Hi all,
I am study using Slam_gmapping.
I ran roscore, stage_ros first. These are the list of topic:
ubuntu@tegra-ubuntu:~$ rostopic list
/base_pose_ground_truth
/base_scan
/clock
/cmd_vel
/odom
/rosout
/rosout_agg
/tf
Then I run gmapping and it stop at Registering First Scan
ubuntu@tegra-ubuntu:~$ rosrun gmapping slam_gmapping scan:=base_scan

Registering First Scan
I also tried with tutorial in this link but I still have same problem
[http://wiki.ros.org/slam_gmapping/Tutorials/MappingFromLoggedData#record](http://wiki.ros.org/slam_gmapping/Tutorials/MappingFromLoggedData#record)
Please let me know if I missed anything? Or any suggestion the method to track the problem are welcome.
I run ROS on Jetson TX1
