将基于可达性的安全性融入多智能体交互的规划和控制

Infusing Reachability-Based Safety into Planning and Control for Multi-agent Interactions

Stanford University(斯坦福大学)

Xinrui Wang, Karen Leung, Marco Pavone

摘要:

在机器人自主堆栈中,规划器和控制器通常是分开设计的,并且用于不同的目的。因此,在确保机器人安全方面,往往存在责任分散的问题。我们建议,计划者和控制者应该共享相同的安全解释,但以不同但互补的方式应用这些知识。为了实现这一目标,我们使用汉密尔顿-雅可比(HJ)可达性理论在规划层面提供的前瞻性,以避免进入可能不可避免的碰撞区域的机器人规划。但是,仅凭这一点并不能保证安全。结合这HJ可达性注入计划,我们提出了一个最小干预的多智能体安全保护控制器也来自HJ可达性理论。安全控制器保持机器人的安全性,而不会过度影响规划器的性能。我们在多智能体高速公路场景中展示了我们提出的方法的好处,其中机器人汽车将获得奖励,以尽可能快地在交通中导航,并且我们表明,与其他安全控制器相比,我们的方法提供了强有力的安全保证,同时实现了最高的性能。

英文摘要:

Within a robot autonomy stack, the planner and controller are typically designed separately, and serve different purposes. As such, there is often a diffusion of responsibilities when it comes to ensuring safety for the robot. We propose that a planner and controller should share the same interpretation of safety but apply this knowledge in a different yet complementary way. To achieve this, we use Hamilton-Jacobi (HJ) reachability theory at the planning level to provide the robot planner with the foresight to avoid entering regions with possible inevitable collision. However, this alone does not guarantee safety. In conjunction with this HJ reachability-infused planner, we propose a minimally-interventional multi-agent safety-preserving controller also derived via HJ-reachability theory. The safety controller maintains safety for the robot without unduly impacting planner performance. We demonstrate the benefits of our proposed approach in a multi-agent highway scenario where a robot car is rewarded to navigate through traffic as fast as possible, and we show that our approach provides strong safety assurances yet achieves the highest performance compared to other safety controllers.
