iGibson: A Simulation Environment to train Robots in Large Realistic Interactive Scenes

iGibson is a simulation environment providing fast visual rendering and physics simulation based on Bullet. iGibson is equipped with fifteen fully interactive high quality scenes, hundreds of large 3D scenes reconstructed from real homes and offices, and compatibility with datasets like CubiCasa5K and 3D-Front, providing 8000+ additional interactive scenes. Some of the features of iGibson include domain randomization, integration with motion planners and easy-to-use tools to collect human demonstrations. With these scenes and features, iGibson allows researchers to train and evaluate robotic agents that use visual signals to solve navigation and manipulation tasks such as opening doors, picking up and placing objects, or searching in cabinets.

Latest Updates

[8/9/2021] Major update to iGibson to reach iGibson 2.0, for details please refer to our arxiv preprint.

• iGibson 2.0 supports object states, including temperature, wetness level, cleanliness level, and toggled and sliced states, necessary to cover a wider range of tasks.
• iGibson 2.0 implements a set of predicate logic functions that map the simulator states to logic states like Cooked or Soaked.
• iGibson 2.0 includes a virtual reality (VR) interface to immerse humans in its scenes to collect demonstrations.

[12/1/2020] Major update to iGibson to reach iGibson 1.0, for details please refer to our arxiv preprint.

• Release of iGibson dataset that includes 15 fully interactive scenes and 500+ object models annotated with materials and physical attributes on top of existing 3D articulated models.
• Compatibility to import CubiCasa5K and 3D-Front scene descriptions leading to more than 8000 extra interactive scenes!
• New features in iGibson: Physically based rendering, 1-beam and 16-beam LiDAR, domain randomization, motion planning integration, tools to collect human demos and more!
• Code refactoring, better class structure and cleanup.

[05/14/2020] Added dynamic light support 🔦

[04/28/2020] Added support for Mac OSX 💻

Documentation

The documentation for iGibson can be found here: iGibson Documentation. It includes installation guide (including data download instructions), quickstart guide, code examples, and APIs.

If you want to know more about iGibson, you can also check out our webpage, iGibson 2.0 arxiv preprint and iGibson 1.0 arxiv preprint.

Dowloading the Dataset of 3D Scenes

For instructions to install iGibson and download dataset, you can visit installation guide and dataset download guide.

There are other datasets we link to iGibson. We include support to use CubiCasa5K and 3DFront scenes, adding up more than 10000 extra interactive scenes to use in iGibson! Check our documentation on how to use those.

We also maintain compatibility with datasets of 3D reconstructed large real-world scenes (homes and offices) that you can download and use with iGibson. For Gibson Dataset and Stanford 2D-3D-Semantics Dataset, please fill out this form. For Matterport3D Dataset, please fill in this form and send it to [email protected]. Please put "use with iGibson simulator" in your email. Check our dataset download guide for more details.

Using iGibson with VR

If you want to use iGibson VR interface, please visit the [VR guide (TBA)].

Contributing

This is the github repository for iGibson (pip package igibson) 2.0 release. (For iGibson 1.0, please use 1.0 branch.) Bug reports, suggestions for improvement, as well as community developments are encouraged and appreciated. Please, consider creating an issue or sending us an email.

The support for our previous version of the environment, Gibson, can be found in the following repository.

Acknowledgments

iGibson uses code from a few open source repositories. Without the efforts of these folks (and their willingness to release their implementations under permissable copyleft licenses), iGibson would not be possible. We thanks these authors for their efforts!
