,the algorithm was deployed in an actual metal component assembly unit to complete a two-week continuous grasping and insertion task verification.The average planning time was maintained within 85 ms,the average pose error was con-trolled within±2.3 mm,and no shutdown conflicts occurred.These results demonstrate that the algorithm has good engineering feasibility and stability.Studies have shown that the coupled strategy of gravity bias and dynamic obstacle avoidance can signifi-cantly improve the path quality and system robustness of dual industrial manipulators collaborative operations,and provide effec-tive technical support for the flexible scheduling of intelligent manufacturing production lines.
