[ROS Q&A] 085 - Basic usage of octomap_mapping package - Tutorial

In the ROS Q&A Tutorial, we will show you how to execute some basic functionalities of the octomap_mapping package: Creating an Octomap, saving the Octomap and providing the Octomap.

Thank you. It's very helpful for start using octomap.

[@muhammedyilmaz2907]

good tutorial ever i saw in youtube. Thanks

[@DanielMunoz-hr1vr]

Very useful, thank you, you save my semester! xD

[@TheConstruct]

Thanks for your comment. It really made our day! We are very happy to hear that our work is useful for you guys. Please share with your peers, that will help us a lot

Thanks you so much!!!!. I changed the odom frame and the slam with octomap works :D

[@mustafamohammed4205]

Thanks for the tutorial after 4 years still the best. I have a question which mapping algo is better in your opinion to work in warehouses rtab or octomap?

[@SaadKhan-pn9rt]

is there a way to increase the update time of the real time mapping? it was really slow when i did it and then i tweaked the resolution values in the octomap_mapping.launch file along with the upper and lower values of the clamping update policy but it doesnt seem to work. Plz help!

[@95663boy]

Hi, May i know why did the odom not exist despite i followed ur steps in rivz? I planned to use robosense lidar-16 to create a 3D mapping. thank you for helping

[@130music]

Thank you so much for your video. Following your tutorial, I have created an octomap with point cloud2. However, the PR2 robot arm doesn't consider the octomap as collision object when it was doing motion planning. Do you know the why?

[@zhefanx2783]

Very nice video. But when I follow your step in my turtlebot, it seems the octomap_mapping does not have any ros message in its published topic. And the rviz cannot visualize the pointcloud. I am using laser_geometry to convert the laser scan data into point cloud, is that the reason for this error?

[@drilyasmeo]

Hi Xu Zhefan, im also trying octomapiing for tb3. Could you do for your turtle simulation? plz contact at'; [e-mail]

[@zhefanx2783]

Dr Ilyas Meo Yes I solved the problem. It can work.

[@drilyasmeo]

@@zhefanx2783 Can you please share your Github? : [e-mail]

[@hanssarpei8687]

I did the exact same steps as you did, but my robot is not rotating at all on rviz. Its only looking in one way while the robot is rotating

[@purposestalk2110]

it says
ERROR: cannot launch node of type [octomap_server/octomap_server_node]: Cannot locate node of type [octomap_server_node] in package [octomap_server]. Make sure file exists in package path and permission is set to executable (chmod +x)

[@vincentdelphin3085]

Did you find a solution to this?

[@reynardlee2235]

@@vincentdelphin3085 have you ran "catkin_make"?

[@kaabachiamina4928]

thank you ! are you using a Velodyne VLP-16??

[@bakhtawarrehman5439]

Hi; can you please explai; how to do navigation using this algorithm?

[@TheConstruct]

We do explain how to use it for drone navigation in this course: goo.gl/eK3EvR

[@sameertodkar2504]

Is there a way to speed up the octomap server?

[@shrijank522]

Hi,
Is it possible to run this with a point cloud .ply file as generated from Google Cartographer?

[@vanhoabui5369]

why in step "rostopic list" , i can't see camera/depth/points topic

[@krisshcool6381]

hi, did you fix it? even i am facing the same issue
