ROS Programming: Building Powerful Robots

Adding the laser scanner to Gazebo

We add the laser scanner on the top of Gazebo in order to perform high-end operations such as autonomous navigation using this robot. Here, we can see that an extra code section needed to be added in diff_wheeled_robot.xacro to have the laser scanner on the robot:
