# 1 **rslidar_sdk**
[中文介绍](README_CN.md)
## 1 Introduction
**rslidar_sdk** is the Software Development Kit of the RoboSense Lidar based on Ubuntu. It contains:
+ The lidar driver core [rs_driver](https://github.com/RoboSense-LiDAR/rs_driver),
+ The ROS support,
+ The ROS2 support,
To get point cloud through ROS/ROS2, please just use this SDK.
To integrate the Lidar driver into your own projects, please use the rs_driver.
### 1.1 LiDAR Supported
- RS-LiDAR-16
- RS-LiDAR-32
- RS-Bpearl
- RS-Helios
- RS-Helios-16P
- RS-Ruby-128
- RS-Ruby-80
- RS-Ruby-48
- RS-Ruby-Plus-128
- RS-Ruby-Plus-80
- RS-Ruby-Plus-48
- RS-LiDAR-M1
- RS-LiDAR-M2
- RS-LiDAR-M3
- RS-LiDAR-E1
- RS-LiDAR-MX
### 1.2 Point Type Supported
- XYZI - x, y, z, intensity
- XYZIRT - x, y, z, intensity, ring, timestamp
## 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.
```sh
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](https://github.com/RoboSense-LiDAR/rslidar_sdk/releases) 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
sudo apt-get install -y libyaml-cpp-dev
```
### 3.4 libpcap (Essential)
version: >= v1.7.4
Installation:
```sh
sudo apt-get install -y libpcap-dev
```
## 4 Compile & Run
### 4.1 Compile with ROS catkin tools
(1) Create a new workspace folder, and create a *src* folder in it. Then put the rslidar_sdk project into the *src* folder.
(2) Go back to the root of workspace, run the following commands to compile and run. (if using zsh, replace the 2nd command with *source devel/setup.zsh*).
```sh
catkin_make
source devel/setup.bash
roslaunch rslidar_sdk start.launch
```
### 4.2 Compile with ROS2 colcon
(1) Create a new workspace folder, and create a *src* folder in it. Then put the rslidar_sdk project in the *src* folder.
(2) Download the packet definition project in ROS2 through [link](https://github.com/RoboSense-LiDAR/rslidar_msg), then put the project rslidar_msg in the *src* folder you just created.
(3) Go back to the root of workspace, run the following commands to compile and run. (if using zsh, replace the 2nd command with *source install/setup.zsh*).
```sh
colcon build
source install/setup.bash
ros2 launch rslidar_sdk start.py
```
Another version of start.py may be used, since it is different on different versios of ROS2. For example, elequent_start.py is used instead for ROS2 elequent.
