提出软硬一体方案,实现杂乱环境下的高效连续抓取

Towards Reliable Sequential Object Picking in Clutter: The Runner-up Solution to RGMC 2025

  • 设计可抓取柔性和刚性物体的多功能夹爪与遮挡关系表征方法
  • 在实验室与竞赛中均实现高成功率连续抓取,获RGMC2025第二名
  • 适合工业场景中需连续分拣复杂物品的机器人系统参考

在工业场景中,稳定高效的杂乱环境抓取是长期挑战。尽管近期研究已在单次抓取任务上取得较高成功率,但针对更复杂的连续目标搜索与排序任务,仍缺乏成熟解决方案。本文基于杂乱环境抓取基准(CEPB),提出应对第10届国际机器人抓取与操作竞赛(RGMC 2025)抓取赛道的参赛方案。该任务面临两大挑战:一是需对多样物体(包括刚性与柔性)实现鲁棒且防碰撞的抓取;二是需高效搜索目标物,对去杂与搜寻策略提出严苛要求。为此,我们构建了集物体识别、去杂与多模态抓取于一体的软硬件一体化流程,核心贡献包括多功能夹爪的硬件设计及杂乱空间中物体分布与遮挡关系的新型表示方法。该流程实现了杂乱环境中物体的高效识别、搜索与连续抓取,在实验室测试与竞赛场景中表现优异,最终在RGMC 2025抓取赛道中获得第二名。

原文摘要 · Abstract (English)

As a long-standing challenge in robotic manipulation, stable and efficient grasping in cluttered environments is of great importance in industrial settings. While recent studies have achieved relatively high success rates in grasping from clutter, there remain few mature solutions for more demanding tasks such as sequential object search and sorting. This work addresses sequential object picking in cluttered environments based on the Cluttered Environment Picking Benchmark (CEPB) and presents our solution to the Pick-in-Clutter track of the 10th Robotic Grasping and Manipulation Competition (RGMC) at ICRA 2025. The task poses several key challenges. First, it requires robust and collision-aware grasping with high success rates across a diverse set of objects, including both rigid and deformable ones. Second, it demands efficient search for target objects, which places stringent requirements on the decluttering and searching strategies of the solution. To address the above challenges, we design an integrated hardware-software pipeline that combines object recognition, decluttering, and multi-modal grasping. The main contributions include the hardware design of a multifunctional gripper and novel representations for object distribution and occlusion relationships in cluttered space. This pipeline enables efficient recognition, search, and sequential grasping of objects in clutter, demonstrating strong performance in both laboratory tests and competition scenarios, and ultimately achieving second place in the Pick-in-Clutter track of the RGMC 2025.
