Hi everybody.

I just controlled two motors using ROS, however it is not a real time process.

I am just wondering what is the best easy way to make a pthread that runs in real time, which control the motors and can easily send messages to other ROS nodes.

Any help will be appreciate it

2018-11-01 10:09:36 -0500 marked best answer ros gmapping change scan topic

Dear all.

I have a new topic name for a LaserScan.

When I run:

rosrun gmapping slam_gmapping scan:=new_topic_name

The gmapping takes the data under the new topic name.

However when I run a launch file

node name="slam_gmapping" pkg="gmapping" type="slam_gmapping" args="new_topic_name"

respawn="false" output="screen">

The gmapping doesnt take the data under the new topic name, it takes instead the data from the scan topic.

Can somebody explain why and how to solve that issue.

In advance thank you to all.

Hi everybody

I have a [XYZ] point-cloud coordinates from a laser in ROS, I can actually visualize the map over rviz. However, I would like to visualized it over octomap in vriz, is that possible? do you have a small function I can get inspired?

I was told that I can do it with octomap_server, however I have no clue how to do it, dont you have a general steps how it can be implemented or even better some code I can get :)

Any help will be really appreciate it
