摘要:

在本研究中,我们提出了MoMa-Pos框架,用于优化移动操作机器人的基座放置,聚焦于同时存在刚性物体和铰接物体的环境中的导航-操作任务。在此类环境中基座放置尤为关键,若未充分考虑物体的运动学特性,不当的定位会严重阻碍任务执行。MoMa-Pos通过优先处理与任务相关的关键物体来选择性重建环境,既提升了计算效率,又确保仅处理必要的运动学细节。该框架利用基于图的神经网络预测物体重要性,实现聚焦式建模同时减少不必要的计算。此外,MoMa-Pos将逆可达性地图与环境运动学特性相结合,为特定机器人模型识别可行的基座位置。大量评估表明,MoMa-Pos在真实和模拟环境中均优于现有方法,在不同场景和机器人模型下具备更优的效率、精度和适应性。补充材料可访问https://yding25.com/MoMa-Pos获取。

英文摘要:

In this work, we present MoMa-Pos, a framework that optimizes base placement for mobile manipulators, focusing on navigation-manipulation tasks in environments with both rigid and articulated objects. Base placement is particularly critical in such environments, where improper positioning can severely hinder task execution if the object's kinematics are not adequately accounted for. MoMa-Pos selectively reconstructs the environment by prioritizing task-relevant key objects, enhancing computational efficiency and ensuring that only essential kinematic details are processed. The framework leverages a graph-based neural network to predict object importance, allowing for focused modeling while minimizing unnecessary computations. Additionally, MoMa-Pos integrates inverse reachability maps with environmental kinematic properties to identify feasible base positions tailored to the specific robot model. Extensive evaluations demonstrate that MoMa-Pos outperforms existing methods in both real and simulated environments, offering improved efficiency, precision, and adaptability across diverse settings and robot models.
