Problem

Autoware's calibration tool expects the Lidar to publish to "/points_raw", but our current driver publishes to "/velodyne_point_cloud"

Solution

Remap "/velodyne_point_cloud" to "/points_raw" in the decoder launch file

Relevant issue in Autoware can be found here

@mitchellsayer is this a viable solution? or is "/velodyne_point_cloud" a topic that some other node subscribes to?

If it is not, we can write a node to simply copy the data to another topic.

This tool can relay the message from one topic name to another that can be specified by you.

@menson168 is there a way to embed that in a launch file so I don't need to add an extra command step to the initialization process?

@menson168 have we found any way to automate this process? or else we may need an extra step upon startup.

otherwise, we'd probably need to modify @mitchellsayer's code

@Francisco-Ibarra07 might be easier just have a shell script as the official startup script to include the remapper and the startup launch file

I think we're good for now! This is relatively low priority at the moment
