Future-Oriented Navigation: Dynamic Obstacle Avoidance with One-Shot Energy-Based Multimodal Motion Prediction
- 基于能量模型的单次操作生成多步高分辨率运动预测
- 通过聚类分组障碍物并构建几何约束,提升避障效率
- 适用于仓库等复杂动态场景,适合需要快速决策的移动机器人
本文提出一种集成方法,用于在动态不确定环境中安全高效地控制移动机器人。该方法包含两个关键步骤:单次操作的多模态运动预测,用于预判动态障碍物行为;以及将预测结果融入运动规划的模型预测控制。运动预测采用基于能量的神经网络,在一次计算中生成高分辨率、多步预测结果,并将其转化为数学约束的几何形状。为提高性能与效率,预测出的障碍物通过无监督方式按距离聚类处理,而非单独建模。整体无碰撞导航由设计用于主动避障的模型预测控制实现。所提方法在多种典型仓储场景下进行评估,结果表明其优于现有动态避障方法。
原文摘要 · Abstract (English)
This paper proposes an integrated approach for the safe and efficient control of mobile robots in dynamic and uncertain environments. The approach consists of two key steps: one-shot multimodal motion prediction to anticipate motions of dynamic obstacles and model predictive control to incorporate these predictions into the motion planning process. Motion prediction is driven by an energy-based neural network that generates high-resolution, multi-step predictions in a single operation. The prediction outcomes are further utilized to create geometric shapes formulated as mathematical constraints. Instead of treating each dynamic obstacle individually, predicted obstacles are grouped by proximity in an unsupervised way to improve performance and efficiency. The overall collision-free navigation is handled by model predictive control with a specific design for proactive dynamic obstacle avoidance. The proposed approach allows mobile robots to navigate effectively in dynamic environments. Its performance is accessed across various scenarios that represent typical warehouse settings. The results demonstrate that the proposed approach outperforms other existing dynamic obstacle avoidance methods.
