There is a fault, invoking "make run_tests_elevation_map_msg run_tests_elevation_mapping -j12 -l12" failed, when I catkin_make run_tests_elevation_map_msg run_tests_elevation_mapping.Why ?

Hi @hello1future,
can you provide a screenshot of your console?

What should I do? Can you help me?I'm a new ros guy.
Thank you very much.

This behavior is intended. The problem is that no depth and pose data gets generated in the example. The data needs to come from another source. Usually, it comes from

• a real robot platform,
• a bag that gets replayed, or
• a simulation environment, e.g. Gazebo.

Are you planning to use the software in simulation or with a real platform?

[hello1future]

Thank you for your answer.
We use it in a simulation environment, if it can meet our requirements, in the later, we can use it on a real platform.

[maximilianwulf]

Okay, then you have to run the simulation together with elevation mapping.
Make sure that elevation mapping subscribes to your point cloud topic and pose topic. For the simple_demos.launch you can define the parameters in the file simple_demo_robot.yaml.
I hope this helps.

Thank you very much.
I want to test elevation_mapping with Turtlebot3 simulation environment. Feasible?

[maximilianwulf]

I am not familiar with the Turtlebot3 simulation environment.
If it has a pose, i.e. from odometry, and a point cloud, then it should work.

Would be interesting if you can share your experience.

[hello1future]

What's the reason why this error? Can you help me?

[maximilianwulf]

Elevation mapping is not subscribed to the correct topic name. You have to change it in this file: https://github.com/ANYbotics/elevation_mapping/blob/master/elevation_mapping_demos/config/robots/simple_demo_robot.yaml
Update 'point_cloud_topic' and 'robot_pose_with_covariance_topic'.

While running the Turtlebot3 simulation, you can list the available ros topic names with the command
rostopic list

Search for the point cloud and pose topic.

Hi @hello1future, this pull request #105 integrates elevation mapping in the turtlebot3 simulation.
I hope this helps.
Feel free to reopen the thread if you have any problems.

In order to run elevation mapping you don't need to compile the unit tests.
