2 Download

2.1 Download via Git

Download the rslidar_sdk as below. Since it contains the submodule rs_driver, please also use git submodule to download the submodule properly.

git clone https://github.com/RoboSense-LiDAR/rslidar_sdk.git
cd rslidar_sdk
git submodule init
git submodule update

2.2 Download directly

Instead of using Git, user can also access rslidar_sdk_release to download the latest version of rslidar_sdk.

Please download the rslidar_sdk.tar.gz archive instead of Source code. The Source code zip file does not contain the submodule rs_driver, so it has to be downloaded manaully.

3 Dependencies

3.1 ROS

To run rslidar_sdk in the ROS environment, please install below libraries.

• Ubuntu 16.04 - ROS Kinetic desktop
• Ubuntu 18.04 - ROS Melodic desktop
• Ubuntu 20.04 - ROS Noetic desktop

For installation, please refer to http://wiki.ros.org.

It’s highly recommanded to install ros-distro-desktop-full. If you do so, the corresponding libraries, such as PCL, will be installed at the same time.

This brings a lot of convenience, since you don’t have to handle version conflict.

3.2 ROS2

To use rslidar_sdk in the ROS2 environment, please install below libraries.

• Ubuntu 16.04 - Not supported
• Ubuntu 18.04 - ROS2 Eloquent desktop
• Ubuntu 20.04 - ROS2 Galactic desktop
• Ubuntu 22.04 - ROS2 Humble desktop

For installation, please refer to https://index.ros.org/doc/ros2/Installation/Eloquent/Linux-Install-Debians/

Please do not install ROS and ROS2 on the same computer, to avoid possible conflict and manually install some libraries, such as Yaml.

3.3 Yaml (Essential)

version: >= v0.5.2

If ros-distro-desktop-full is installed, this step can be skipped

Installation:

```sh sudo apt-get update
