I am new to ROS and working on a project using 2 VLP-16 LIDAR sensors. How can I visualize the laser scan of two VLP-16 sensors on 1 laptop in rviz?

I am using ROS Kinetic on Ubuntu 16.04.5. Can you please provide detailed description for the solution.

What have you tried so far?

Connected 1 VLP16 through ethernet and the other through ethernet to USB adaptor. Then, we laucnhed rviz but we are only able to get the scan of only 1 LIDAR. Two ethernet connections appear on connections tab on ubuntu and we are only able to visualize the data from the one we chose to connect.

I mean with ROS and RViz. What have you tried so far? How are you running/launching everything? Configurations, launch files, etc.

We have followed every step in the "Getting Started with VLP-16" ros page. The link is http://wiki.ros.org/velodyne/Tutorial... We have been able to visualize the data from 1 lidar using this tutorial. However we would like to see data from both lidar

Can you please update your question with a copy and paste of the output of

unfrotunately I do not have the sensor with me. Do you have a method to connect to LIDARs to 1 laptop and visualize data on rviz?

No, I can't help with the physical setup. But, with ROS you should have each LIDAR publishing on its own topic and then visualize each topic with RViz.

If you need help with stuff that isn't ROS-related, then you should try asking on the Robotics Stack Exchange
