Hello,

First, I'd like to say that i read other topic that had this error but couldn't find any solution out of the 15 post i read.

I'm trying to do a navigation simulation using gazebo and rviz on ros kinetic and ubuntu 16.04.7.

In my navigation launch file I use 4 nodes which are move_base, amcl, map_server and rviz. Link of the files at the end of the post

The problem is that few seconds after launch I start get warning about the robot position which is apparently not received or outdated. The robot is displayed on rviz but cannot navigate at all.

This bellow is the warnings i get when i start navigation.launch I'm not sure to really understand the warnings.

process[map_server-2]: started with pid [11794]

Also if I wait for a while i get this error :

Extrapolation Error looking up robot pose: Lookup would require extrapolation at time 5725.281000000, but only time 5726.151000000 is in the buffer, when looking up transform from frame [base_footprint] to frame [map]
