Revision history [back]

As the terminal log was not displayed here, I guess and give my suggestions:

1) check the slam_gmapping node whether died.

2) check the /odom topic which is also required by slam_gmapping, just like /scan. It seems that there is no tf between /odom and /base_link.

Maybe show more details of the output will be better for helping others understanding this question :)
