Gazebo Fundamentals
Gazebo is a 3D simulation environment for robotics that provides realistic physics, high-quality graphics, and convenient programmatic interfaces.
Key Components
System Requirements
Gazebo is computationally intensive. Ensure your system meets the minimum requirements:
- GPU: NVIDIA or AMD with OpenGL 3.3+ support
- RAM: Minimum 8GB (16GB recommended for complex simulations)
- OS: Ubuntu 22.04 LTS (recommended) or Ubuntu 20.04 LTS
- Physics Engine (ODE, Bullet, Simbody)
- Rendering Engine (OGRE)
- Sensors (cameras, lidar, IMU, etc.)
- Robot models and world files
Performance Tip
Start with simple worlds and gradually add complexity. Disable unnecessary sensors and reduce physics update rates if experiencing lag. Use the real_time_factor metric to monitor simulation performance.
