depends on https://github.com/ETHZ-RobotX/smb_dev/pull/143

This was a running elevation mapping config that one could start off for next year

[nubertj]

if everything is cloned and smb_msf_graph is built, then the elevation map should show up with the command

roslaunch smb_msf_graph smb_msf_graph_o3d_replay.launch

I will test it, thank you so much Julian! :D

I will help to test on Mac. Thanks, Julian.

Thanks, also I added and tested the tightly fused wheel odometry yesterday, which uses the raw wheel speeds directly and seems to work fairly well.
Will send you guys some instructions soon.

Sorry I was quite busy with my internship and had to travel, I should be able to test it either next or the week or the week after that, as my internship is finished then and I'll be back in Switzerland.

I just changed the open3d topic, which was still outdated when trying to run it again. This current version works for me.
