Cannot run the mapping tutorial [closed]
Hi,
Maybe my question is a bit dump because I am very new to hector slam and even to ROS. I have installed ROS and hector slam (indigo). When I was trying to do the tutorial, after I typed "roslaunch hector_slam_launch tutorial.launch" and press enter, Rviz started fine with no error. I can rotate the grid and saw Global Status is in red text (no data feeding into Rviz).
Then I typed "rosbag play Team_Hector_MappingBox_RoboCup_2011_Rescue_Arena.bag --clock" in another console and there is no error shown. I could see the [RUNNING] line being showed and I guess the data is being fed to Rviz?
However, there is nothing shown in Rviz, I can still rotate the grid but there is no map being created. Also, I saw the Global Status became green and there was a check sign. I could also see the "ROS Elapsed" at the bottom is running.
When I added a TF, I could see two coordinates moving but there is just no map.
Can anyone help me on this please? Thanks
