| Simulation is the imitation of a real-world process or system over time. Previously, we dealt with simple two-dimensional simulations. Very sophisticated three-dimensional systems can also be simulated. Simulation is a very important part of the ROS and robot development process as it allows the robot to be programmed and experimented without having a physical robot. Robot simulation is an important tool for every robot builder. A well-developed simulator lets you quickly test algorithms, customize robots, and even train artificial intelligence. There are different types of simulators for various purposes. The Gazebo is a universal simulator for a wide variety of aims, from mobile robots to autonomous vehicles (AVs). However, AVs simulators need powerful graphical engines to create a virtual environment as close to the real one. This is beyond the Gazebo power and you can find this feature in the new modern AV simulator such as SVL simulator or CARLA. | Simulation is the imitation of a real-world process or system over time.

| In the first step, we chose [[http://gazebosim.org/|Gazebo]] as the simulator and in the following focused on the SVL simulator as the main AV simulator. Gazebo offers the ability to accurately and efficiently simulate multiple robots in complex indoor and outdoor environments. The simulator has a full-featured physics engine, high-quality graphics, and good ROS compatibility. It is possible to simulate different motors and joints and different sensors, such as cameras and LiDARs. Gazebo simulator can be run from the command line (//headless//) or with a nice graphical user interface | In the first step, we chose [[http://gazebosim.org/|Gazebo]] as the simulator, and in the following focused on the SVL simulator as the main AV simulator.

| Gazebo is already installed with the full ROS installation. But in case that you don't install ROS in the full mode you can use this automatic installation script for installing Gazebo: | The gazebo is already installed with the full ROS installation.
