[ros-users] Converting Logfile into Carmen Format

Fri Jan 7 09:54:24 UTC 2011

Hi everyone,

Are there any news concerning this topic? I'm very interested in a converter
that generates .bag files from CARMEN or Player format logfiles, so logs
from the radish repository can directly be fed into ROSified SLAM approaches
for testing and comparison.

regards,
Stefan
