Need Help with laser_filter package
I have been trying to get the laser filter package to work and have been asking questions as seen here. I understand that the turtlebot3 uses the /scan
topic and not the \base_scan
topic. so I removed this line
<remap from="scan" to="base_scan"/>, from my launch file. I get an error when I do this. I am unable to get it to work and am in need of a guide to do so. I have looked at the wiki for the package several times and sill cant figure it out.
Hi @distro
Take a look at this repo: https://github.com/ROBOTIS-GIT/turtle...
The launch file shows how laser filter is implemented
And .yaml file is here: https://github.com/ROBOTIS-GIT/turtle...
@osilva I installed the package in the link you proposed. I am getting this error now though when I launch the file.
I dont know how to fix this. I have no idea what two launch files or source code files are have nodes with same name
I think if you try to run this example along your node for localization or mapping it would be a problem. I sent you this more so you can see how it was implemented the
laser filter
node is implemented so you can modify your launch file oryaml
if need to@osilva it seemed to be working then it started giving me these errors. let me show you my launch file now.
I think the sequence may matter. So perhaps try:
