根据
http://wiki.ros.org/Sensors/OrbbecAstra
主要有两个 ROS pack
http://wiki.ros.org/astra_camera
http://wiki.ros.org/astra_launch

apt 没有 melodic 的版本，所以尝试从源码安装一下。
根据
https://github.com/orbbec/ros_astra_camera 的 readme.md

1. sudo apt install ros-$ROS_DISTRO-rgbd-launch ros-$ROS_DISTRO-libuvc ros-$ROS_DISTRO-libuvc-camera ros-$ROS_DISTRO-libuvc-ros
2. ss; git clone https://github.com/orbbec/ros_astra_camera
3. 编译 astra sm --pkg=astra_camera
4. roscd astra_camera; ./scripts/create_udev_rules

使用：
roslaunch astra_camera astra.launch
或者 roslaunch astra_camera stereo_s.launch
