Ion dynamics and selectivity of Nav channels from molecular dynamics simulation
, 2021The voltage-gated sodium (Nav) channels are crucial in initiating and propagating action potentials in excitable cells. In this work, with atomistic molecular simulations employing conventional and advanced sampling techniques, we investigate the ...

Nav-R1: Reasoning and Navigation in Embodied Scenes
arXiv.orgEmbodied navigation requires agents to integrate perception, reasoning, and action for robust interaction in complex 3D environments. Existing approaches often suffer from incoherent and unstable reasoning traces that hinder generalization across diverse

SG-Nav: Online 3D Scene Graph Prompting for LLM-based Zero-shot Object Navigation
Neural Information Processing SystemsIn this paper, we propose a new framework for zero-shot object navigation. Existing zero-shot object navigation methods prompt LLM with the text of spatially closed objects, which lacks enough scene context for in-depth reasoning.

IEEE International Conference on Robotics and Automation
Vision-and-Language Navigation (VLN) tasks require an agent to follow textual instructions to navigate through 3D environments. Traditional approaches use supervised learning methods, relying heavily on domain-specific datasets to train VLN models ...

C-Nav: Distributed coordination in crowded multi-agent navigation
Robotics Auton. Syst., 2020In crowded multi-agent navigation, the motion of the agents is significantly constrained by the motion of the nearby agents. This makes planning paths very difficult and leads to inefficient global motion.

OLiVia-Nav: An Online Lifelong Vision Language Approach for Mobile Robot Social Navigation
IEEE International Conference on Robotics and AutomationService robots in human-centered environments such as hospitals, office buildings, and long-term care homes need to navigate while adhering to social norms to ensure the safety and comfortability of the people they are sharing the space with. Furthermore,
