ROS + Ignition Gazebo demos

This package contains demos showing how to use Ignition Gazebo with ROS.

Air pressure

Publishes fluid pressure readings.

roslaunch ros_ign_gazebo_demos air_pressure.launch

Camera

Publishes RGB camera image and info.

Images can be exposed to ROS through ros_ign_bridge or ros_ign_image.

Using the image bridge (unidirectional, uses image_transport):

roslaunch ros_ign_gazebo_demos image_bridge.launch

Using the regular bridge:

roslaunch ros_ign_gazebo_demos camera.launch

Diff drive

Send commands to a differential drive vehicle and listen to its odometry.

roslaunch ros_ign_gazebo_demos diff_drive.launch

Then send a command

rostopic pub /model/vehicle_blue/cmd_vel geometry_msgs/Twist "{linear: {x: 5.0}, angular: {z: 0.5}}"

Depth camera

Depth camera data can be obtained as:

• sensor_msgs/Image, through ros_ign_bridge or ros_ign_image
• sensor_msgs/PointCloud2, through ros_ign_point_cloud (See issue #40)

Using the image bridge (unidirectional, uses image_transport):

roslaunch ros_ign_gazebo_demos image_bridge.launch

Using Ignition Gazebo plugin:

roslaunch ros_ign_gazebo_demos depth_camera.launch

GPU lidar

GPU lidar data can be obtained as:

• sensor_msgs/LaserScan, through the ros_ign_bridge
• sensor_msgs/PointCloud2, through the ros_ign_bridge or ros_ign_point_cloud (See issue #40)

Using the bridge:

roslaunch ros_ign_gazebo_demos gpu_lidar_bridge.launch

Using Ignition Gazebo plugin:

roslaunch ros_ign_gazebo_demos gpu_lidar.launch

IMU

Publishes IMU readings.

roslaunch ros_ign_gazebo_demos imu.launch

Magnetometer

Publishes magnetic field readings.

roslaunch ros_ign_gazebo_demos magnetometer.launch

RGBD camera

RGBD camera data can be obtained as:

• sensor_msgs/Image, through ros_ign_bridge or ros_ign_image
• sensor_msgs/PointCloud2, through ros_ign_bridge or ros_ign_point_cloud (See issue #40)

Using the image bridge (unidirectional, uses image_transport):

roslaunch ros_ign_gazebo_demos image_bridge.launch

Using the regular bridge:

roslaunch ros_ign_gazebo_demos rgbd_camera_bridge.launch

Using Ignition Gazebo plugin:

roslaunch ros_ign_gazebo_demos rgbd_camera.launch

Battery

Get the current state of a battery.

roslaunch ros_ign_gazebo_demos battery.launch

Then send a command so the vehicle moves and drains the battery

rostopic pub /model/vehicle_blue/cmd_vel geometry_msgs/Twist "{linear: {x: 5.0}, angular: {z: 0.5}}"

Create entity

Launch simulation and spawn entities:

• Sphere from URDF loaded into ROS param
• Box from SDF file on Ignition Fuel
• Cylinder from SDF file

roslaunch ros_ign_gazebo_demos create.launch
