摘要:

效率与可靠性在机器人料箱拣选中至关重要,它们直接影响自动化工业流程的生产率。然而,传统方法要求物体静止、碰撞场景固定,导致部署受限、操作效率低下且流程不可靠。本文提出动态料箱拣选框架(Dynamic Bin-Picking Framework,DBPF),打破了传统的静态假设。DBPF赋予机器人反应能力,可在避让移动料箱等动态障碍物的同时,拣选多个任意移动的物体。结合场景级位姿生成,所提出的位姿选择指标利用趋势感知可操作性网络(Tendency-Aware Manipulability Network)优化吸持位姿的确定。速度匹配、动态障碍物避让、复看策略等针对任务的启发式设计提升了拣选成功率与可靠性。实证实验证明了这些组件的重要性。我们的方法平均成功率达84%,优于最相近基线的60%,关键在于实现了零碰撞。在多种动态场景下的进一步评估表明,DBPF在动态料箱拣选中表现鲁棒。结果显示,该框架为动态环境下高效可靠的机器人料箱拣选提供了颇具前景的解决方案。

英文摘要:

Efficiency and reliability are critical in robotic bin-picking as they directly impact the productivity of automated industrial processes. However, traditional approaches, demanding static objects and fixed collisions, lead to deployment limitations, operational inefficiencies, and process unreliability. This paper introduces a Dynamic Bin-Picking Framework (DBPF) that challenges traditional static assumptions. The DBPF endows the robot with the reactivity to pick multiple moving arbitrary objects while avoiding dynamic obstacles, such as the moving bin. Combined with scene-level pose generation, the proposed pose selection metric leverages the Tendency-Aware Manipulability Network optimizing suction pose determination. Heuristic task-specific designs like velocity-matching, dynamic obstacle avoidance, and the resight policy, enhance the picking success rate and reliability. Empirical experiments demonstrate the importance of these components. Our method achieves an average 84% success rate, surpassing the 60% of the most comparable baseline, crucially, with zero collisions. Further evaluations under diverse dynamic scenarios showcase DBPF's robust performance in dynamic bin-picking. Results suggest that our framework offers a promising solution for efficient and reliable robotic bin-picking under dynamics.
