Simulating the robotic arm with Xtion Pro

Now that we have learned about the camera plugin definition in Gazebo, we can launch the complete simulation using the following command:

$ roslaunch seven_dof_arm_gazebo seven_dof_arm_with_rgbd_world.launch  

We can see the robot model with a sensor on the top of the arm, as shown here:

We can now work with the simulated rgb-d sensor as if it were directly plugged into our computer. So we can check whether it provides the correct image output.
