Mastering ROS for Robotics Programming - Second Edition

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:

Figure 2: Simulation of seven-DOF arm with Asus Xtion Pro in Gazebo

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.
