Appendix C RS-Ruby

ROS

Package

This appendix describes how to use  ROS to acquiring and visualizing the
measuring data from RS-Ruby.

C.1 Software Installation

1. Download and Install Ubuntu 16.04 OS.
2. Please refer the link (

http://wiki.ros.org/kinetic/Installation

) to install the ROS Kinetic .

3. Download and install libpcap-dev.

C.2 Compile RS-Ruby ROS Package

1. Create a workspace for ROS:

cd ~
mkdir -p catkin_ws/src

2. Copy the corresponding ros_rslidar_package into the ROS workspace under the path:
~/catkin_ws/src.

The

latest

ros_rslidar

driver

can

be

downloaded

from

https://github.com/RoboSense-LiDAR/ros_rslidar or contact Robosense support.
3. Build

：

cd ~/catkin_ws
catkin_make

4. Place the configuration file of corresponding LiDAR into PC from USB stick:
The configuration_data is in the USB stick shipped with the LiDAR. Copy the launch file
into specified folder. This path can be customized.
For example: rslidar_pointcloud/data/rs_ruby

C.3 Configure PC IP address

For the default RS-Ruby firmware, static IP address of PC is configured to
“192.168.1.102”, submask: “255.255.255.0”, gateway doesn’t need to configure.
After configuring the static IP, it can be examined in CMD with code ifconfig.

C.4 Display of the real-time data

1. Connect the RS-Ruby to PC via twister pair wire with RJ45 connector, power on it, then
wait for PC cognizing LiDAR.
2. An example launch file has been provided under path: rslidar_pointcloud/launch, in
order to starting the node that can be run to visualize the real-time point cloud data. Open
a terminal with a location as shown as below:

cd ~/catkin_ws
source devel/setup.bash
roslaunch rslidar_pointcloud rs_ruby.launch

3. Open a new terminal:

rviz
