StepNav: Efficient Planning with Structured Trajectory Priors

Project Page | Paper | Code

Official PyTorch implementation of StepNav, an efficient visual navigation framework accepted at ICRA 2026.

💡 Abstract

We present StepNav, an efficient planning framework for visual navigation that generates reliable trajectories using structured trajectory priors. Unlike existing methods that rely on unstructured noise, StepNav leverages multi-modal trajectory initialization combined with conditional flow matching for efficient and safe path generation.

🪛 Installation

git clone https://github.com/LuoXubo/StepNav.git
cd StepNav
conda create -n stepnav python=3.8
conda activate stepnav
pip install -r requirements.txt
pip install -e .

🤖 Deployment

The deployment code will be released soon. Stay tuned!
