🏠 Introduction

InternNav is an All-in-one open-source toolbox for embodied navigation based on PyTorch, Habitat and Isaac Sim.

Highlights

• Modular Support of the Entire Navigation System

We support modular customization and study of the entire navigation system, including vision-language navigation with discrete action space (VLN-CE), visual navigation (VN) given point/image/trajectory goals, and the whole VLN system with continuous trajectory outputs.

• Compatibility with Mainstream Simulation Platforms

The toolbox is compatible with different training and evaluation requirements, supporting different environments for the usage of mainstream simulation platforms such as Habitat and Isaac Sim.

• Comprehensive Datasets, Models and Benchmarks

The toolbox supports the most comprehensive 6 datasets & benchmarks and 10+ popular baselines, including both mainstream and our established brand new ones.

• State of the Art

The toolbox supports the most advanced high-quality navigation dataset, InternData-N1, which includes 3k+ scenes and 830k VLN data covering diverse embodiments and scenes, and the first dual-system navigation foundation model with leading performance on all the benchmarks and zero-shot generalization capability in the real world, InternVLA-N1.

👥 Contribute

If you would like to contribute to InternNav, please check out our contribution guide. For example, raising issues, fixing bugs in the framework, and adapting or adding new policies and data to the framework.

Note: We welcome the feedback of the model's zero-shot performance when deploying in your own environment. Please show us your results and offer us your future demands regarding the model's capability. We will select the most valuable ones and collaborate with users together to solve them in the next few months :)
