Gazebo
A powerful robotics simulation platform for realistic environments, sensors, and autonomous systems testing
Gazebo is an advanced 3D robotics simulator designed to help engineers and researchers test robots, sensors, and autonomous behaviors in realistic virtual environments. It enables safe and cost-effective development by allowing teams to validate navigation, perception, and control logic before deploying to real hardware. With physics-based simulation and rich environment modeling, Gazebo supports rapid iteration for complex robotics projects.
Widely used in research labs, industrial robotics, and autonomous vehicle development, Gazebo integrates seamlessly with common robotics stacks such as ROS. It supports high-fidelity sensor simulation (e.g., LiDAR, camera, IMU, GPS), dynamic interactions, and configurable worlds. This helps teams reduce risk, improve system performance, and accelerate validation across diverse mission scenarios.
