Robust Mobile Robot Path Planning via LLM-Based Dynamic Waypoint Generation
- 用大模型将自然语言指令转为可执行路径点
- Llama3.1在复杂环境路径规划中速度最快、成功率最高
- 适合需要灵活响应的复杂场景机器人应用
复杂环境中移动机器人路径规划仍是重大挑战,尤其在实现高效、安全和鲁棒路径方面。传统路径规划方法如深度强化学习(DRL)模型通常针对特定起点与目标位置训练,仅在条件匹配时表现良好。本文提出一种新型路径规划框架,通过嵌入大型语言模型(LLM),使移动机器人具备理解自然语言指令并自主生成高效、无碰撞导航路径的能力。该框架利用LLM将高层用户输入转化为可行动作路径点,并在遇到障碍物时动态调整路径。我们在三个逐步复杂的环境中对所提方法进行了实验评估,结果表明使用Llama3.1模型的方案在路径规划时间、路径点生成成功率及避障能力上均优于其他LLM模型,凸显了大模型在提升机器人复杂决策能力方面的潜力。本框架构建了更安全可靠的导航系统,为未来研究开辟新方向。代码已开源于GitHub。
原文摘要 · Abstract (English)
Mobile robot path planning in complex environments remains a significant challenge, especially in achieving efficient, safe and robust paths. The traditional path planning techniques like DRL models typically trained for a given configuration of the starting point and target positions, these models only perform well when these conditions are satisfied. In this paper, we proposed a novel path planning framework that embeds Large Language Models to empower mobile robots with the capability of dynamically interpreting natural language commands and autonomously generating efficient, collision-free navigation paths. The proposed framework uses LLMs to translate high-level user inputs into actionable waypoints while dynamically adjusting paths in response to obstacles. We experimentally evaluated our proposed LLM-based approach across three different environments of progressive complexity, showing the robustness of our approach with llama3.1 model that outperformed other LLM models in path planning time, waypoint generation success rate, and collision avoidance. This underlines the promising contribution of LLMs for enhancing the capability of mobile robots, especially when their operation involves complex decisions in large and complex environments. Our framework has provided safer, more reliable navigation systems and opened a new direction for the future research. The source code of this work is publicly available on GitHub.
