Gazebo

An open-source robot simulator integrated with ROS, providing physics simulation (ODE, Bullet, DART, Simbody), 3D rendering, and sensor models. Gazebo is the traditional simulation environment for ROS-based robot development. Gazebo Classic is being superseded by Gazebo (formerly Ignition), which offers improved modularity, rendering, and distributed simulation.
