In order to make simulations with our robots in ROS, we are going to use Gazebo.
Gazebo (http://Gazebosim.org/) is a multi-robot simulator for complex indoor and outdoor environments. It is capable of simulating a population of robots, sensors, and objects in a three-dimensional world. It generates both realistic sensor feedback and physically plausible interactions between objects.
Gazebo is now independent from ROS and is installed as a standalone package in Ubuntu. In this section, we will learn how to interface Gazebo and ROS. You will learn how to use the model created before, how to include a laser sensor and a camera, and how to move it as a real robot.
We are going to use the model that we ...
