Welcome to the world of Habitat-Sim, a high-performance physics-enabled 3D simulator designed for exploring indoor and outdoor spaces with ease. This article provides a user-friendly guide on how to install, test, and troubleshoot Habitat-Sim, helping you unlock the potential of this cutting-edge platform.

Installation

Habitat-Sim can be installed in several ways to suit your needs. Here’s a breakdown of the methods:

• Via Conda: Recommended for most users, offers stable release and nightly builds.
• Via PIP: Use pip to compile the latest headless build with Bullet. (See specific build instructions for common issues.)
• Via Docker: Access the latest version for the Habitat Challenge (updated annually).
• Via Source: Ideal for development purposes, refer to build instructions for potential issues.

Recommended Method: Using Conda Packages

To install using conda, follow these steps:

1. **Create a Conda environment**:

conda create -n habitat python=3.9 cmake=3.14.0

2. **Activate the environment**:

conda activate habitat

3. **Install Habitat-Sim**:

Select your installation option based on your system:

• For machines with a display:

conda install habitat-sim -c conda-forge -c aihabitat

• For headless machines:

conda install habitat-sim headless -c conda-forge -c aihabitat

• For physics-enabled installs:

conda install habitat-sim withbullet -c conda-forge -c aihabitat

Testing Your Installation

Once you have installed Habitat-Sim, it’s time to test it! Start by downloading some 3D assets:

python -m habitat_sim.utils.datasets_download --uids habitat_test_scenes --data-path pathtodata

Use these assets to test the interactive viewer:

For C++:

habitat-viewer pathtodatascene_datasetshabitat-test-scenesskokloster-castle.glb

For Python:

python examplesviewer.py --scene pathtodatascene_datasetshabitat-test-scenesskokloster-castle.glb

In the interactive viewer:

• Use WASD to move around.
• Use the mouse or arrow keys to change your gaze direction.

Understanding the Functionality: An Analogy

Think of Habitat-Sim like a virtual park full of playgrounds and different zones (the spaces and datasets) where your robot friends (the agents) come to play. You can configure various equipment (the sensors) like cameras and motion trackers, allowing your robot to navigate and interact with this park. Just like how you would take a new scooter for a spin to see how it turns and stops, you’ll be testing your robots to see how they move and interact within the environments you’ve created.

Troubleshooting Ideas

If you encounter issues during installation or testing, consider the following:

• Make sure your DISPLAY environment variable is unset if you face display issues on a remote machine. You can do this by running unset DISPLAY.
• If you’re experiencing libGL errors, check the location of your libGL to confirm it’s correctly set up. Refer to this guide for assistance.
