让机器人根据障碍物语义动态调整安全距离,提升复杂环境下的导航安全性。

Safe-SAGE: Social-Semantic Adaptive Guidance for Safe Engagement through Laplace-Modulated Poisson Safety Functions

  • 用泊松安全函数融合语义信息,实现不同障碍物差异化安全控制。
  • 通过多层安全滤波器,在动态环境中保持上下文感知的实时安全路径。
  • 适用于需要理解行人、车辆等语义场景的腿式机器人自主导航。

传统安全关键控制方法(如控制屏障函数)存在语义盲区,对所有障碍物一视同仁。本文提出Safe-SAGE框架,通过拉普拉斯引导场调制泊松安全函数(PSF),将高层语义理解与底层安全控制相融合。系统通过融合多传感器点云与基于视觉的实例分割及持续目标追踪,实现超越摄像头视域的实时语义感知。随后采用多层安全滤波器调节系统输入,包含模型预测控制层与控制屏障函数层,均利用PSF和引导场通量调制,针对不同障碍物引入差异化的保守性与多智能体通行规范。该框架使腿式机器人能够在语义丰富的动态环境中,依据上下文动态调整安全裕度,实现安全导航。

原文摘要 · Abstract (English)

Traditional safety-critical control methods, such as control barrier functions, suffer from semantic blindness, exhibiting the same behavior around obstacles regardless of contextual significance. This limitation leads to the uniform treatment of all obstacles, despite their differing semantic meanings. We present Safe-SAGE (Social-Semantic Adaptive Guidance for Safe Engagement), a unified framework that bridges the gap between high-level semantic understanding and low-level safety-critical control through a Poisson safety function (PSF) modulated using a Laplace guidance field. Our approach perceives the environment by fusing multi-sensor point clouds with vision-based instance segmentation and persistent object tracking to maintain up-to-date semantics beyond the camera's field of view. A multi-layer safety filter is then used to modulate system inputs to achieve safe navigation using this semantic understanding of the environment. This safety filter consists of both a model predictive control layer and a control barrier function layer. Both layers utilize the PSF and flux modulation of the guidance field to introduce varying levels of conservatism and multi-agent passing norms for different obstacles in the environment. Our framework enables legged robots to safely navigate semantically rich, dynamic environments with context-dependent safety margins.
