Hello everybody,

I'm trying to bring up a navigation stack on a custom robot. The Warning I'm getting is the following :

[ WARN] [1349902108.687242123, 83.600000000]: Waiting on transform from /base_footprint to /map to become available before running costmap, tf error: Lookup would require extrapolation into the past.  Requested time 83.500000000 but the earliest data is at time 1349902098.858861163, when looking up transform from frame [/base_footprint] to frame [/map]

My launch file looks like this:

The static transform publisher doesn't solve the problem either ... .

I would be happy about any advice.

Best regards,

Thomas

Hello Thomas,

The problem is that stage is working with simulation time (starting at 0) but gmapping is working on real time. Adding

<param name="/use_sim_time" value="true"/>

after the should solve the problem.
