ROS+ign_gazebo
演示如何将ign_gazebo
与ROS一起使用的演示。
启动ign_gazebo
启动文件,例如:
ros2 launch ros_ign_gazebo ign_gazebo.launch.py ign_args:="shapes.sdf"
ros1使用roslaunch
空气压力
sensor_msgs/msg/FluidPressure
。 发布流体压力读数。
ros2 launch ros_ign_gazebo_demos air_pressure.launch.py
相机
发布RGB相机图像和信息。 图像可以通过ros_ign_bridge
或ROS ros_ign_image发布
。 使用图像桥接(单向,使用image_transport):
ros2 launch ros_ign_gazebo_demos image_bridge.launch.py
使用常规桥接:
ros2 launch ros_ign_gazebo_demos camera.launch.py
差速机器人
向差速驱动车辆发送命令并听其里程表。
ros2 launch ros_ign_gazebo_demos diff_drive.launch.py
然后取消暂停并发送命令
ros2 topic pub /model/vehicle_blue/cmd_vel geometry_msgs/msg/Twist "{linear: {x: 5.0}, angular: {z: 0.5}}"
深度相机
深度相机数据可通过以下方式获得:
sensor_msgs/msg/Image
,通过ros_ign_bridge
或ros_ign_image
sensor_msgs/msg/PointCloud2
,通过ros_ign_point_cloud
使用图像桥接(单向,使用image_transport):
ros2 launch ros_ign_gazebo_demos image_bridge.launch.py
使用ign_gazebo
件:
ros2 launch ros_ign_gazebo_demos depth_camera.launch.py
GPU激光雷达
GPU激光雷达数据可通过以下方式获得:
sensor_msgs/msg/LaserScan
,通过ros_ign_bridge
sensor_msgs/msg/PointCloud2
,通过ros_ign_bridge
或ros_ign_point_cloud
使用桥接:
ros2 launch ros_ign_gazebo_demos gpu_lidar_bridge.launch.py
使用ign_gazebo
插件:
ros2 launch ros_ign_gazebo_demos gpu_lidar.launch.py
内部惯性导航单元
发布IMU读数。
ros2 launch ros_ign_gazebo_demos imu.launch.py
磁力计
发布磁场读数。
ros2 launch ros_ign_gazebo_demos magnetometer.launch.py
RGBD相机
RGBD摄像机数据可通过以下方式获得:
sensor_msgs/msg/Image
,通过ros_ign_bridge
或ros_ign_image
sensor_msgs/msg/PointCloud2
,通过ros_ign_bridge
或ros_ign_point_cloud
使用图像桥接(单向,使用image_transport):
ros2 launch ros_ign_gazebo_demos image_bridge.launch.py
使用常规桥接:
ros2 launch ros_ign_gazebo_demos rgbd_camera_bridge.launch.py
使用ign_gazebo
插件:
ros2 launch ros_ign_gazebo_demos rgbd_camera.launch.py
电池
获取电池的当前状态。
ros2 launch ros_ign_gazebo_demos battery.launch.py
然后发送命令,使车辆行驶并消耗电池电量
