🤖 AI Summary
This study addresses the challenge of simultaneously achieving efficiency, safety, and social compliance in autonomous social navigation, as well as the reliance of existing reinforcement learning methods on human-state priors. To this end, we propose JESSI, an end-to-end framework that directly maps raw LiDAR observations to control commands via multi-task reinforcement learning. JESSI parameterizes a continuous action space using Dirichlet distributions with deterministic boundaries to guarantee physical safety, and incorporates attention mechanisms to extract probabilistic human states for interpretable, socially aware decision-making. Both simulation and real-world robot experiments demonstrate that JESSI jointly optimizes multiple performance metrics without requiring manual priors, significantly outperforming baseline methods in navigation success rate and social compliance.
📝 Abstract
Autonomous social navigation requires balancing efficiency, physical safety, and social compliance. Reinforcement Learning (RL) methods provide a viable and effective solution but often rely on unrealistic assumptions, such as the knowledge of humans'position and velocity. In this paper, we introduce JESSI (JAX-based E2E Safe Social Interpretable navigation), a lightweight end-to-end RL framework that maps raw LiDAR scans directly to kinematically feasible control commands. JESSI enhances safety via Dirichlet-parameterized continuous action spaces and deterministic bounding, while an integrated attention-based perception module extracts probabilistic human states for interpretable, socially aware decision-making. Through extensive simulations and real-world deployment on a differential-drive robot, we demonstrate that jointly optimizing the RL policy with a supervised perception signal in a multi-task paradigm enhances social behavior. Ultimately, JESSI is able to balance high navigation success rates and superior social behaviors compared to state-of-the-art baselines.
