slam gmapping real time on rviz
Hi all,
I am doing slam gmapping on my robot. i run rviz so that I can visualise the map real time. However, the map seems to take a long time before appearing.
rostopic echo /scan provides data quickly. rostopic echo /map_metadata about 40seconds before data is being churned. rostopic echo /map gives a huge array of -1
since map_metadata has a delay 40 seconds, i am guessing this is the cause for the delay in the visualisation of map in rviz. Is there a parameter where i can tune to fasten map output?
Thank you.
