摘要:

在由非holonomic机器人组成的多智能体系统中,非协调拥挤环境中的自主导航极具挑战性。我们的主要目标是开发一种新颖的、快速的、基于传感器的自主导航控制器,该控制器可以直接计算控制命令,以在与其他智能体共存时实现安全的移动。我们提出了一种输入受限的反馈控制器,专门设计用于非holonomic移动机器人,并对相关不变集进行表征。不变集是维持在非协调智能体中稳定性和安全性的关键。然后我们提出了一种规划策略,战略性地引导不变集的生成向智能体的目标方向发展。这使智能体能够直接计算理论上安全的控制输入,而无需显式要求预先规划的路径/轨迹来可靠地在拥挤的多智能体环境中导航。通过硬件实验验证了我们技术的实用性,并通过并行计算来缩短合成安全控制命令的计算时间。所提出的方法在需要基于运行时感知安全边界的快速控制计算的拥挤多智能体场景中具有潜在应用。

英文摘要:

Self-navigation in non-coordinating crowded environments is formidably challenging within multi-agent systems consisting of non-holonomic robots operating through local sensing. Our primary objective is the development of a novel, rapid, sensor-driven, self-navigation controller that directly computes control commands to enable safe maneuvering while coexisting with other agents. We propose an input-constrained feedback controller meticulously crafted for non-holonomic mobile robots and the characterization of associated invariant sets. The invariant sets are the key to maintaining stability and safety amidst the non-cooperating agents. We then propose a planning strategy that strategically guides the generation of invariant sets toward the agent's intended target. This enables the agents to directly compute theoretically safe control inputs without explicitly requiring pre-planned paths/trajectories to reliably navigate through crowded multi-agent environments. The practicality of our technique is demonstrated through hardware experiments, and the ability to parallelize computations to shorten computational durations for synthesizing safe control commands. The proposed approach finds potential applications in crowded multi-agent scenarios that require rapid control computations based on perceived safety bounds during run-time.
